5. Installation
5.5.2 Systems with Decentralised Recording of Measuring Values (Satellites)
To reduce the installation cost for systems with large distances between the sensors and alarms
the SUPREMA evaluation unit, for recording of measuring values as well as control of alarm
means can be carried out near the sensors.
This can be achieved by having a SUPREMA rack (rack with MDO module) installed in a
control station, and a satellite SUPREMA rack (rack-E without MDO-10), equipped only with
with measuring points and/or outputs, installed in the field. Both racks communicate with one
another via the CAN Bus.
This means that instead of up to 64 sensor cables, only one CAN bus cable has
to be connected.
Note: At distances >20 m, a CAN bridge has to be interposed. (see section
5.5.2.1 SUPREMA CAN Bridge CBM)
Examples of Satellite Applications:
With one satellite:
