HIMA X-AI3201 32-Channel SIL3 HART Analog Input Module

Product Description

X-AI3201 is HIMA X-series high-density safety analog input module for H51q/H41m safety controllers.

It collects 4–20mA HART signals from pressure, temperature and flow transmitters, each channel with independent isolation and sensor fault diagnosis. Connects to main CPU 

via dedicated X-Bus safety bus, conformal coated PCB, single-slot rack plug-in design, core spare for ESD, FGS and SIS safety instrument systems.

Key Features

32-channel high-density layout reduces rack occupation for large-scale SIS measurement points.

Built-in HART demodulator reads transmitter diagnostic data without extra gateway equipment.

Independent channel isolation eliminates ground loop interference and cross-channel signal crosstalk.

Full self-diagnosis detects open circuit, short circuit and signal overrange for safety interlock alarm.

TÜV certified SIL3 safety integrity, applicable to high-risk petrochemical and power plant ESD systems.

Dedicated X-Bus synchronous bus ensures real-time safe data transmission between I/O and safety CPU.

Front panel LED indicators display channel running and fault status for fast on-site troubleshooting.

Anti-vibration coated PCB and rugged metal housing, stable 24/7 continuous safety system operation.
