Honeywell FS-TSDO-04UNI Safe Digital Output FTA Module

The Honeywell FS-TSDO-04UNI is a Safe Digital Output Field Termination Assembly (FTA) used in industrial safety and process automation systems. It provides reliable, fail-safe digital outputs for driving field devices as part of a Safety Instrumented System (SIS).

Key Features

• 4 independent safe digital output channels
• Universal output capability suitable for a wide range of field devices
• Fail-safe operation — outputs revert to a safe state during fault conditions
• High-integrity wiring interface between controller and field equipment
• DIN-rail mounting for easy installation
• Robust industrial-grade design for harsh environments
• Typically used in Safety Manager, ESD, Fire & Gas, and critical interlock systems
