Product description

iC-GE100 is a PWM driver for inductive loads, such as relay coils, solenoid valves and other inductive loads.

The setpoints for the coil's energising and hold current are pre-set by means of external resistors RACT and RHOLD. These currents can be set in a range from 10 to 100 mA. The iC-GE100 switches from energising to hold mode after 50 ms provided that the set energising current has been reached.


  • Current control for inductive actuators at 24 V (10 to 36 V)
  • Power saving and power dissipation reduced switching
  • Individual setting of energising and hold current
  • Contact conserving switching of relays synchronous to the mains
  • High efficient current control up to 100 mA
  • Monitoring of coil current, supply voltage and temperature
  • Shutdown with overtemperature and undervoltage
  • Status indication via LED or logic output
  • Fast demagnetising with 15 V countervoltage


  • PWM drive for inductive loads (e.g. 6/12 V relays, electrovalves) from 24 V
  • Relay low-/high-side switch
