1 INTRODUCTION

The CIO-RELAY16 is a 16 channel relay interface board for ISA bus computers. The

board provides 16 Form C (SPDT) relays. The CIO-RELAY08 board is designed for

applications that require fewer relays and is identical to the RELAY16 board except

that only 8 relays are installed. The CIO-RELAY32 is two CIO-RELAY16s on a sin-

gle board while the CIO-RELAY24 is are CIO-RELAY32 with eight of the relays not

installed.

The /M versions (e.g. CIO-RELAY16/M and CIO-RELAY08/M) are identical to the

standard versions, but use Mercury wetted relays and offer quicker switch times, less

contact bounce and lower on-resistance than the standard models.

The CIO-RELAY16 family has been designed for control applications where a few

points of high voltage (or current) need to be controlled.

WARNING!

High voltages will be present on the CIO-RELAY16 family boards

when high voltage is connected to the CIO-RELAY16 connector.

Use extreme caution! Never handle the CIO-RELAY16 when sig-

nals are connected to the board through the connector.

DO NOT REMOVE THE PROTECTIVE PLATES FROM THE

CIO-RELAY16!

1.1 ACCESSORIES

The CIO-RELAY16 family are digital I/O boards with relay based signal conditioning

installed. Most accessory boards are intended to provide signal conditioning or easy

to access signal termination. In general, the CIO-RELAY16 will not require addi-

tional signal conditioning.

We recommend that under no circumstance should a screw terminal board be used to

connect high voltages to the CIO-RELAY16 series board. The CIO-RELAY16 is

intended to control high voltages. If you use a screw terminal board you will expose

yourself and others to those high voltage signals.

We recommend that you construct a safe cable to carry your signals directly from your

equipment to the CIO-RELAY16 connector.

2 QUICK START

The installation and operation of all four CIO-RELAY series boards is very similar.

Throughout this manual we use CIO-RELAY as a generic designation for the CIO-

RELAY08, CIO-RELAY16, CIO-RELAY24 and CIO-RELAY32. When required due

to the differences in the boards, the specific board name is used.

The CIO-RELAY boards are easy to use. This quick start procedure will help you

quickly and easily setup, install and test your board. We assume you already know

how to open the PC and install expansion boards. If you are unfamiliar or uncomfort-

able with board installation, please refer to your computer’s documentation.

We recommend you perform the software installation described in

the following sections prior to installing the board in your com-

puter. The InstaCalTM operations below will show you how to prop-

erly set the switches and jumpers on the board prior to physically

installing the board in your computer.

2.1 Install the InstaCalTM software

Windows 95, 98 and NT users install InstaCAL by running the SETUP.EXE program

included on your InstaCAL floppies or CD.

Windows 3.x and DOS users install the program by running the INSTALL.EXE pro-

gram supplied on your InstaCAL disk.

These installation routines will create all required folders/directories and unpack the

various pieces of compressed software. Simply run install and follow the on-screen

instructions. Remember where the installed files are placed, as you will need to access

them in the next step (the default location is on your main hard drive in a directory or

folder named C:\CB\).

2.2 Run InstaCalTM

To run InstaCalTM in the various forms of Windows, find the file named InstaCal.exe

using your file management system and double click your mouse on it. In DOS simply

type instacal and press the Enter key.

Once running, InstaCalTM provides four sub-menus (plus exit).

1. Select Install (either highlight it and hit enter of double click your

mouse on it).

2. Select Board #0 (select another number if Board #0 is already installed)

3. Select Board Type

4. Move through the selections and highlight the particular board you

are installing (e.g. CIO-RELAY08 or CIO-RELAY16/M).

Either double click on the board or hit enter.

5. The board’s default settings are then displayed. The board’s defaults are:

BASE ADDRESS: 300H (768 Decimal)

WAIT STATE OFF

6. You are now ready to install the board in your computer. Open your PC (after

turning off the power) and install the board. After the board is installed and the

computer is closed up, turn the power back on.

7. Run InstaCalTM again, and at the main menu select Test.

a. Select the board you just installed

b. Select Internal Test

c. The internal control registers of the board will then be tested. If this test

is successful, your board is installed correctly. If not, you likely have

a base address conflict, or have the base address switch set incorrectly.

Please refer to the next chapter for more information regarding selecting

and setting the base address.

d. If the Internal Test is completed successfully, you may want to check

that the I/O pins are working correctly. To check this select

External Test and follow the instruction provided. This will

require the use of an ohmmeter.

5.2 FORM C RELAYS (standard versions)

Shown here is the schematic for a form C relay as used on the standard CIO-

RELAY08, 16, 24 and 32.

The form C relay has a COMMON, normally open (NO) and normally closed (NC)

contact. When a 0 is written to the output, the common and NC are in contact. When a

1 is written to the output the common and NO are in contact.

5.3 FORM A RELAYS (/M versions)

Shown here is the schematic for a form A relay as used on mercury wetted (/M)

models.

The form A relay has COMMON and normally open (NO) connections. When a 0 is

written to the output, the common and NO are disconnected. When a 1 is written to

the output the common and NO are in contact.

3 HARDWARE INSTALLATION

3.1 Mercury whetted (/M) board special considerations

The Mercury whetted boards must be mounted in the computer such that they will

remain within 30 degrees of vertical. Note that installation of these boards in most

tower computer cases will require the tower be rested on its side for proper operation.

3.2 BASE ADDRESS

The base address switch controls the I/O location where the CPU can access the regis-

ters of the CIO-RELAY board.

The factory default is 300H (768D).

If you have a board installed at address 300H, you will have to choose a new address

from those available on your computer. You may use the list of PC I/O address

assignments found on the following page and add notes about the boards you have

installed in your computer.

Choose a new base address from those available and set the switch using the guide

below. Please note that the switch shown below is for the CIO-RELAY08 and CIO-

RELAY16 boards. Since the CIO-RELAY32 and CIO-RELAY24 board require 4 I/O

address, their base address switch does not provide switch 2. All other settings are

identical.

If address 300H is available on your computer, we recommend that you select it. for

your board. The software examples are written for base = 300H.

3.3 WAIT STATE

There is a wait state jumper on CIO-RELAY series boards. The factory default is

wait state disabled. You will probably never need the wait state because PC expan-

sion slot busses are limited to 8 or 10 MHz.

If you were to get intermittent operation from your CIO-RELAY board, you may try

enabling the wait state to see if that solves the problem.

CIO-RELAY24 and CIO-RELAY32 Connector

This connector is the center of the board. The connector for relays 0 through 15

is the connector that is closest to the computer back-plate. PINS corresponding

to relays 24 through 31 are not connected on the RELAY24 version.

The form A relays used on the /M versions

have NO and COM connections only!

WARNING!

High voltages will be present on the CIO-RELAY boards when you

have connected high voltage inputs or outputs to the CIO-RELAY

connector. Use extreme caution! Never handle the CIO-RELAY

when signals are connected to the board.! DO NOT REMOVE

THE PROTECTIVE PLATES FROM THE CIO-RELAY.

5 CONNECTING TO RELAYS

5.1 I/O CONNECTOR DIAGRAMS

The CIO-RELAY08 and CIO-RELAY16 boards use a single 50 pin connector for sig-

nal interfacing. The CIO-RELAY24 and CIO-RELAY32 use two 50 pin connectors.

The pin-outs of the connector are shown here.

CIO-RELAY08 and CIO-RELAY16 Connector

PINS corresponding to relays 8 through 15 are not

connected on the RELAY08 version. The form A relays used

on the /M versions have NO and COM connections only!

WARNING!

High voltages will be present on the CIO-RELAY boards when you

have connected high voltage inputs or outputs to the CIO-RELAY

connector. Use extreme caution! Never handle the CIO-RELAY

when signals are connected to the board.! DO NOT REMOVE

THE PROTECTIVE PLATES FROM THE CIO-RELAY.

4 PROGRAMMING

The CIO-RELAY boards are easy to program. Eight bit registers located at the base

address and the base address plus an offset are written to control relays or can be read

to determine the state of relays.

In addition to direct I/O programming, the boards are fully supported by the powerful

Universal Library program as well as most third party application programs.

4.1 DIRECT I/O REGISTER PROGRAMMING

The CIO-RELAY family uses between one and four I/O addresses. Each address con-

trols 8 relays and the relays are controlled by writing to these registers. The base

address maps of the CIO-RELAY boards are shown below.

BASE ADDRESS Relay 0-7 Read/Write

BASE + 1 Relay 8-15 Read/Write (RELAY16, 24, 32)

BASE + 2 Relay 16-23 Read/Write (RELAY24, 32)

BASE + 3 Relay 24-31 Read/Write (RELAY32 only)

The registers are written to and read from as a single 8 bit byte. Each bit controls an

output (write) or represents the state of a relay (read).

All registers are read left to right. The leftmost bit being the most significant bit. Fol-

lowing this format bit 7 of BASE+0 corresponds to relay 7 and bit 0 to relay 0.

To construct a control word, use the following table:

801287406462032510164883 442 221 110 HEX VALUEDECIMAL VALUEBIT POSITION

For example, to assemble the control byte that will turn on relays 0. 1. 3. 5 and 7 we

can see from the chart below we need to write decimal 171 (hex AB):

171AB 111111OP0 212212OP1 004004OP2 818818OP3 00160010OP4 3213220120OP5 00640040OP6 128112880180OP7 WEIGHTON=1DECIMALWEIGHTON = 1HEXRELAY

4.2 PROGRAMMING NOTES

WRITE = CONTROL: Write a byte to the register to control the relays. A one in the

relay bit position turns the relay on.

READ = STATUS: Read the status of the relay control register. A one in the relay

bit position indicates the relay is on.

ON & OFF for FORM C RELAYS:

On means that FORM C relay common is in contact with the Normally Open contact.

Off means that FORM C relay common is in contact with the normally closed contact.
