Description
Core Product Summary
The HIMA F3 DIO 20/8 02 (982200484) is a safety-related digital remote I/O module in the HIMatrix product family. It collects discrete field signals and transfers input states to a connected HIMax or HIMatrix controller through SafeEthernet. The controller sends output commands back to the module for switching connected field devices.
This model provides 20 digital inputs and 8 digital outputs in a compact metal housing. The order number 982200484 identifies the SILworX version. It is intended to extend the I/O capacity of a compatible HIMA safety-control architecture; it does not execute the user safety program independently.

Engineering Selection Highlights
digital inputs and 8 digital outputs
The module combines discrete signal acquisition and output switching in one remote I/O unit. This configuration can reduce the need to distribute digital I/O across multiple modules when the field signal count matches the available channels.
Safety-related communication with HIMA controllers
Input values are transmitted to a connected HIMax or HIMatrix controller over SafeEthernet. Output values are assigned by that controller and delivered to the remote I/O module through the same safety communication architecture.
SILworX version identification
Order number 982200484 is associated with the SILworX version of the F3 DIO 20/8 02. Software environment and operating-system compatibility should be confirmed against the installed controller, firmware, and project configuration before a replacement is approved.
Diagnostic functions for discrete circuits
The module supports configurable line monitoring for applicable input circuits. Correct diagnostic behavior depends on the selected configuration and field wiring; line monitoring should not be assumed to be available for every circuit arrangement.
Defined environmental and installation limits
The module is specified for an operating temperature range of 0°C to +60°C and an IP20 enclosure rating. It is intended for installation in a suitable control cabinet rather than direct exposure to water, dust, or other uncontrolled environmental conditions.

System Compatibility & Integration Requirements
The F3 DIO 20/8 02 is a remote I/O component, not a standalone safety controller. Selection and commissioning require confirmation of the following:
- Controller compatibility: Confirm the target HIMax or HIMatrix controller supports the module and the intended SafeEthernet architecture.
- Engineering software: Match the module variant and controller operating-system version to the correct engineering environment. The 982200484 version is associated with SILworX.
- Project configuration: Verify the configured channel assignments, input interpretation, output behavior, and diagnostic settings before transferring the project to the operating system.
- Network configuration: Check SafeEthernet communication settings and the physical Ethernet connections against the system design.
- Power supply: Provide a compatible 24 VDC supply within the specified tolerance and account for the maximum-load current requirement.
- Field wiring: Verify input and output polarity, grounding, protective devices, load current, and the wiring method required for the selected diagnostic functions.
- Safety validation: Confirm the complete application—including controller, I/O, wiring, software, and safety function—meets its required safety integrity and performance targets.
Do not assume that a module with the same base model but a different order number uses the same software version or configuration requirements.
Dimensions, Mounting & Connection Notes
The published maximum dimensions, excluding plugs, are:
| Dimension | Maximum value |
|---|---|
| Width, including enclosure screws | 207 mm |
| Height, including fixing bolt | 114 mm |
| Depth, including earthing screw | 66 mm |
The module is mounted horizontally on a 35 mm DIN rail. Allow additional cabinet space for plugs, Ethernet cables, field wiring, earthing, and maintenance access.
Before installation:
- Isolate the relevant power sources and follow the site’s safety procedures.
- Confirm that the DIN rail, cabinet layout, and grounding arrangement meet the installation requirements.
- Check the terminal assignments and wiring diagrams for the exact module variant.
- Verify the 24 VDC supply polarity, protective fuse, and expected load current.
- Inspect the Ethernet connections and confirm the intended controller communication path.
- Complete configuration checks, functional testing, and the required safety validation before returning the system to service.
The enclosure is rated IP20. Any installation in a potentially explosive atmosphere or other restricted environment must follow the conditions and additional measures specified in the applicable HIMA documentation.
Detailed Product Overview
Digital signal acquisition and output control
The HIMA F3 DIO 20/8 02 provides 20 digital inputs and 8 digital outputs for discrete field interfaces. Input signals are evaluated by the remote I/O module and transmitted to the connected safety controller. Output states are assigned by the controller and delivered to the module over SafeEthernet.
This separation between remote signal handling and application logic allows the module to extend the I/O capacity of an existing compatible HIMA system without acting as an independent user-program execution unit.
Output current and load considerations
The eight outputs do not all have identical current limits. Channels 1–3 and 5–7 are rated for up to 0.5 A each at the maximum ambient temperature. Channels 4 and 8 have higher specified limits: up to 1 A, or up to 2 A when ambient temperature does not exceed 50°C.
Output selection must account for the actual load, ambient temperature, wiring, and the device’s protection behavior. The module’s overload response and automatic recovery behavior should be checked against the applicable manual when designing or troubleshooting output circuits.
Diagnostics and fault handling
Configurable line monitoring can support detection of wiring faults on applicable input circuits, including selected short-circuit and open-circuit conditions. The effectiveness of these diagnostics depends on correct circuit design, wiring, and configuration.
During commissioning or replacement, verify channel status, controller communication, configured diagnostics, and the intended safe-state response. A successful network connection alone does not establish that the safety function is operating correctly.
Replacement and maintenance planning
When replacing an installed unit, verify the full model designation and order number rather than matching only the abbreviated F3DIO20802 label. Confirm the SILworX variant, controller and operating-system compatibility, project configuration, terminal wiring, and required proof-test procedures.
A replacement should not be returned to operational service until the applicable functional checks and safety validation have been completed by qualified personnel.
Applications & System Role
The F3 DIO 20/8 02 is intended for safety-related discrete signal interfaces in compatible HIMatrix and HIMax control systems. Its suitability depends on the application design, controller configuration, field-device characteristics, and required safety assessment.
Typical system functions may include:
- Emergency shutdown interfaces: Acquisition of discrete status signals and switching of safety-related outputs as commanded by the configured safety controller.
- Safety interlocks: Monitoring switch or contact states and transmitting input information to the controller for interlock logic.
- Process equipment protection: Providing digital interfaces between field devices and a HIMA safety-control system.
- Distributed safety I/O: Extending the digital I/O level where remote placement and SafeEthernet communication are supported by the system architecture.
The module does not determine the safety function by itself. The safety response depends on the complete system design, application logic, wiring, diagnostics, and validation.
