3. Description of the System
• Display of the system status (common LEDs for alarms, signal failure, system failure,
inhibit)
• PC control (data display, printer control)
• System clock (RTC) with backup battery
• 3 x RS 232, electrically isolated (laptop/PC/printer interface)
• System Failure Relay is activated when a system malfunction occurs

(source 0 ... 20 mA/500 Ohms load/electrically isolated from system power supply)
MGO Module (General Output Unit)
The MGO module is provided to display alarm messages or other control signals. It receives
the switching data for the relay output drivers from the MCP module via the CAN bus. The
output is protected against short-circuits and overloads. Driver outputs 1–8 of the first MGO
module present in the system are used to control the 8 common alarms (Alarms 1–4, horn,
signal failure, inhibit, power).
In redundant versions of the system, each of the two MGO modules controls 8 relays on the
MRO-16-TS module (16 common alarm relays/redundant), the working contacts of these relays
are connected in series.
• 40 relay driver outputs for relays, contactors, magnetic valves, lamps, or LEDs
(24 V/0.3 A).
• The data is transmitted via the CAN bus from the MCP module.
• The System Failure Relay is activated when a system error occurs.
• Euro card with a 96-way connector.
MRC-TS Module (Relay Connection) / MRO-TS Module (Relay Output)
The output signals of the MGO module are sent over a 40-way ribbon cable from the MUT
module to the MRC-TS module and from there over 20-way ribbon cables to the MRO-TS
modules and the relays.
MAO Module (Analogue Output)
This module is used when analogue outputs are installed in the system. Each MAO module
has 8 analogue signal outputs for 0(4) ... 20 mA current loops. The outputs are assigned directly
to the signal inputs. (measuring point 17 = analogue output 17).
