HIMA HIMatrix F3 DIO 8/8 01 is a safety remote I/O module developed by Germany-based HIMA. Part of the HIMatrix F3 series, it is engineered for Safety Instrumented Systems (SIS). The module features 8 safety digital input channels and 8 safety digital output channels. It communicates with HIMax and HIMatrix controllers via SafeEthernet to expand system I/O capacity. Complying with SIL 3, PL e and Cat.4 safety standards, it is ideal for safety control applications in high-risk industries such as petrochemical, power and metallurgy.
Product Features
1. Hardware Specifications
Input: 8 digital input (DI) channels, 24 VDC, max. 20 mA per channel. Compatible with passive contacts and equipped with built-in short-circuit protection for the power supply.
Output: 8 DO+ channels (common terminal L-, 0.5 A per channel), 2 DO- channels (common terminal S+ for enhanced load capacity) and 2 pulse output channels. Output voltage ≥ L+ - 2 V.
Power Supply: 24 VDC with tolerance of -15% ~ +20%; power consumption: 9 ~ 27 W.
Interfaces: 2 × RJ45 ports for SafeEthernet, pluggable screw terminals.
Dimensions & Weight: 205×86×100 mm, approx. 1.04 kg.
Protection & Environment: IP20 protection rating. Operating temperature: 0℃ ~ +60℃; Storage temperature: -40℃ ~ +85℃.
2. Safety & Diagnostics
Input Diagnostics: Detects wire short circuit and open circuit. The LED will trigger an alarm upon faults, and the program executes power-off trip logic.
Output Diagnostics: Detects external short circuits under bipolar mode. The faulty channel switches to safe state, and all outputs will be disabled in case of module failure.
Status Indication: LED indicators for power, system, communication and I/O status enable quick visual diagnosis.
3. Software Configuration
Configuration Tools: SILworX (V7 and above), ELOP II Factory.
Parameters: Input filter, output delay and communication parameters are configurable.
Protocol: Adopts SafeEthernet for seamless communication with HIMax and HIMatrix controllers.

FAQ
Q: Does F3 DIO 8/8 01 have explosion-proof certification?A: It comes with standard ATEX Zone 2 certification and TÜV certificates available. Suitable for non-hazardous areas and Zone 2 hazardous locations.
Q: Is it compatible with non-HIMA controllers?A: It only works with HIMax and HIMatrix controllers via SafeEthernet, and is incompatible with third-party PLCs.
Q: What is the delivery lead time?A: In-stock items: 3–5 days; Stock transfer orders: 4–6 weeks.
Q: How to replace a faulty module?A: Power off the system and replace it with an identical module, then download the configuration again. No reprogramming is required. Hot swapping is supported under redundant system configuration.
Q: Will the output recover automatically after a short circuit?A: The output will be cut off and the FAULT LED will light up upon short circuit. It restores automatically after the fault is removed. Latch mode requiring manual reset is also configurable.
Q: How to verify normal operation of safety functions?A: Perform Proof Test via SILworX by simulating input faults and output actions. Generate and archive the test report.
Q: How to upgrade the firmware?A: Connect to the module via SILworX for online firmware upgrade. The system provides automatic protection during the process to prevent damage caused by power failure.
