Detailed Product Overview
The HIMA F3 AIO 8/4 01 functions as a distributed analog I/O extension for HIMA safety controllers. It acquires process signals on eight analog input channels and provides four analog output channels, transferring all data safely over the proprietary safeethernet protocol. The module itself contains no user program; all logic, diagnostics evaluation, and safety reactions are executed in the connected HIMax or HIMatrix controller.
The analog inputs support unipolar voltage measurement referenced to L− and, with external shunt adapters, current measurement (0/4–20 mA). Transmitter supplies are available on the input side. The four analog outputs are classified as non-safety-related; however, they can be forced to a safe state (all outputs switched off) by the controller through dual safety switches. To achieve full SIL 3 for output functions, the application program must read the actual output values back through safety-related analog inputs and implement the required reaction logic.
Two RJ-45 ports with an integrated switch allow line or ring topologies on the safeethernet network. Power is supplied at 24 VDC from a source with safe isolation according to IEC 61131-2. The compact metal housing is designed for industrial environments and is approved for installation in Ex Zone 2.
The module is available in variants supporting different programming tools (SILworX or ELOP II Factory) and extended temperature ranges. The standard F3 AIO 8/4 01 version is specified for 0 to +60 °C operation.
Dimensions, Mounting & Connection Notes
The F3 AIO 8/4 01 is supplied in a compact metal housing intended for remote mounting. Field wiring for analog inputs and outputs is connected via front or side terminals. Two RJ-45 sockets provide the safeethernet link. Power is supplied through dedicated terminals. The module is suitable for installation in Ex Zone 2 when the appropriate installation rules are observed. Exact outline dimensions and terminal assignments are given in the official HIMA hardware manual HI 800 161.

Engineering Selection Highlights
- Eight safety-related analog inputs with transmitter supplies enable direct connection of 0–10 V or 0/4–20 mA field signals.
- Four analog outputs can be collectively de-energized by the controller, supporting safety-related shutdown when combined with read-back via safety inputs.
- safeethernet communication with dual RJ-45 ports and integrated switch simplifies network topology in distributed safety architectures.
- TÜV certification up to SIL 3 / PL e and railway SIL 4 allows use in both process and transportation safety applications.
- Compact metal housing and Ex Zone 2 suitability support installation close to the process in hazardous areas.
- No local user program reduces engineering complexity; all application logic remains centralized in the HIMax/HIMatrix controller.
- 24 VDC power supply with wide tolerance matches standard industrial control power systems.
System Compatibility & Integration Requirements
| Item / Dependency | Verified Compatibility or Requirement | Practical Note |
|---|---|---|
| Host controllers | HIMax and HIMatrix systems | Connected exclusively via safeethernet |
| Programming tools | SILworX or ELOP II Factory (variant-dependent) | Module does not store or execute user logic |
| Network | safeethernet (10/100BaseT) | Dual RJ-45 ports with integrated switch |
| Power supply | 24 VDC with safe isolation (IEC 61131-2) | −15 % to +20 % tolerance |
| Current measurement | External shunt adapters (e.g., Z 7302, Z 7309) | Required for 0/4–20 mA signals |
| Safety integrity | SIL 3 / PL e (outputs require read-back logic) | Application program must implement diagnostics |
FAQ
What is the HIMA F3 AIO 8/4 01?
It is a safety-related remote I/O module with 8 analog inputs and 4 analog outputs for use with HIMax and HIMatrix controllers.
Are the analog outputs safety-related?
No. The four outputs are non-safety-related, but the controller can switch all of them off simultaneously via dual safety switches. SIL 3 for the outputs requires read-back through safety inputs and application logic.
How does the module communicate?
Via safeethernet using two RJ-45 ports with an integrated switch operating at 10/100 Mbit/s.
What safety certifications does it hold?
TÜV-certified for SIL 3 (IEC 61508, IEC 61511, IEC 62061), Category 4 and PL e (EN ISO 13849-1), and SIL 4 according to EN 50126/50128/50129.
What is the operating temperature range?
0 to +60 °C for the standard F3 AIO 8/4 01 variant.
Can the module run a user program?
No. It functions solely as a remote I/O extension; all application logic resides in the connected controller.
Is it suitable for hazardous areas?
Yes, it is approved for installation in Ex Zone 2.
Verification & Troubleshooting Notes
Front-panel LEDs indicate module status, communication activity, and fault conditions. A FAULT LED signals internal module errors that force all outputs to the off state. Diagnostic information, including detailed error codes for individual channels, is transmitted to the controller via safeethernet and must be evaluated in the application program.
Verify that the 24 VDC supply remains within the specified tolerance and that the safeethernet network is correctly terminated and configured. Confirm that any required shunt adapters for current inputs are installed and that the application program implements the necessary read-back and reaction logic for the analog outputs when SIL 3 is required.
