HIMA X-AI 32 01 Product Specification
1. Product Overview
The HIMA X-AI 32 01 is a safety-related analog input module tailored for HIMA’s HIQuad X and HIMax safety instrumented systems (SIS). As a critical data acquisition component in industrial safety loops, it converts continuous analog signals from field sensors (e.g., pressure, temperature, flow transmitters) into digital signals for the central safety controller. Widely deployed in high-risk industries such as oil & gas, petrochemical, chemical processing, and nuclear power, this module ensures accurate and reliable collection of critical process parameters, laying the foundation for the execution of safety functions like emergency shutdown and process interlock.
Compliant with international safety standards including IEC 61508 (SIL 3) and IEC 61511, the X-AI 32 01 features a dual-channel redundant design, high-precision signal conditioning, and comprehensive self-diagnostic functions. It maintains exceptional performance in harsh industrial environments with electromagnetic interference, temperature fluctuations, and vibration, meeting the stringent safety and reliability requirements of process industries.

3. Key Features
3.1 Clear Visualization & Intuitive Operation
With ±0.1% FS accuracy for 4–20 mA signals and ±0.2% FS for voltage signals, the X-AI 32 01 ensures precise collection of critical process parameters (e.g., pipeline pressure, reactor temperature). Advanced signal conditioning technology minimizes noise interference, while temperature compensation (over -20°C–60°C) reduces measurement drift, ensuring reliable data even in harsh environmental conditions.
3.2 SIL 3 Safety & Fault Tolerance
Certified for SIL 3 operation per IEC 61508, the module adopts a dual-channel redundant design with hardware fault tolerance (HFT = 1), ensuring data acquisition continuity even if a single channel fails. Comprehensive self-diagnostics (≥99% diagnostic coverage) detect faults such as signal loss, short circuits, and module overheating, triggering immediate alerts to the SIS controller.
3.3 Flexible Channel Configuration
Each of the 32 input channels can be independently configured via HIMA’s HIMatrix Engineering Studio for 4–20 mA, 0–10 V, or 1–5 V signals. This flexibility allows the module to connect to diverse field sensors, eliminating the need for multiple dedicated modules and simplifying system design in mixed-signal safety loops.
3.4 Seamless SIS Integration
Optimized for HIMA’s flagship SIS platforms, the module supports plug-and-play installation via the system backplane and automatic parameter synchronization. It integrates seamlessly with HIMA’s safety control software for centralized monitoring, calibration, and fault diagnosis, reducing deployment time and operational complexity in large-scale safety systems.
