The Honeywell 900G03-0102 is a high-density, 32-channel digital input module engineered for the ControlEdge HC900 process controller system. This module is designed to interface the controller with standard 24 VDC discrete field devices, such as pushbuttons, limit switches, proximity sensors, and relay contacts. By packing 32 input points into a single slot, it offers an exceptionally efficient solution for systems requiring extensive discrete monitoring while minimizing overall control cabinet footprint.
Features
High-Density Channel Array: Provides 32 distinct discrete input channels in a single slot to drastically maximize rack space utilization.
Group Galvanic Isolation: Segregates input channels into isolated groups to protect internal controller logic from external electrical noise and ground loops.
Onboard LED Diagnostics: Features individual front-panel light-emitting diodes to provide immediate visual confirmation of the ON/OFF state for every channel.
Configurable Input Filtering: Supports programmable software filter times per channel to eliminate contact bounce and prevent false signal triggering.
Hot-Swappable Functionality: Enables safe module replacement under full system power, keeping operations active during routine maintenance.
