Description

Designed for seamless integration with the HC900 controller platform, the 900G02-0202 facilitates the precise acquisition of discrete binary states from field-level sensors, switches, and contacts. This digital input module accommodates 16 independent input channels operating at a nominal 24 VDC threshold. It processes raw ON/OFF signals from limit switches, proximity sensors, pushbuttons, and auxiliary relays directly into the control processor database, ensuring dependable status updates for interlocking, safety monitoring, and sequencing logic.

The module features exceptional galvanic isolation to shield internal logic circuits from field-side electrical disturbances, surges, and common-mode noise. Status LEDs on the front panel provide real-time visual feedback for diagnostic verification. Engineered for high-density environments, this module minimizes cabinet footprint while maintaining superior thermal dissipation profile across standard operating ranges.

Features

16 high-density digital input channels configured for 24 VDC sinking or sourcing inputs.
Individual channel LED indicators on the faceplate for rapid loop diagnostics and status verification.
Robust optical isolation protecting backplane control circuitry from field-side electrical transients.
Hot-swappable architecture allows safe module insertion and removal without disrupting active controller backplane operations.
Configurable software input filters to eliminate contact bounce and high-frequency noise.

Applications

Burner management systems (BMS) and industrial combustion control loops.
Water and wastewater treatment plant monitoring.
Boiler system safety interlocks and auxiliary equipment tracking.
Chemical processing and refinery auxiliary sequence control.

Installation Guidelines

Align the module carefully with the card guide rails of the HC900 rack chassis and slide firmly inward until the backplane connector is fully seated.
Secure the upper and lower retaining screws to protect the module from vibrational displacement.
Avoid routing 24 VDC digital input field wiring in parallel close to high-voltage AC power lines to prevent electromagnetic coupling.
Utilize the designated terminal blocks designed for the HC900 system to ensure correct wiring pinout and strain relief.
