HIMA F3430 4-Fold Safety Relay Module | Integrated Shutdown | AK 1-6

HIMA F3430 Safety Relay Module Overview

The HIMA F3430 is a 4-fold relay module for safety applications. This module has integrated safety shutdown features. The HIMA F3430 provides safe isolation between input and output contacts. It uses 3 series relays for diversity and safety. A solid state output (open collector) drives an LED display in the cable plug. You can use this module in requirement classes AK 1 to 6 .

Technical Specifications

Switching Capacity Details

• AC max. – 500 VA, cos φ > 0.5

• DC up to 30 V – max. 120 W (non-inductive)

• DC up to 70 V – max. 50 W

• DC up to 110 V – max. 30 W

The HIMA F3430 has safe isolation according to EN 50178 (VDE 0160). Clearance in air and creepage distance fit overvoltage class III up to 300 V.

Fusing Recommendation

When using the HIMA F3430 in safety controls, fuse the output circuits at max. 2.5 A . This protects the module and connected devices.

Key Features

• Safety relay module – The HIMA F3430 meets AK 1 to 6 requirements.

• 3 series relays – Provides diversity for higher safety levels.

• Safe isolation – Input and output are fully isolated.

Installation Guide

1. Turn off all power to the system.

2. Mount the HIMA F3430 on a DIN rail (4 TE space).

3. Wire the input signals to the correct terminals.

4. Connect the load to the NO relay outputs.

5. Add a 2.5 A fuse to each output circuit for safety.

6. Apply power and test the switching function.

Always follow local safety codes. The HIMA F3430 requires proper grounding.

Frequently Asked Questions (FAQ)

1. What is the warranty period for the HIMA F3430?
We provide a 12-month warranty from the date of shipment. This covers manufacturing defects only. It does not cover misuse or improper installation.

2. Which shipping carriers do you use for this module?
We ship the HIMA F3430 via FedEx, UPS, or DHL. You can choose your preferred carrier at checkout. Tracking numbers are provided within 24 hours.

3. How do I know if my application needs AK 1 or AK 6?
Higher risk applications need higher AK levels. For example, a simple conveyor with low risk may use AK 1-2. A press or robot with high risk needs AK 5-6. Consult your safety engineer for the correct level.

4. Can I replace an old relay module with this HIMA F3430?
Yes, but check your wiring and voltage first. The HIMA F3430 works with AC up to 250V and DC up to 110V. Also verify that 4 TE space is available on your DIN rail.

5. Why does the module have 3 relays in series?
Three relays provide diversity and redundancy. If one relay welds shut, the other two still open. This is required for safety integrity levels. The HIMA F3430 uses this design to meet AK 1-6 standards.

Why Choose the HIMA F3430?

This safety relay module is simple and reliable. The HIMA F3430 uses 3 series relays for high safety. It works with AK 1 to 6 systems. Switching time is only 8 ms. Mechanical life exceeds 30 million operations. The module fits in 4 TE space on a DIN rail. Safe isolation protects your system from voltage spikes. Use it with Versamax and other PLC systems.
