D1000 Galvanic Isolators Series Information

View all models

G.M. International Din-Rail mount Intrinsic Safety Galvanic Isolators provide the most simple and cost effective means of implementing Intrinsic Safety into your Hazardous Area applications.

High Packing Density

  • High channel density result from innovative circuit design using advanced surface mount components.
  • Ultra slim 4 channels 22,5 mm wide DIN rail mounting modules.
  • 6 mm per channel.
  • 176 I/O channels per meter of DIN rail.
  • Single, dual or quad channel models

High performance

  • High Signal transfer accuracy and repeatability.
  • Advanced circuitry provides low heat dissipation, ensuring modules run cool despite their high functionality
  • Low power consumption.
  • SMD manufacturing to maximize long, reliable life.

Wide Functionality

  • Wide Range of digital switch and analog I/O.
  • Relay contacts rated for 2 amp. to directly switch high loads.
  • Three port galvanic isolation to eliminate noise, ground loop problems and to provide Intrinsic Safety without a high integrity safety earth connection (necessary when using Zener Barriers).
  • Line Fault alarm detects open or short circuit of field cables
