Honeywell FC‑SDI‑1624 16‑Channel Safety Digital Input Module

Product Description

FC‑SDI‑1624 is a 16‑channel safety digital input module for Honeywell Safety Manager (FSC) fail‑safe control system. It acquires 24‑volt discrete switch‑state signals from field devices such as

emergency stop buttons, pressure switches, level switches and valve limit switches, and transmits validated data to the main safety controller via redundant safety bus. It meets IEC‑61508 SIL‑3

requirements and is widely deployed in oil‑refineries, natural‑gas processing plants, petrochemical complexes, offshore platforms and burner‑management systems for critical safety‑interlock

applications.
