
Profibus module (PBM)

Analog input extension module (AEAM)

LCD copy module

MIMIC module
Each RBM provides eight relays to be freely allocated. The REM allows the
addition of eight relays with a minimum of space.
The AAM provides either 4-20 mA or 0-10 V outputs.
The AEAM can be used in combination with the AEM to connect smoke
detectors at WinPro

/ MX62.
All measured values and informations can be displayed with the LCD module
and stored by a data logger.
2.1. Description of Modules
2.1.1. Controller module (CM)
The CM is the central control unit of the system for all 64 channels of
maximum configuration. Two 16 bit micro controllers process the signals
of the input modules redundantly.
The status of the relays and the output signals are transmitted to the relay
and analog output modules by a redundant bus.
Another bus transmits the signals to the LCD and LED module. For safety
control the CM also contains relays to signal system errors, emergency
operation and service mode.
By means of an RS232 interface, the entire system can be configured and
all data can be visualized on a PC.
A Centronics interface is available for connection of a printer.
2.1.2. Analog input module (AEM)
The detectors are connected to the AEM. Each module accommodates up
to eight detectors with 4-20 mA signal output and provides an additional
RS485 interface per channel.
By this interface, communication can be established in service mode
between a PC, connected to the CM, and the respective digital detector.
Up to eight AEM can be connected to the CM. An address between 1 and
8 is allocated to each module by rotary switch.
