Add-On Modules

The DRML1 Load Monitoring Module is an add-on module designed to be plugged into Panel Mount PM22 Series and DIN Rail Mount DR22 Series contactor configuration models to provide complimentary monitoring functions.

This module can detect partial or total load failure of up to 8 loads, for a total current ranging from 1.2 Amps up to 50 Amps at 600 VAC, which makes it an excellent solution for quality supervision of heating systems.

Additional features of the DRML1 module include:
  • Selectable max current rating: 20 Amps or 50 Amps
  • Selectable alarm delay (0.1 sec, 1 sec, 5 sec)
  • Minimum current for single load: 150 mA
  • Alarms detected: undercurrent, overcurrent, open mains voltage, SSR fault
  • Alarm output: PNP open collector, 6-28 VDC, 100 mA
  • Up to 128 modules can be connected in parallel
  • Multicolor LED with input status and alarm indication
