Current saving module

The current saving module is used to reduce the coil current of relays and contactors at a max. load current of 1.5A. The coil current is reduced to a nominal current of 95% - 5% after a defined time by pulse width modulation.

  • Load current max. 1.5A
  • Load current reduction 95% - 5%
  • Supply voltage 24V DC (12 ... 32V DC)
  • Control voltage 24V DC (12 ... 32V DC)
  • PWM switch-on time 100/200/500/1000ms
  • 2 channels per module
