Safety-Certified Digital Input Module for Critical Industrial Systems


The Honeywell FS-SDI-1624 is a 16-channel digital input module engineered for safety-critical industrial automation applications. Certified to SIL3 and compliant with CE, UL, CSA, and TÜV standards, it ensures reliable performance in hazardous environments. Supporting 24V DC input, the module offers a wide voltage range (20–30V DC) and high input impedance (100 kΩ), minimizing signal interference. Its compact design (100 × 65 × 25 mm) and lightweight construction (0.4 kg) facilitate easy installation in space-constrained control panels. With hot-swap capabilities and dual power redundancy, it enables seamless maintenance without system shutdown. Ideal for oil & gas, petrochemical, and power generation sectors, it integrates with Honeywell’s Safety Manager and Experion PKS systems, delivering real-time monitoring for emergency shutdowns and process safety.

High-Performance Signal Handling with Advanced Diagnostics


Featuring a rapid response time (<1 ms) and ±36V transient protection, the FS-SDI-1624 ensures precise data acquisition for digital signals from sensors, switches, and encoders. Its built-in diagnostic tools detect wiring faults, short circuits, and overvoltage conditions, streamlining troubleshooting. The module supports isolated inputs with cross-channel isolation exceeding 60 dB, enhancing noise immunity in electrically noisy environments. EMI/RFI shielding and surge protection safeguard against electromagnetic interference, while a rugged aluminum alloy enclosure provides IP65-rated resistance to dust and moisture. Compatible with Honeywell’s Fault Tolerant Architecture (FTA), it supports scalable configurations for both small and large-scale automation systems.

Versatile Integration for Diverse Automation Applications


Designed for flexibility, the FS-SDI-1624 interfaces with Modbus RTU, Profibus DP, and Honeywell’s IO-Bus protocols, enabling interoperability with legacy and modern control systems. Its modular design allows easy expansion, making it suitable for applications such as burner management, conveyor control, and smart infrastructure. The module operates across a wide temperature range (-40°C to +85°C) and includes LED indicators for real-time status monitoring. Backed by a 1-year warranty and Honeywell’s global technical support, it delivers long-term reliability for mission-critical operations. Whether used in manufacturing, water treatment, or energy sectors, the FS-SDI-1624 combines safety certification, high-speed performance, and ease of integration to optimize industrial automation efficiency.
