Series: HIMatrix F3 / H41q / H51q Safety System

Type: 4-channel Fail-Safe Relay Output Module

Safety Level: SIL3, AK6, Cat.4/PL e (TÜV Certified)

Applications: SIS/ESD/BMS/F&G, drives solenoid valves, relays, contactors

Installation: Standard 4TE Rack Slot, supports hot swapping

II. Core Electrical Parameters

Channel: 4 independent relay outputs (single-pole double-throw SPDT)

Contact capacity: 250VAC / 30VDC, 5A (resistive)

Maximum switching voltage: 250VAC / 110VDC

Backplane power supply: 24VDC, ≤ 1.5W

Insulation isolation: 1500Vrms isolation between channels, system side and field side

Operating temperature: -20℃～+60℃

Protection / Size: IP20; 4TE (approximately 20mm wide)

III. Functions and Diagnostics

Safety mechanism: Fail-Safe, contacts safely open when power is lost

Drive capability: Directly drives 24V/48V solenoid valves, small contactors, alarm lights

Self-diagnosis: Full-channel coverage self-diagnosis, detects coil/contact faults, short circuits, open circuits

Indicator lights: LED for each channel status, power / fault indicator lights

Redundancy support: Compatible with QMR/TMR architecture, meets high safety redundancy requirements

IV. Typical Applications

ESD emergency stop system: Drive of critical valves / actuators

BMS boiler management: Fuel valve, igniter, purge valve control

F&G fire protection system: Alarm horn, sprinkler valve, fire door interlock

High-reliability interlock: Third-party system dry contact interface, safety barrier post-stage amplification

V. Comparison with the Same Series

F3414: 4-channel relay outputs, 250VAC/5A, standard SIL3

F3405: 4-channel relay outputs, 250VAC/5A, basic type

F3430: 4-channel safety relay, enhanced contacts, ≤ 110VDC/250VAC
