Description
Product Overview
The HIMA F60MI24014 982400006 is identified with the HIMatrix F60 safety-related input module family. The corresponding MI 24 01 module is designed to acquire field signals for safety-related control applications. Its 24 input channels can be configured for analog current measurement or digital signal evaluation. Analog applications use 0/4–20 mA transmitter signals, while digital applications support suitable proximity switches and resistor-wired contacts. These two operating modes are alternatives at the channel-configuration level; analog and digital input functions cannot be used simultaneously on the same channel.
In an F60 safety system, the MI 24 01 provides the field-signal interface between process instruments and the safety controller. Typical signals include pressure, temperature, and flow transmitter outputs, as well as proximity-switch and contact status. The module provides diagnostic information that the application program must evaluate alongside the measured or digital input values. HIMA documentation identifies the module for safety-related applications up to SIL 3, Category 4, and Performance Level e. These ratings apply within the specified system architecture, configuration, and application requirements; they should not be treated as a standalone guarantee of the safety integrity of an entire installation.
The HIMA F60MI24014 982400006 identification should be checked against the physical type label before ordering a replacement. The documented MI 24 01 module uses a 24 VDC supply and installs in the modular F60 subrack. Its analog inputs are non-galvanically isolated, making correct grounding, shielding, transmitter wiring, and external circuit design important during commissioning. The manual also specifies different supply-output arrangements for transmitter groups. A replacement should therefore be checked against the installed module’s hardware revision, channel configuration, terminal wiring, and engineering project rather than selected by the model string alone.
Product Introduction
A safety controller can report incorrect process conditions if field transmitters are wired or configured incorrectly. Input-channel selection, transmitter supply, and diagnostic handling must all match the approved application design.
The HIMA MI 24 01 provides 24 configurable input channels for current signals or compatible digital devices in a modular HIMatrix F60 system. Before replacing a unit identified as F60MI24014 982400006, verify the type label and compare the installed configuration with the replacement documentation.

Major Features and Engineering Considerations
24-Channel Configurable Input Design
The MI 24 01 supports 24 input channels that can be configured for analog current measurement or digital signal evaluation. This allows a single module type to serve different instrument-interface requirements within the F60 system. Channel configuration must match the connected field device.
Analog Current Measurement
The analog inputs are designed for 0/4–20 mA current signals. The documented 12-bit resolution and specified measurement accuracy should be considered when evaluating transmitter scaling, alarm thresholds, and process measurement requirements.
Digital Signal Evaluation
Digital operation supports compatible proximity switches and contacts wired with resistors. Input thresholds and diagnostic limits must be configured and verified for the actual field device. A standard dry-contact connection should not automatically be treated as equivalent to a resistor-supervised contact circuit.
Transmitter and Sensor Supply
The module provides grouped supply outputs for external field devices. Each of the three groups covers eight channels and has a maximum total current of 200 mA. The supply can be configured for 8.2 VDC or 26 VDC. Exceeding the group current limit can shut down the associated supply outputs, so the combined transmitter load must be calculated before commissioning. Vogi International
Diagnostic Information
The module provides error information for analog and digital input channels. The application program must evaluate the corresponding diagnostic information rather than relying only on the reported process value. This is particularly important in safety-related applications where an input fault must trigger the intended safety response. Vogi International
Field Wiring Requirements
HIMA specifies shielded, twisted-pair wiring for analog and digital inputs. The manual also provides grounding guidance and limits for total circuit resistance. Incorrect shielding, transmitter supply selection, or external wiring can affect measurement performance and may damage the input circuit. Vogi International

Frequently Asked Questions
Q1: What is the main function of the HIMA F60MI24014 982400006?
The supplied identification points to the HIMA HIMatrix MI 24 01 input-module family. The documented module provides 24 configurable channels for analog current signals or compatible digital field devices.
Q2: Does the MI 24 01 support 4–20 mA transmitters?
Yes. The manual specifies 0/4–20 mA analog input applications, with a nominal measurement range of 0–20 mA.
Q3: Can analog and digital signals be used simultaneously?
The module supports both input types, but analog and digital functions cannot be used simultaneously on the same channel. Each channel must be configured according to its connected field device.
Q4: Can I hot-swap this module while the safety controller is running?
Do not assume hot-swap capability. The MI 24 01 manual describes removing the terminal plugs and releasing the module’s retaining screws before extraction. Follow the site’s approved shutdown and maintenance procedure and verify the system-level replacement instructions before removing the module.
Q5: Does this module support firmware v3.1?
A general firmware-v3.1 compatibility claim cannot be confirmed from the available MI 24 01 documentation. Compatibility depends on the F60 central module, operating-system version, engineering software, and configured project. Verify the installed system revision before replacement.
Q6: Is the module certified for SIL 3 applications?
The documented MI 24 01 is certified for safety-related applications up to SIL 3, Category 4, and PL e. The complete safety function must still be validated against the applicable system certificate, architecture, application program, and safety requirements.
Q7: Is 982400006 the confirmed HIMA order number for MI 24 01?
Not from the documentation reviewed. HIMA manual HI 800 209 E lists MI 24 01 under part number 982200115. The supplied number 982400006 should be checked against the original type label and purchasing records before ordering.
Procurement and Maintenance Considerations
Before purchasing a replacement, request a clear photograph of the complete type label showing the product name, part number, hardware revision, firmware revision, and production information.
For an installed MI 24 01, check the following:
- Confirm that the module belongs to the modular HIMatrix F60 system.
- Compare the original and replacement hardware revisions.
- Verify the 24-channel configuration and analog/digital channel assignments.
- Confirm transmitter supply voltage selection and group current loading.
- Check field wiring, shielding, grounding, and terminal assignments.
- Verify the F60 controller operating system and engineering-software compatibility.
- Request functional test evidence and a clear description of the unit’s condition.
Important procurement point: Do not approve a replacement solely because a seller lists F60MI24014 and 982400006 together. The manufacturer documentation reviewed identifies MI 24 01, but its listed part number differs. Resolve that identification discrepancy before installation in a safety-related system.
