Type PowerPlex® Compact Module CM500

~ 137 mm


The PowerPlex® Compact Module is designed for DC 12 V and DC 24 V on-board power supplies for recreational vehicles and boats. It offers eight multi-functional inputs that can be configured as digital or analog input, and 14 load outputs.

The digital inputs allow the connection of switches, push buttons or point level indicators. The analog inputs can be used for current, voltage, temperature and/or level measurement. To change the direction of rotation of a DC motor, e.g. for a step, two outputs can be used as H-bridge.

Product Features:

  • Galvanic isolation of the CAN interfaces
  • Multi-functional inputs
  • Configurable outputs (10 x 10 A, 4 x 3 A)
  • Software-controlled overcurrent protection with current measurement
  • Hardware-controlled safety disconnection
  • Self-protection of power transistors

Application examples:

  • Control and monitoring of DC loads
  • Control, dimming and monitoring of lights
  • Windshield wiper control
  • Motor control i. e. steps, lift beds, slide outs
  • Voltage measurement
  • Current measurement
  • Temperature measurement
  • Control of heating and air-conditioning systems
  • Fuel flow monitoring
  • Fuel tank level / remaining volume
  • Water tank levels / remaining volume
  • Pump control and monitoring
