Honeywell FC-TSDO-04UNI Digital Output Module

Four Configurable Outputs for Flexible Field Control

The Honeywell FC-TSDO-04UNI offers four universal digital output channels for driving a variety of field devices. This module supports both fail-safe and non-fail-safe configurations, adapting to diverse application requirements . It integrates seamlessly with Honeywell Safety Manager, FSC, and Experion PKS platforms . The FC-TSDO-04UNI outputs can drive loads directly without external interposing relays. Its robust design includes comprehensive diagnostics for each channel, ensuring reliable operation in demanding environments.

Flexible Output Types and Connectivity

Each channel provides configuration options for 24 V DC sourcing or sinking outputs . The module also supports relay contact outputs for isolated switching of AC or DC loads . This flexibility makes the FC-TSDO-04UNI suitable for controlling solenoids, alarm horns, motor starters, and indicator lights. The module connects to the system via the SICC-0001/Lx interconnection cable. Screw terminals accept field wiring up to 2.5 mm² (AWG 14) with a 7 mm strip length.
