Product Overview
The Honeywell 900RTR-H001 HC900 Relay Output RTP Module is a Remote Terminal Panel (RTP) interface module designed for the Honeywell ControlEdge HC900 Distributed Control System (DCS).
It is used as an intermediate interface between HC900 relay output modules and field wiring terminals, providing safe, organized, and maintenance-friendly relay signal distribution. The module improves wiring reliability by integrating individual channel fusing, load disconnect switches, and structured terminal layouts.
This makes it especially suitable for industrial automation systems requiring high-density relay switching with strong maintainability and protection features.

Function and Working Principle
The 900RTR-H001 operates as a relay signal termination and protection interface layer within HC900 systems.
Working principle:
- Relay Signal Reception
Receives switching outputs from HC900 relay output modules. - Field Terminal Distribution
Routes relay signals to external field devices (valves, motors, alarms, etc.). - Per-Channel Protection
Each relay channel includes an individual fuse to protect against overload or short circuits. - Load Disconnect Function
Built-in switches allow safe isolation of field loads during maintenance. - Signal Isolation
Ensures electrical separation between control system and field devices. - System Integration
Connects to HC900 controller via dedicated system wiring harness.
