Honeywell 900G01-0001 | Digital Input Module

Overview

The Honeywell 900G01-0001 Digital Input Module is a contact closure type digital input module designed for industrial automation applications. It is self-powered, supplying 15VDC to external switching hardware to close the input loop. When an external circuit is closed, current flows to the input, establishing an ON state. The controller logic allows for state inversion if needed.

Key Features

• Self-Powered Input: Provides 15VDC to external switching circuits.

• 16 Single-Ended Inputs: Supports contact closure detection.

• LED Status Indicators:

  • Green LED per channel for ON state indication.

  • Green Blinking LED for module scanning.

  • Amber Blinking LED for forced channels.

  • Red LED for diagnostic errors.

• Fast Response Times: 4ms (OFF to ON), 6ms (ON to OFF).

• Four Common Terminals: Simplifies field wiring.

• Galvanic Isolation: Ensures electrical separation between field wiring and the module backplane.
