Honeywell FC-SDI-1624 Safety Manager Digital Input Module
1. Product Overview
FC-SDI-1624 is a safe digital input (SDI) module for the Honeywell Safety Manager (SMS) system (also used in Experion PKS C300/C500). Designed for safety instrumented systems (SIS), it has 16 channels at 24 V DC to acquire discrete on/off signals from emergency stop buttons, limit switches and pressure switches, converting them quickly and reliably into digital signals for the controller.
Built for safety-critical applications, it provides high integrity and fast response, working with Honeywell's QMR redundancy architecture to maintain process availability.
