Additional Relay Outputs
If more relay outputs are required, MRO 8 TS modules are used together with the MRC TS module
(mounting rail installation). Remember that the first 8 switching outputs of the first MGO module
in the system are permanently assigned to the common alarms. Thus the first MRO 8 TS module
which is connected by way of the MRC TS module to the first MGO module in the system is always
assigned to the 8 common alarms. The connection of the MRO 16 TS module provided for redun-
dant systems is described in Chapter 13.
Fig. 125 Connection diagram of the MRC TS and MRO 8 TS Modules
NOTE: The GND of the Bat, Int, and Ext connections of the MRC TS module must be connected
to the GND of the SUPREMA supply voltage.
The MRC TS module is connected via connector A by means of a 40-way screened ribbon cable
to the MUT module plugged into the rear of the rack. The MUT module establishes the connection
with the MGO module plugged into the rack (Chapter 10.4). MRO 8 TS modules Nos. 1-5 are con-
nected to the MRC TS connector 1-5 by means of a 20-way ribbon cable. In addition, the supply
voltage for the relays must be connected to the terminals Bat, Int, and/or Ext.
As an option, a switch can be connected to the Inhibit (Lock) terminal for the purpose of inhibiting
the relays. (Chapter 10.3).
MRC TS Module, Relay Connection Module
This module is used when relay modules for mounting rail installation remote from the rack are
used. Up to 5 TS relay modules (MRO 8 TS) are connected by way of an MRC TS module. It is to
this module that the relay power supply and the ribbon cable required for the control of the relays
by the MGO module are connected. The MGO module is connected to the MRC TS module with
a 40-way ribbon cable and a rack mounted MUT module.
The power supply to the relays must be provided by appropriate connections on the MRC TS mod-
ule. Also note the following points:
The power supply concept of the MRC TS module must agree with that of the rack (assignment
of the External/Internal/Battery terminals must agree).
When different voltage supplies are used for the MRC TS module and the associated rack, the
GND terminals must be connected together, otherwise the relays will not switch.
