HIMA’s technical documentation identifies the F3 DIO 20/8 02 as a remote I/O device with 20 digital inputs and 8 digital outputs, two integrated Ethernet switch ports, and configurable line monitoring. The module communicates its input values to a connected HIMax or HIMatrix controller through SafeEthernet and does not execute the user application itself.
The IECEx certificate gives 20.4–28.8 V rated supply voltage and 0°C to +60°C ambient temperature for the listed F3 DIO 20/8 02 configuration. Other hardware variants in the same HIMatrix family have different environmental ranges, so the exact nameplate and applicable certificate should be checked for a replacement installation.
Product Introduction
The HIMA /802 982200442 is a HIMatrix safety-related remote I/O device designed to extend the digital I/O capacity of HIMax and HIMatrix safety systems. It combines 20 digital inputs with 8 digital outputs and communicates with the safety controller through HIMA SafeEthernet over its integrated two-port 100Base-TX Ethernet switch. This arrangement allows field signals to be distributed closer to the equipment while keeping the safety logic in the central controller.
The is particularly useful in installations where field wiring needs to be distributed without moving the safety application into the remote I/O itself. HIMA explicitly states that the device extends the I/O level but cannot run a user program independently. That distinction is important during replacement because the /802 should not be treated as a standalone PLC CPU or safety controller.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
In a safety system, a remote I/O replacement is not simply a matter of matching the number of channels. The field wiring, line-monitoring configuration, SafeEthernet topology, controller project, firmware version, and safety certification all need to remain compatible. A module that powers up and communicates is not automatically a valid safety replacement.
Typical Applications
- Emergency shutdown systems: Digital field signals from trips, permissives, switches, and shutdown devices can be collected through distributed safety I/O.
- Process safety systems: Suitable for distributed digital signals in chemical, petrochemical, oil and gas, and other process installations.
- Turbine and power-generation protection: Can interface safety-related discrete field devices with HIMatrix/HIMax safety controllers.
- Railway safety systems: The F3 DIO 20/8 02 family is documented in HIMA material with applicable railway SIL 4 certification references.
Technical Pitfalls to Avoid
1. Do not call this a standalone safety PLC.
The is remote I/O. HIMA explicitly states that it cannot execute user programs independently; the safety application runs in the connected HIMax or HIMatrix controller.
2. Verify the exact firmware/software variant.
HIMA’s revision documentation identifies different device variants and firmware combinations. The F3 DIO 20/8 02 is available in configurations associated with SILworX and ELOP II Factory environments. Do not assume that every unit with the same basic hardware designation is interchangeable in every project.
3. Check SafeEthernet topology before replacement.
The module has two 100Base-TX ports with an integrated switch. Network cabling is part of the safety architecture, so port assignment, topology, controller configuration, and communication diagnostics should be recorded before removing the original device.
4. Line monitoring matters.
HIMA identifies the F3 DIO 20/8 02 as supporting line monitoring on its digital I/O. If the original application uses wire-break or short-circuit supervision, the field wiring and configured monitoring method must be reproduced correctly.
5. Do not substitute from channel count alone.
The HIMatrix family contains F3 DIO 8/8, F3 DIO 16/8, F3 DIO 20/8, and other variants. Similar physical construction does not establish functional or certification equivalence. HIMA’s technical list differentiates these modules by channel count and special features.
6. Verify the safety certificate for the actual installation.
The F3 DIO 20/8 02 is certified for high-integrity safety applications, but the applicable SIL/PL or railway classification depends on the system architecture and certification conditions. Do not use the module’s certification as proof that the complete safety function automatically achieves the same level.

Procurement Note
For /802 982200442, retain the complete identification F3 DIO 20/8 02 / /802 / 982200442 when sourcing a spare. Before installation, compare the hardware revision, firmware/software environment, controller type, SafeEthernet configuration, field line-monitoring settings, and applicable safety certificate.
This is a safety-related component, so functional testing after replacement should cover both the individual I/O channels and the complete safety function. A successful Ethernet connection alone is not sufficient evidence that the replacement is ready for service.
