Operation Manual SUPREMA
3. Description of the System
• 5 dedicated slots for 3 x MCP, 2 x MDA modules
• 10 undedicated slots for MAI, MAO, or MGO modules, etc.
• Electrical connection of the inserted modules
• Terminal modules (MST, MAT, MUT, etc.) are plugged into the rear of the MIB module
MST Module (System Terminals)
• Connection module for system expansions.
• Installed at the rear of the rack.
• Ports: CAN A, CAN B, RS 232 (PC), RS 232 (laptop operation) printer, alarm reset, horn
reset, relay inhibit, key switch (password).
MAT Module (Analogue Terminal Unit)
• Terminals for sensors, 0 ... 20 mA outputs, etc. (1.5 mm
2
).
• 8 inputs, each with 5 terminal connections.
• Solder bridges for the 3-wire connection of passive catalytic sensors.
• Up to 4 MAT modules can be provided for the connection of up to 32 sensors.
MAT Module TS (Analogue Terminal Unit)
Similar to the MAT module but for installation on C-type or top-hat rail separate from the rack.
A 40-way ribbon cable and a MUT module are required to connect it to the rack.
MUT-Module (Universal Terminals)
This module is used to connect modules which are separate from the rack (MRC-TS module,
MAT-TS module, etc.) to the module inserted in the rack by means of a 40-way ribbon cable.
(Adapter plug, 96-way to 40-way.)
Relay Outputs
Up to 512 switching outputs can be controlled by the system via MGO module driver cards (40
open collector drivers each). These switching outputs can be used to drive relays, magnetic
valves, contactors, lamps, LEDs (24 VDC/0.3 A). If relay outputs are required, various relay
modules can be used:
• MRO-8 module: 8 common alarm relays on the rack
• MRC-TS module: relay connection, actuation of 5 relay modules
• MRO-8-TS module: 8 relays, installed on mounting rail
• MRO-16-TS module: 16 relays, redundant layout, installed on mounting rail
MRO-8 Module (Relay Output Unit: Common Alarms)
This module must be used when relays alone are required for actuating common alarms and
installation is to be accomplished directly in the rack. The module can be plugged directly into
the MIB module (rear of the rack). It then makes the 8 common alarm relays available. If more
relay outputs are to be provided, then MRO-8-TS modules are to be used together with the
MRC-TS module (installed on the mounting rail). Each relay has a changeover contact connected
to screw terminals.
