About the ABB CP-A CM 1SVR427075R0000 control module

1. Integration with Redundancy Unit: The CP-A CM module is specifically designed to be pluggable onto the CP-A RU redundancy unit. This integration allows for seamless monitoring and control of the redundancy unit’s operations.

2. Voltage Monitoring: The module monitors both channels of the CP-A RU redundancy unit for undervoltage conditions. It is equipped with threshold values that are adjustable from 14 to 28 volts, providing flexibility in voltage monitoring based on specific application requirements.

3. Relay Outputs: The CP-A CM module features two relay outputs, with one relay output dedicated to each monitored input or channel. These relay outputs indicate the presence of input voltages from the redundancy unit.

4. LED Indicators: The module uses LEDs to indicate the status of the input voltages. When the corresponding voltage exceeds the adjusted threshold value, the green LEDs (IN 1”, IN 2”) glow. Additionally, a green LED (OUT”) illuminates if the output voltage is higher than 3 volts.

5. Safety and Compliance: The CP-A CM module meets various safety and compliance standards, including H UL 60950, CAN/CSA C22.2 No. 60950, GOST, and CE marking, ensuring its suitability for use in a wide range of applications.
   
   Operating mode
   Parallel operation, true redundancy with decoupling provided by the CP-A RU
   Redundant circuits are used to increase the operational reliability and eliminate power supply outages. Events that can
   cause a power supply failure include: incorrect wiring, blown fuses, or failure of a single power supply. If a fault event
   occurs (called initial fault) in the first power supply circuit, power to all loads is then supplied by the second (redundant)
   power supply. For this reason, both power supplies must be sized to handle the total current requirement of all loads. The
   primary and the redundant power supplies are decoupled from one another by the CP-A RU unit.
   It switches from the primary to the redundant supply after a fault. It decouples the output of the failed power
   supply from the redundant supply preventing the initial fault from shorting or compromising the redundant supplies’ output.
   In this way, uninterrupted supply of power to all loads is guaranteed.
   When available, the two power supplies should be connected to different input voltage phases, to avoid loss of power
   caused by a blown fuse on the primary side of the power supplies.
