Terminal Modules (Accessory)
7.2.4
Installation
1 Secure the terminal module to a mounting rail.
2 Connect the 37-pole plug connector of the terminal module with the “Analog and digital
I/O” plug connector of the operating unit. To this purpose use the special connection
cable (order no.
→ P. 200, §16.10.6 ):

Connect the “Connecting module” plug connector to the terminal module.

Connect the “Remote unit” plug connector to the operating unit.
3 Connect a 24 VDC power supply to terminal strip X2 ( → P. 72, Fig. 23 ).
4 Configure the terminal module as required ( → P. 74, §7.2.6 ).
5 Establish the signal connections accordingly ( → P. 76, §7.2.7 ).
7.2.5
Function of the relay switching contacts
Switching logic
Load capacity

Subject the switching contacts of terminal module 2 to a load of 24 V/500 mA max.

Only connect inductive loads if suppressor diodes (free-wheeling diodes) are provided.
7.2.6
Configuration options (jumper)
Connection of the analog outputs
In the standard configuration the analog outputs on terminal strip X20 are available; can,
however, also be connected to X10. The jumpers J4 and J5 serve for configuration
purposes:
The connector pin assignment of the connection cable are not identical.

Do not confuse the ends of the connection cable.
Logical function condition Condition of the relay switching contact
Enabled Closed
Disabled Open
Power supply failure/switched off Open
When the mains voltage is switched off, the alarm signals of the operating unit
are in the “Alarm” status.
NOTICE:
Inductive loads (e.g. relays, solenoid valves) can severely damage the relay
switching contacts if the induced voltages are not discharged through
suppressor diodes.

With inductive loads: Check whether suppressor diodes are installed.

If this does not apply: Install separate suppressor diodes.
Table 6 Jumper configuration for the analog outputs of terminal module 2
Use the analog output on X20 on X10
1 Analog output 1 “Measured value” J4 bridged J4 open
2 Analog output 2 “Reference value” J5 bridged J5 open
The analog outputs are potential-free towards the other electronic
components, but not towards one another (joint minus pole).
