Product Overview
The Honeywell FS-TSDO-04UNI serves as a dedicated Field Termination Assembly (FTA) for digital output modules within the Safety Manager and FSC (Fail-Safe Controller) safety systems . This module connects the TDO-0424 and SDOL-0424 digital output modules to field actuators and solenoid valves . Moreover, the FS-TSDO-04UNI provides comprehensive line supervision and termination for four fail-safe output channels .
Technical Specifications
The FS-TSDO-04UNI operates with a 24 V DC supply and supports both floating and fixed power arrangements . This module employs the FS-BSDOL-04UNI range setting module for current threshold configuration, enabling precise monitoring per output . Furthermore, the unit’s robust terminal design accommodates field wiring up to 2.5 mm² (AWG 14) .

Key Design Features
The FS-TSDO-04UNI includes status indication LEDs that show the active condition of each output channel . This module provides terminal numbers and color-coded wiring diagrams printed directly on the housing for simplified installation and error-free termination . Additionally, the unit accommodates both two-wire and three-wire field device connections, delivering maximum flexibility for various actuator configurations . Users must fit the FS-BSDOL-04UNI Range Setting Module to adapt the monitoring thresholds to the specific load requirements of each output .
Application and Integration
The FS-TSDO-04UNI integrates seamlessly with Honeywell Safety Manager and FSC systems via SICC-0001/Lx system interconnection cables . System engineers commonly deploy this module in emergency shutdown (ESD) systems and safety instrumented functions (SIF) for controlling solenoid valves and actuators . Consequently, it plays a vital role in oil and gas, chemical processing, and power generation facilities requiring high-integrity digital output termination .
