4.0 BOARD DESCRIPTION

User’s Manual Page 2

5.0 SPECIFICATIONS

5.1 Power Requirements

Regulated +5VDC@ 500mA is required to power this board.

WARNING

Check the polarity and voltage of the external power source and connect the 5VDC and

GND. Overvoltage or reverse-polarity power applied to these terminals can cause

damage to the board, and/or the power source.

6.0 POWER TERMINAL

User’s Manual Page 3

6.2 Enable pin.

The card must be provided with a 5VDC signal to enable operation. This feature has been added

to externally control the status of the outputs. An external switch or a Safety Charge Pump can

be added to provide the enabling signal. When the enable signal is not present, output signals

sent high impedance state. If this function is not required, a jumper can be placed between +5vdc

and the EN terminal. It has an internal 4.7kOhm pull-down resistor

7.0 LED INDICATOR

The power LED lights to indicate that the system is ready but disabled. When Status

LED, (Green LED) lights, it indicates that the system is enabled.

8.0 CONFIGURATION JUMPERS

8.1 Using the COM configuration jumper

There is a jumper that allows you to select +5VDC or GND for the COM pins.

1-2: COM= GND 2-3: COM= +5VDC

8.2 Using the Pins 2-9 direction jumper

There is a jumper to select the pins 2-9 direction.

1-2: OUTPUTS 2-3: INPUTS

User’s Manual Page 5

8.3 Using the Pull-up or Pull-down selection jumper for pins 2-9.

Jumper allows to change the input configuration for 2-9. Using the Pull-up or Pull-down

selection jumper for pins 2-9 the input voltage is pulled through a 4.7Kohm resistor to up

or down in this way:

1-2: PULL-DOWN 2-3: PULL-UP

8.4 Using the Pull-up or Pull-down selection jumper for pins 10, 11,

12, 13 and 15.

Jumper allows to change the input configuration for pins 10, 11, 12, 13 and 15. Using

the Pull-up or Pull-down selection jumpers for those pins will pull them up or down

through a 4.7Kohm resistor:

1-2: PULL-DOWN 2-3: PULL-UP

9.0 FUNCTIONAL BLOCK DIAGRAMS

9.1 Bidirectional pins simplified block diagram

Fig. 1 Simplified functional block diagram for the 2-9 pins.

A Pull-up or Pull-down selection jumper allows selecting the configuration for the all

bidirectional pins (2-9) when they are set as inputs.

9.2 Dedicated Inputs simplified block diagram

Fig. 2 Simplified functional block diagram for the inputs.

A Pull-up or Pull-down selection jumper allows selecting the configuration for the all

dedicated inputs (pins 10, 11, 12, 13 and 15).

10.0 WIRING DIAGRAMS

While this board supports only TTL +5VDC signals, different kind of sensors, switches

using different voltages can be connected using the diagrams that follow:

Note. This board has two possible inputs banks, (bidirectional pins: 2-9) and (dedicated inputs: pins 10, 11,

12, 13 and 15), and all the inputs of the same bank have the same configuration. The below wiring diagrams

are an example, any input can be used for the connections.

Note. The bellow wiring diagrams require setting the inputs to use pull-down resistor.

10.1 Connecting Switches or push button.

10.2 Connecting NPN sensors.
