The Honeywell FS-SDI-1624 is a high-integrity 16-channel digital input module designed for Honeywell Safety Manager and Fail-Safe Control (FSC) systems. It continuously monitors critical field devices—such as emergency stop buttons, pressure switches, and flame detectors—and converts these signals into safety-processed data for the central controller. We supply this unit as 100% brand new and original, delivering the certified reliability required for Safety Instrumented Functions (SIF) up to SIL3 capability.

Self-Diagnostic Capabilities
The FS-SDI-1624 performs continuous internal diagnostics to detect hardware faults and cross-talk, ensuring the module transitions to a safe state in the event of internal failure.
Line Monitoring Technology
Advanced input monitoring detects field wiring faults such as short circuits and open loops, allowing the system to distinguish between real process trips and wiring issues.
Galvanic Isolation
Robust isolation barriers protect the system bus from field-side surges and electrical transients, safeguarding the controller and maintaining signal integrity.
High-Density Safety Design
Its ultra-slim 2.2 cm width enables 16 safety channels in a compact footprint, reducing overall cabinet space and I/O rack requirements.
Rapid Signal Response
Low-latency input processing ensures fast detection of safety events, supporting rapid shutdown sequences in high-risk industrial environments.
Does this module support redundant configurations?
Yes. The FS-SDI-1624 can be integrated into redundant architectures such as 1oo2 or 2oo3 within Honeywell Safety Manager systems to enhance safety and availability.
How can I verify authenticity?
Each unit is delivered as 100% brand new in original Honeywell packaging with holographic seals and a verifiable manufacturing date code.
What field voltage does it require?
It operates on a nominal 24 VDC input signal. Field power must remain within specified tolerance limits for stable operation.
Is the module hot-swappable?
In redundant configurations, the FS-SDI-1624 can be replaced without full shutdown when proper Honeywell maintenance and safety bypass procedures are followed.
