Digital Output Module 8-Channel 24V | Honeywell FS-SDO-0824

Product Overview

The FS-SDO-0824 (Model: FS-SDO-0824) is a high-integrity safe digital output module designed for the Honeywell Safety Manager® and Experion® SIS platforms. This module provides 8 independent, short-circuit proof solid-state outputs tailored for safety-instrumented functions (SIF). It is engineered to drive critical field devices such as solenoids, valves, and actuators that require deterministic "fail-safe" de-energization.

As an "FS" type module, the FS-SDO-0824 (Part Number: FS-SDO-0824) is a non-conformal coated version, making it suitable for standard controlled industrial environments. It features advanced diagnostic capabilities, including watchdog (WDG) monitoring and suppression diode testing, to ensure the output circuit remains functional and can safely de-energize upon demand in accordance with SIL3-capable safety standards.
