Description

The F3422 is an 8-channel relay output module from the HIMA HIQuad X safety system family, manufactured by HIMA Paul Hildebrandt GmbH in Germany. It provides eight independent SPDT (Form C) relay outputs for switching control signals in safety-critical industrial automation applications.

Each channel is equipped with a silver-nickel (AgNi 0.15) contact relay capable of switching up to 60 V DC or AC at 4 A continuous current, with inrush current capability of 12 A peak for 4 seconds. AC load capacity is 240 VA for non-inductive loads; DC load capacity is 120 W for non-inductive loads. The eight relays are electrically isolated from each other and from the system electronics.

The module operates from a 24 V DC supply with ±15% tolerance, drawing approximately 1.2 A during switching operations. Tool-less terminal blocks enable rapid channel replacement without specialized tools, reducing maintenance time during plant outages.

Information

Overview Manuals Application Notes Product Applications Power & Signal Connection

Features:

  • Eight independent relay output channels
  • Maximum switching voltage of 60 VAC / 60 VDC
  • DC switching capacity up to 120 W
  • Electrical life exceeding 100,000 operations
The HIMA F3422 is an 8-channel relay output module designed for use in HIMA safety-related control systems. The module provides electrically isolated relay outputs for switching field devices in applications requiring dependable signal isolation and reliable relay operation. It is commonly installed in Safety Instrumented Systems (SIS), Emergency Shutdown (ESD) systems, and other high-availability industrial automation platforms.

The module incorporates eight independent relay channels, each capable of switching loads up to 60 VAC or 60 VDC with a maximum switching current of 4 A per channel. Each relay contact uses AgNi 0.15 hard gold-plated contact material, providing low contact resistance and stable switching performance over an extended service life.

The F3422 HIMA 8-Channel Relay Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

For applications with inductive or high-startup loads, each relay channel supports an inrush current of up to 12 A for 4 seconds. The relay contacts are rated for 240 VA AC or 120 W DC on non-inductive loads, making the module suitable for switching solenoid valves, alarm circuits, contactors, interposing relays, annunciators, and other industrial field devices.
 
The relay contacts are fully isolated from one another, minimizing electrical interference and preventing fault propagation between circuits. The module also provides an open-collector status output that can be connected to external indicators or monitoring circuits for relay status feedback. This simplifies diagnostics and system maintenance while allowing remote monitoring of relay operation.

Cable Requirements: Use shielded, twisted-pair cables with a minimum cross-section of 0.75 mm² for field wiring, and ensure proper cabinet grounding and equipotential bonding per HIMA guidelines.
Field Wiring: Connect field devices to the F 3422 through the system’s pre-assembled cable plugs and terminal blocks.
Voltage Limitations: Only voltages of the same potential are permitted to be connected to the I/O channels of the F 3422 module.

Technical notes

Operating temperature range is -20°C to +60°C, with power derating required above +45°C. Storage temperature is -40°C to +85°C. The module is rated IP20 and must be installed within a control cabinet. The F3422 carries SIL 3 certification per IEC 61508 and IEC 62061, qualifying it for use in safety instrumented systems. It also carries CE marking, UL 60947-5-1 listing, and ATEX Zone 2 approval for oil and gas applications

FAQs

  • What is the F3422 ?

    +
    The HIMA F3422 is an 8-channel safety-related digital output module used in industrial automation and Emergency Shutdown Systems (ESD).
  • What types of loads can the F3422 drive?

    +
    The module is designed for non-inductive loads up to 240 VA (AC) and 120 W (DC). While designed as a relay module, it safely isolates field devices and can interface directly with emergency shutdown valves and alarm signaling systems.
  • Does the F3422 support system redundancy?

    +
    Yes. Depending on your installation’s safety and availability requirements, the HIMA system allows for redundant I/O module configurations. If one safety module fails, it is automatically switched off while the redundant module seamlessly continues operation.
  • Which legacy and modern systems is the F3422 compatible with?

    +
    The module is primarily associated with legacy HIMA system families like the H41q and H51q series. Modern replacements and upgrades are generally evaluated based on the specific HIMA automation hardware family (e.g., HIMax, HIMatrix, or HIQuad X) being integrated into your plant.
