Description
The FS-SDI-1624 module is a key component of Honeywell Safety Instrumented Systems (SIS),
designed to provide reliable signal detection and processing capabilities for critical industrial
applications requiring safety levels such as IEC 61508 SIL3. This module monitors the switching
signals from various safety-related field devices, such as emergency stop switches, safety relays,
and limit switches, and transmits these binary signals securely and accurately to the safety
controller so that the system can respond according to preset safety logic.

Features
Safety Certification: TÜV IEC 61508 SIL3 certified, ensuring compliance with the
highest level of functional safety requirements.

High Reliability: Designed for industrial safety applications, providing stable and reliable
signal input, eliminating the risk of single points of failure.

Fast Response: Approximately 10 milliseconds input delay ensures the safety system
can respond promptly to emergencies.

Wide Voltage Range: Supports a wide input voltage range of 24 VDC to accommodate
various field device requirements.

Diagnostic Functions: Provides diagnostic features for easy troubleshooting and system
maintenance, ensuring system integrity.

Environmental Adaptability: Rugged and designed for harsh industrial operating environments,
but this FS version does not have a conformal coating and is typically used in milder environments.
