Introduction to Honeywell SDI-1624 & FC-SDI-1624
FC-SDI-1624 Product Introduction
Honeywell SDI-1624 and FC-SDI-1624 are high-reliability 16-channel safety digital input modules, specifically engineered for industrial automation and safety instrumented systems (SIS). As core components for discrete signal acquisition, they are designed to accurately receive and process digital signals from on-site devices such as limit switches, proximity sensors, and emergency stop buttons, converting these signals into a format recognizable by Honeywell controllers for real-time monitoring and safety control. Both modules feature advanced photoelectric isolation technology between channels and channel groups, effectively suppressing electromagnetic interference and ensuring signal stability in harsh industrial environments. Equipped with built-in short-circuit and overvoltage protection functions, they can prevent damage to the modules and the entire system caused by external electrical faults. Their compact industrial-grade design supports standard DIN rail installation, facilitating easy integration into existing control cabinets.
