Function

SIL2 safety relay module.It adopts sealed relay and safe isolation design,accepts control signal from safety controller and switches field load circuit.The LED lamp shows relay coil energized status.Low power consumption allows direct drive from safety I/O modules without extra amplifier.

Installation

Clip onto standard DIN rail in control cabinet,wire input coil and field contact circuit.

Interface

‑Input coil wiring terminals

‑Potential-free changeover contact terminals

‑LED indicator for relay status

Circuit feature

Safe electrical separation between input and output,sealed relay construction,compact design,meets SIL2 functional safety requirements for hazardous industrial environment.

Feature

HIMatrix series SIL2 safety relay H4116. Common faults:contact aging,coil burnout,terminal corrosion.Check wiring before commissioning.

Diagnostic

Relay coil fault or contact damage causes abnormal status shown by LED indicator;controller executes safety interlock logic.

Built‑in function

H4116 is used for switching safety-related load circuits in SIS safety instrumented system emergency shutdown protection,widely used for process plant safety spare replacement.
