High-Density Safety-Certified Analog Input Module for Critical Industrial Operations


The Honeywell FS-SAI-1620m is a 16-channel analog input module engineered for safety-critical industrial automation systems. Certified to SIL3 and compliant with FM 3611 (Class I/II, Division 2) standards, it ensures reliable performance in hazardous environments while supporting 0–4.1V analog signals. The module operates on dual power supplies (5V DC and 24V DC), delivering redundancy for mission-critical applications. Its compact 4TE, 3HE form factor allows space-efficient DIN rail or panel mounting, making it suitable for oil & gas, petrochemical, and power generation facilities. With CE, TÜV, UL, and CSA approvals, it meets global safety requirements, providing fail-safe operation in non-hazardous and Division 2 locations.

Precision Signal Processing with Robust Interference Resistance


Featuring a 12-bit A/D converter and <0.25% module accuracy, the FS-SAI-1620m ensures precise data acquisition for temperature, pressure, and flow monitoring. It supports a wide input range (±36V DC) and offers >60dB cross-channel isolation, minimizing signal interference in noisy industrial settings. EMI/RFI shielding and surge protection safeguard against electrical noise, while a 1MΩ input impedance and 100nF load capacitance tolerance enable compatibility with diverse sensors. The module’s hot-swap capability allows maintenance without system shutdown, enhancing operational continuity. Ideal for high-speed process control, it integrates seamlessly with Honeywell’s Safety Manager and Experion PKS platforms, enabling real-time analytics and predictive maintenance.

Modular Design for Scalable Automation Solutions


Designed for flexibility, the FS-SAI-1620m supports modular expansion in Honeywell’s Safety Manager ecosystem. Its 16-channel configuration reduces cabling complexity, while M12 connectors ensure secure, vibration-resistant signal transmission. Weighing 0.25 kg, the module is lightweight yet durable, with an operating temperature range of -20°C to +60°C. Backed by a 1-year warranty and Honeywell’s global technical support, it delivers long-term reliability for applications such as burner management, emergency shutdown systems, and smart infrastructure. Compatible with third-party systems via Modbus RTU and Profibus DP, it bridges legacy and modern automation frameworks, offering cost-effective solutions for industrial digital transformation.
