The Honeywell FS-TSDO-04UNI, also cataloged as the FS-TSDO-04UNI Safe Digital Output Module, operates as a dedicated hardware component for controlled 24 VDC signal switching within Honeywell Safety Manager systems. It provides four output channels with defined current limitation and compliance to safety approvals.
Hardware Specifications
Model: FS-TSDO-04UNI
Brand: Honeywell
Origin: USA
Weight: Approx. 2–3 Kg
Dimensions: Modular rack-mounted form factor
Operating Temp: 0 to 60 deg C typical
Power Supply: 24 VDC nominal input
Output Channels: 4 digital outputs
Output Voltage: 24 VDC solid-state source
Continuous Current per Channel: Defined by connected output module (safe current-limited)

4-20 mA HART Loop Protocol
The FS-TSDO-04UNI integrates into Honeywell Safety Manager systems with 4-20 mA HART loop protocol diagnostics. Channel-to-channel isolation ensures fault containment, while galvanic isolation protects control logic from field interference. This design supports compliance with SIL-rated safety requirements and ensures safe output distribution.
Frequently Asked Questions
Q: Can the FS-TSDO-04UNI be hot-swapped during operation?
A: Hot-swap is supported when output circuits are isolated; loads must be de-energized before removal or insertion.
Q: How does overload detection function?
A: Overload protection is defined by the connected output module; the FS-TSDO-04UNI provides safe current-limited termination.
Q: Is firmware upgrade required for integration?
A: No firmware upgrade is required; the module functions as a fixed hardware output unit.
