Compatible Replacement & Equivalent Models
When the FS-RO-1024 is discontinued, on long lead time, or requires a cost-effective alternative, the following models may serve as functional equivalents depending on your system configuration. Always verify compatibility with your system integrator before substitution.
| Model | Brand | Channels | Output Type | Compatibility Notes |
|---|---|---|---|---|
| FS-RO-1024 | Honeywell | 24 | Relay (SPDT) | OEM original — direct fit |
| FS-DO-1024 | Honeywell | 24 | Digital Output (solid state) | Same form factor; solid-state alternative |
| FS-RO-0816 | Honeywell | 16 | Relay (SPDT) | Reduced channel count variant |
| HC900 Relay Output Module | Honeywell | 8/16 | Relay | Different platform; requires engineering review |
| Triconex 3625 | Schneider Electric | 16 | Relay Output | TMR architecture; cross-platform migration only |
| HIMA F3 DO 8/8 01 | HIMA | 8 | Digital Output | SIL 3 rated; cross-platform migration only |
Note: Cross-brand replacements require full system re-validation. Contact Konmask for engineering support.
Why Choose the Original FS-RO-1024
- Certified SIL 2 performance — validated for use in safety-instrumented systems per IEC 61508 / IEC 61511.
- Seamless backplane integration — plug-and-play replacement within existing Honeywell FS racks with no firmware changes.
- Proven field reliability — widely deployed in oil & gas, petrochemical, and power generation facilities globally.
- OEM support & lifecycle — full Honeywell technical support, spare parts availability, and documented change history.
- Dry contact isolation — galvanically isolated relay outputs reduce noise and protect field devices.
Typical Applications
- Fire & gas detection and suppression control panels
- Emergency shutdown (ESD) systems in oil & gas facilities
- Burner management systems (BMS)
- Compressor and turbine safety interlock systems
- Offshore platform safety logic controllers
- Chemical plant process safety systems
System Compatibility
The FS-RO-1024 is designed exclusively for the Honeywell FS Safety System platform. It is compatible with:
- Honeywell FS Controller (FSC) series racks
- Honeywell Safety Manager (SM) platform (verify revision compatibility)
- FS series power supply and communication modules
- Honeywell Safety Builder / FSC Tools configuration software
Not compatible with Honeywell Experion PKS standard I/O racks or HC900 controller series without hardware adaptation.
Selection Guide
Use the following criteria to confirm the FS-RO-1024 is the correct module for your application:
- Channel count: Requires 24 relay output channels per module slot? → FS-RO-1024 ✓
- Output type: Dry contact relay (SPDT) required for field device isolation? → FS-RO-1024 ✓
- Safety integrity: SIL 2 loop required per IEC 61511? → FS-RO-1024 ✓
- Platform: Existing Honeywell FS / FSC rack infrastructure? → FS-RO-1024 ✓
- Need fewer channels or solid-state output? → Consider FS-RO-0816 or FS-DO-1024
- Cross-platform migration? → Contact Konmask for a full migration feasibility study

Replacement & Compatibility FAQ
Q: Can I replace FS-RO-1024 with FS-DO-1024 directly?
A: Both share the same form factor and backplane interface. However, FS-DO-1024 uses solid-state outputs instead of relay contacts. Verify field wiring and load compatibility before substitution.
Q: Is the FS-RO-1024 still in production?
A: Honeywell periodically updates its FS product lifecycle status. Contact Konmask for current availability and recommended long-term alternatives.
Q: Can I use a third-party relay output module in my FS system?
A: Third-party modules are generally not supported on the Honeywell FS backplane. Cross-platform migration requires full system re-engineering and re-validation.
Q: What is the minimum order quantity?
A: No minimum order quantity. Single units available. Volume pricing available for orders of 5+ units.
Q: Do you provide a warranty?
A: Yes. All units carry a minimum 90-day functional warranty. Extended warranty options available on request.
