Overview
The Honeywell FS-TSRO-0824, also cataloged as the TSRO-0824 Safe Dry Digital Output Field Termination Assembly, provides eight relay-based output channels for Safety Manager safety instrumented systems. It interfaces the SICC-0001/Lx system interconnection cable with external field wiring. Each channel uses relay contacts to switch field circuits, with fused normally open contacts and individual LED status indicators.

Relay Output Architecture and Safety Interface
The FS-TSRO-0824 uses relay-based switching to provide eight separate field output circuits. Each channel incorporates three relays, a fused normally open field contact, and an LED status indicator. The floating, non-commoned contacts allow field circuits to be wired independently, subject to the applicable system wiring and electrical ratings.
The assembly connects to the SICC-0001/Lx system interconnection cable. Before integrating the module into a safety-related output circuit, verify the applicable Safety Manager hardware configuration, approved wiring diagrams, fuse ratings, and load characteristics. The stated SIL 3 classification must be confirmed against the manufacturer’s certification and the complete safety loop configuration.
Frequently Asked Questions (FAQ)
Q: How many output channels does the FS-TSRO-0824 provide?
A: The assembly provides eight relay-based output channels, each with a fused normally open field contact and an individual LED status indicator.
Q: What are the maximum specified output ratings?
A: The supplied specifications state a maximum output current of 5 A per fused output, a maximum switching voltage of 250 VAC or 250 VDC, and maximum switched loads of 1250 VA AC or 150 W DC. Confirm the manufacturer’s contact ratings and load-specific restrictions before connecting field equipment.
Q: Are the output contacts electrically commoned between channels?
A: The specified contacts are floating and non-commoned. Each field circuit can therefore be wired independently within the module’s approved electrical limits and system wiring requirements.
Field Installation Guidelines
- Verify the complete model number and hardware compatibility with the intended Honeywell Safety Manager configuration before installation.
- Confirm that the SICC-0001/Lx interconnection cable matches the applicable system wiring documentation.
- Isolate field power before connecting or disconnecting output wiring.
- Observe the specified voltage, current, fuse, and switching-load limits for each output circuit.
- Keep field wiring organized and separate from noise-sensitive signal wiring where required by the installation design.
- Apply grounding, shielding, and cable routing practices specified in the manufacturer’s installation documentation.
- Verify relay operation, LED status indication, and field load response during commissioning.
- Do not assume hot-swap capability or a particular de-energized output state without confirmation in the official hardware documentation.
