10208/2/1 Honeywell | Fail-Safe Controller Relay Card

Honeywell 10208/2/1 Fail-Safe Relay Output Module FSC System

Product Overview

The 10208/2/1 (10208/2/1) is a high-integrity Relay Output Module designed for use within the Honeywell Fail-Safe Controller (FSC) system. This module provides galvanic isolation and robust switching for safety-critical final control elements, such as emergency shutdown (ESD) valves, fire pumps, and motor starters. Unlike standard digital outputs, the 10208/2/1 (10208/2/1) utilizes dry contact relays to ensure a physical break in the circuit during a safety demand or system failure, adhering to strict SIL (Safety Integrity Level) requirements.

While some legacy documentation occasionally cross-references varied part numbers, the 10208/2/1 (10208/2/1) specifically serves the Honeywell FSC architecture, providing reliable de-energize-to-trip functionality. Its design incorporates redundant internal circuitry and diagnostic feedback to monitor the health of the relay coils, ensuring that the safety function is performed even if a single component fails.
