Product Overview
The Honeywell FC‑TSPKUNI‑1624 is a dedicated field termination assembly for Honeywell Safety Manager SIS RUSIO remote I/O system. It converts 37‑pin Sub‑D controller interface into field‑wirable knife‑style terminals for 16 safety I/O channels, with individual channel fuse protection for 24 VDC field circuits. This FTA acts as physical wiring bridge between Safety Manager RUSIO modules and field sensors / actuators. Original manufacturing is discontinued; replacement part number is FC‑TSPKUNI‑1624R, widely used as spare‑part for existing safety instrumented system maintenance and retrofit projectsHoneywell.

Product Specifications
- Electrical isolation: Galvanic separation between field wiring and controller back‑plane
- Fuse function: Individual channel over‑current protection prevents single‑channel fault spreading to other safety loops
- Mechanical: Snap‑in DIN‑rail installation, compact cabinet‑friendly form‑factor
- Compatibility: Matches Honeywell Safety Manager RUSIO remote I/O hardware
- Lifecycle: Original production withdrawn March‑2022, available as surplus / refurbished spare parts onlyHoneywell
- Wiring: Designed for field sensors, solenoid valves and safety‑related 24VDC field devices
Function
- Provide physical termination interface between Safety Manager RUSIO I/O modules and field safety instruments
- Distribute 24 VDC field power to each I/O channel with individual fuse protection
- Isolate field wiring faults to single channel, avoid fault propagation across safety loops
