CP-A CM control module Section 3 Modules
54 M&I – AC 900F Controller
For detailed information on the wire stripping length, please refer to Section 9,
Technical Data. Left input terminal + - for channel 1, right input terminal + - for
channel 2.
Output side [OUTPUT + + - -]
Rate the lines for the maximum output current or provide separate fuse protection.
To minimize voltage drops, a maximum cable cross-section should be selected.
Observe the polarity!
CP-A CM control module
The CP-A CM control module can be plugged to the CP-A RU redundancy unit.
This module features threshold values adjustable within a range of 14 to 28 Volt and
two relay outputs and is designed for monitoring both channels of the energized
redundancy unit.

Function
The CP-A CM control module indicates the supply of both input voltages at the CP-
A RU by means of LEDs and energized output relays.
The output relay threshold values can be set between 14 und 28 V for each channel
separately. If the voltage in one of the channels falls below the set threshold value
