Honeywell 900G01-0202 Digital Input Module – Product Description

The Honeywell 900G01-0202 Digital Input Module provides reliable signal acquisition for HC900 Hybrid Controllers and ControlEdge HC900 systems. Each of its 16 channels reads digital states from field switches, relays, and sensors with excellent accuracy. Moreover, its robust galvanic isolation protects the controller and ensures stable operation in demanding industrial environments.

The module’s compact design supports modular installation, allowing engineers to expand system capacity without disrupting existing configurations. In addition, input circuitry is optimized for 24 VDC field applications, delivering consistent performance in factories, utilities, and mission-critical process plants. Its fast response times help operators capture real-time events and improve overall system visibility.
