16-CH 24V DC Digital Output | FC-TDO-1624 | Honeywell

Product Overview

The FC-TDO-1624 (Model: FC-TDO-1624) is a high-performance 16-channel digital output module engineered for Honeywell Safety Manager®, Fail-Safe Controller (FSC), and Experion® SIS platforms. This module acts as the critical execution layer in safety-instrumented systems, converting low-level controller logic into robust 24V DC discrete signals to drive field actuators.

Designed for millisecond-precision switching, the FC-TDO-1624 (Part Number: FC-TDO-1624) is essential for managing solenoids, interposing relays, and motor contactors in high-consequence environments. Its architecture emphasizes galvanic isolation and fault tolerance, ensuring that electrical noise or field-side short circuits do not propagate back to the central logic solver. This module is a cornerstone for Emergency Shutdown (ESD) and Fire & Gas (F&G) logic execution in refineries, power plants, and offshore platforms.
