4.1 Function of the Relay/Trigger/Analog Slide-in Module

The relay/trigger/analog slide-in module ES 500 RTA6 is a universal trigger output

interface for the data logger ALMEMO®500, featuring up to

10 input /output interfaces (standard 4 solid-state relays (normally open contact)

and 2 trigger inputs, optionally featuring further relays and/or analog outputs.

On request: up to 10 solid-state relays or 10 galvanically isolated analog outputs).

4.2 Requirements for the Use of the RTA6 Slide-in Module

The RTA 6 slide-in module can be used starting with software version

1.2.4 of the CPU card.

The measuring circuit boards must feature the revision number R3 or

higher. The revision number of the measuring circuit boards will be

displayed in the status display in the menu 3) Firmware (on the

running data logger press the right navigation key until the menu 3)

Firmware will be displayed. The revision number is listed behind the

measuring circuit board number (e.g.G00 R3)).

To be able to adjust the settings of the RTA6 slide-in module with the

ALMEMO®500 app, the software version of the app needs to be

V1.5.9 or higher.

4.3 Connections for Relay, Trigger, and Analog outputs

By default, the ports P0/1 and P2/3 are equipped with 4 solid-state relays normally

open (NO) contact (optionally change over (CO) contact) and port P8/9 is

equipped with 2 trigger inputs. The ports P4/5 and P6/7 can optionally be equipped

with analog outputs or with further solid-state relays.

4.3.1Relays

The output relays can directly be addressed via the data logger in case of an alarm

or via interface commands. The function of every relay can be configured

arbitrarily. The assignment of the limit value to the relay is programmable in the

sensor via the data logger.

By default, a short acoustic alarm will sound whenever a relay is activated. Using

inversion, the relay control can be set in such ways that the relays will normally pull

in and in case of alarm or power failure the relays will drop out.

In the following cases it is suggested to add a mains voltage /change over (CO)

contact relay (e.g. Phoenix PLC-RSC-24DC/21, 250V 6A):

-In case the current or voltage load is higher than 50 V, 0.5 A,

-For isolation purposes of the voltage side,

-For implementation purposes of an alarm in case of failure of the control

side (see image below)

4.3.2Trigger inputs

The trigger inputs P8 and P9 can be addressed via an optocoupler with a voltage

level of 4 V to 30 V. In case potential-free switching contacts are used, the

optocouplers must be wired-up according to the supply U+ and U- (see image

below). The trigger functions (starting or stopping a measurement) can be edge-

triggered or level-triggered . (see chapter 5.5.3 Set the Trigger Port Assignment).

4.3.3Analog outputs

Optionally a slide-in module can also be equipped with galvanically isolated analog

outputs that can feature the following signals:

Option

Output signal

Increase

OA 500-R02

0.000 V to +10.000 V

0.5 mV/digit

0.000 mA to20.000 mA

1 µA/digit

The output value normally corresponds to the measured value of a selectable

monitoring station. Alternatively it is possible that the analog value is preset as

control parameter via the interface (see chapter 5.5.4 Set the Analog Output Port

Assignment). The output signal can in any case be programmed as standard

output 0-10 V, 0-20 mA, 4-20 mA from arbitrary measuring range sections (see

chapter 5.5.4 Set the Analog Output Port Assignment).

5 How to use the RTA6 Slide-in Module

In case the RTA6 slide-in module was delivered together with the data

logger, the address of the RTA slide-in module is already preset and the

RTA slide-in module is plugged into a RTA appropriate slide-in location.

In case the RTA6 sot was delivered separately from the data logger

(e.g. because it was reordered), the address of the RTA slide-in module

must be set (see chapter 5.2 Set the RTA6 Slide-in module Address)

before the RTA6 slide-in module can be plugged into the data logger.

5.1 Connection of the Peripherals to the ALMEMO®

Clamping Connector

You can plug in ALMEMO®clamping connectors to the ALMEMO®sockets of the

RTA6-slide-in module, where previously the relay, trigger, or analog signals were

connected.

Never connect voltages higher than 50 V to a relay port.

Never connect voltages higher than 30 V to a trigger port.

Voltage and current outputs are mere output ports. Do not connect

any external voltage sources to these ports.

The relay, trigger, or analog signals must be connected to the provided ALMEMO®

clamping connector according to the following diagram:

5How to use the RTA6 Slide-in Module

- 10 –

5.2 Set the RTA6 Slide-in Module Address

→In case the RTA6 slide-in module is plugged into the data logger, remove the

RTA6 slide-in module from the data logger housing, see chapter 5.7

Remove RTA6 Slide-in module from the Housing of the Data Logger.

→Turn the coding switch until the slit of the small wheel of the coding switch

points to the desired number.

The addresses of the individual RTA slide-in modules must be coded

in ascending order from 00 to 03. The first RTA slide-in module must

have the RTA slide-in module address 00.

Several RTA6 slide-in modules must not have the same RTA slide-in

module address.

In the ALMEMO®500 app, the RTA slide-in module will be named A0

to A3, depending on the RTA slide-in module address 00 to 03.

5.3 Insert the RTA6 Slide-in Module into the Housing of

the Data Logger

!The data logger must be switched off.

!The data logger must be disconnected from the power supply.

For the RTA6 slide-in module use the slide-in location next to the

slide-in location of the CPU card and the measuring circuit boards

(from the left to the right). If you want to use several RTA6 slide-in

modules, insert the RTA6 slide-in modules (RTA6 slide-in module

address ascending from left to right) into the slide-in locations of the

data logger.

3. Insert the RTA6 slide-in module into the data logger housing.

4. Fasten the knurled screws of the RTA6 slide-in module.

➢The ON-LED lights as soon as the data logger is switched on.
