Product Overview
The FS-TSDI-1624 from Honeywell is a Safe Digital Input field termination assembly module. It interfaces the system interconnection cable (SICC-0001/Lx) with external field wiring through screw terminals. Designed for Class I, Division 2 hazardous locations, the module connects to redundant SDI-1624 modules to ensure reliable signal processing. Its PTC resistor protects each input channel from short-circuits, maintaining system integrity.
