The Honeywell 900G02-0102 is a 16-channel 24 VDC digital input module designed for the ControlEdge HC900 controller system. It interfaces discrete field signals with the system rack, delivering signal processing and galvanic isolation between chassis ground and input channels.
Each channel on the 900G02-0102 digital input module monitors discrete state changes from field devices and reports channel status to the ControlEdge HC900 CPU or scanner module. An onboard microprocessor conducts parallel signal processing per module to maintain high-speed execution across backplane racks. The device features front-panel LEDs for channel and module diagnostics and interfaces with detachable Euro or Barrier terminal blocks or Remote Termination Panels.
