HIMA F3405 Relay Amplifier Module
Product Introduction
The HIMA F3405 is a high-integrity relay amplifier module designed for the Planar F series safety system. It provides galvanically isolated signal conditioning and relay driving for safety-critical applications, ensuring that field input devices can reliably trigger safety logic and initiate safe shutdown sequences. Its compact design combines robust electronics with diagnostics to simplify integration and maintenance in industrial environments.
Key Applications
-
Emergency Shutdown (ESD): Driving solenoid valves and shutdown relays in oil & gas, chemical, and power plants.
-
Safety Interlocks: Amplifying contact outputs from E-stop buttons and door switches to safety logic channels.
-
Fire & Gas Systems: Interface between gas detectors or flame sensors and safety controller inputs.
-
Critical Valve Control: Ensuring that fail-safe valves receive reliable trip signals in lost-power or fault conditions.
-
Redundant Safety Architectures: Serving as the interface module in dual-channel or three-channel safety loops.
Brand and Series
Brand: HIMA Paul Hildebrandt GmbH
Series: Planar F Safety System
HIMA’s Planar F series is a modular, scalable safety platform used worldwide in industries where SIL 3/SIL 4 functional safety is mandatory.
Product Advantages
-
High Integrity: Meets IEC 61508 SIL 3 and IEC 61511 requirements for safety-related control.
-
Galvanic Isolation: 4 kV isolation between input, output, and power rails prevents cross-channel faults.
-
Built-In Diagnostics: Monitors coil health and internal electronics, reporting faults to the safety controller.
-
Compact Footprint: Saves cabinet space without sacrificing performance or safety redundancy.
-
Hot-Swap Capability: Can be replaced during operation without shutting down the entire safety loop (with appropriate procedures).
