Description of the System

MIB Module (Interconnection Board)
This circuit board handles the system wiring of the rack. There are 15 slots for modules. Some of
these slots are reserved only for certain module types. The modules installed in the rack can be
connected by plugging in “terminal modules” (MAT module, MUT module, etc.) at the rear of the
rack. Each rack clearly indicates which module can be used in each slot.
MST Module (System Terminals)
MAT Module (Analog Terminal Unit)
MAT Module TS (Analog 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.)
• Rack rear-panel wiring for 2 x MCP modules, 2 x MDA modules,
8 x MAI/MGO/MBC modules, and additional 2 x MGO/MBC modules
• Power supply for all modules (EXT, INT and BAT)
• Connections for 3 x 24 VDC power supplies, screw terminals (4 mm
2
)
• Provision for uninterruptible 24 VDC system power supply
• Data transfer between the modules over the CAN bus or the SPI bus
• 2 System Failure Relays, 1 changeover contact, 3 connection terminals
• DIL switch for CAN rack ID, CAN bus termination, system behaviour (FreeA/B) and
Baudrate
• 5 dedicated slots for 2 x MCP, 1 x MDC+MDO, 2 x MDA modules
• 10 undedicated slots for MAI (only 8), MAO, MGO, or MBC modules etc.
• Electrical connection of the inserted modules
• Terminal modules (MST, MAT, MUT etc.) are plugged into the rear of the MIB module
• Connection module for system expansions.
• Installed at the rear of the rack.
• Ports MST10: 2x CAN A, 2x CAN B, RS 232-A (PC operation), RS 232-B (serial printer, out-
put from messages), RS 232-C (unused), alarm reset (RES), horn reset (HACK), relay in-
hibit (LOCR), password key switch (PSW).
• 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.
