Honeywell 900G02-0102 16 Channel 24 VDC Digital Input Module

Configured for discrete signal acquisition in Honeywell HC900 control systems, the Honeywell 900G02-0102 (900G02-0102 16 Channel 24 VDC Digital Input Module) provides direct electrical monitoring of field switches, sensors, and digital status devices. The module converts field-state transitions into controller-readable input data for process monitoring and logic execution within HC900 automation platforms.

Hardware Specifications

Channel-to-Channel Isolation and Digital Signal Acquisition

The 900G02-0102 module provides sixteen independent digital input channels for acquisition of field-state information. Input channels are designed to receive 24 VDC discrete signals from industrial devices including limit switches, pushbuttons, proximity sensors, relay contacts, and auxiliary equipment status outputs.

The module incorporates 500 VDC isolation to separate field-side wiring from controller electronics. This isolation assists in reducing the effects of electrical disturbances and supports stable signal acquisition in industrial control environments.

Input state changes are transferred to the HC900 controller for logic processing and supervisory functions.

HC900 System Integration and I/O Density

The 16-channel architecture provides high input density within a compact module footprint, enabling efficient integration of multiple field devices into the HC900 platform.

Fast input response characteristics support monitoring of field device status changes with a specified response time of less than 5 ms. The module operates from standard 24 VDC instrumentation power and is intended for use in distributed control and process automation applications.

DIN-rail mounting simplifies deployment in control cabinets and remote I/O installations while maintaining compatibility with HC900 control architectures.
