MRO 8 Module: Relay Assignment
MRC TS Module (Relay Connection Module)
This module is used when relay modules separate from the rack are installed on a mounting rail.
An MRC TS module is used to connect up to 5 TS Relay modules. The relay power supply and
the ribbon cable, which are required for the control of the relays by the MGO module, are attached
to this MRC TS module. It is possible to control 5 MRO modules (with alternatively 8 or 16 Relays
each). The MRC TS module is connected to the MGO module over a 40-way ribbon cable (2 for
the redundant version) and a rack mounted MUT module. In the redundant version 2 MGO mod-
ules are used and are connected via 2 MUT modules and 2 ribbon cables to the MRC TS module.
MRO 8 TS Module (Relay Output Unit: Non-redundant)
This module is provided when not only common alarms but also other messages are required.
Each relay has a changeover contact (230 VAC/3 A). The module makes 8 relays available, each
with its own changeover contact. The relays are controlled by an MGO module, operating via the
MRC TS module.

• Connections for the relay power supply (3 x 24 VDC)
• Connections for relay inhibiting
• Bridge (BR1) for the selected type of inhibit (normally energised/normally de-energised)
• The module is controlled by an MGO module operating via the MRC module.
• 8 relays for alarms or control functions.
• 1 changeover contact per relay connected to terminals.
• The relays can be inhibited by the LOCK function (no alarm). The LOCK function can be
controlled via the MRC TS module.
