Product Description

The FC-SDI-1624M is a high-integrity Safe Digital Input (SDI) module for the Honeywell Safety Manager system. It provides 16 discrete input channels for monitoring critical safety field devices such as emergency stop buttons, pressure switches, and light curtains. The "SDI" designation highlights its role as a primary data collector for Safety Instrumented Systems (SIS), ensuring fault detection and high reliability.

Engineered for harsh industrial environments, the FC-SDI-1624M operates across -40°C to +70°C and features a compact 100 mm cube design that supports high-density I/O configurations within standard control cabinets. With advanced internal diagnostics, it validates every input signal before processing, making it suitable for SIL 2 and SIL 3 safety loops in refineries, chemical plants, and power generation facilities.

Technical FAQ

What is the significance of the "M" suffix in FC-SDI-1624M?
The "M" indicates a specialized hardware revision with enhanced monitoring, optimized for redundant I/O carriers and high-availability Safety Manager configurations.

Can this module detect a broken wire in the field?
Yes. When paired with the correct Field Termination Assembly (FTA) and end-of-line resistors, the module can differentiate between a normal logic low signal and an open-circuit fault, providing reliable field wiring diagnostics.
