Product Description


HIMA F3237 984323702 8-Channel Safety-Related Digital Input Module
HIMATRIX Series - Safety Input Module for SIL 3/AK 6 Industrial Safety Systems
1. Product Overview

The HIMA F3237 984323702 is an 8-channel safety-related digital input module designed for HIMATRIX safety systems, compliant with SIL 3 and AK 1-6 safety standards. It connects to NAMUR proximity switches (per DIN 19234) and resistor-wired sensors, featuring automatic on-line testing (switch, crosstalk, filter, short-circuit/line break detection) for fail-safe operation. With 681Ω shunt resistors, ≤50Ω line impedance, and 1000m max line length (0.5mm² wire), it ensures reliable signal acquisition in harsh industrial environments. The module integrates with HIMATRIX CPUs, providing redundant safety monitoring for critical processes in oil & gas, chemical, power, and automotive industries, minimizing safety risks and ensuring regulatory compliance.
