3. Description of the System
• 0 ... 20 mA output drivers, measurement signal outputs (galvanic isolated from system)
Measurement signal output: 4 ... 20 mA
Measuring range overshoot: 22 mA
INHIBIT: 3.0 mA
Signal failure: 3.2 mA
Fail dependent of Free A/Free B (see Tab. 5-8)
• Maximum load: 500 Ohm
• Data transmitted from the MDO module via the CAN bus
• The System Failure Relay is activated when a processor error occurs
• Euro card with a 96-way connector
3.6.5 Power Supply, Bus Connections, Connecting Technique
• MSP Module: System Power Unit
(power supply unit, 85 ... 253 VAC/24 VDC)
• MIB Module: Interconnection Board
(rack, bus circuit board)
• MST Module: System Terminals
(RS 232, RES, ACK, LOCK, CAN)
• MAT Module: Analogue Terminal Unit
(terminals for sensors on the rack)
• MAT TS Module: ANALOGUE TERMINAL UNIT
(terminals for sensors on the rack)
• MUT Module: Universal Terminals
(40-way ribbon cable connection)
MSP Module (System Power Unit)
• Rack power supply unit, 150 VA
• Wide range input, 85 ... 265 VAC
• Output voltage, 24 VDC
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 intended 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.
• Rack rear-panel wiring for 3 x MCP modules, 2 x MDA modules, 8 x MAI modules, and
2 x MGO 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
• System Failure Relay, 1 changeover contact, 3 connection terminals
• DIL switch for CAN rack ID and Baud rate
