Description
Core Product Summary
The HIMA F3430 is a 4-fold safety-related relay module engineered for HIMA HIQuad safety controller systems (including H41q and H51q series). Designed for high-integrity safety instrumented systems, this module provides four independent relay output channels equipped with integrated safety shutdown and safe isolation.
Engineering integration is anchored by a redundant series-relay architecture using diverse switching paths to ensure dependable de-energization of critical field loads. The module handles switching voltages up to 250 V AC or 110 V DC while providing solid-state open-collector outputs for front-connector LED status indication. It occupies 4 TE of rack width and requires standard external fusing to protect safety output circuits.

Detailed Product Overview
The HIMA F3430 acts as a reliable output interface module for safety instrumented systems, bridging controller logic to high-voltage or heavy-duty field actuators such as shutdown valves, safety contactors, and alarm sirens. Its internal architecture incorporates series-connected relays arranged in diversity to execute reliable, fault-tolerant safety shutdowns.
Safe isolation between internal logic circuitry and field contacts adheres to EN 50178 standards, protecting control networks from high-voltage transients. The module’s gold-flashed silver alloy contacts maintain low contact resistance over extended operating lifespans, while open-collector solid-state outputs drive front-panel connector LEDs to provide clear visual channel-state monitoring.
