Description
DEIF IOM 230 | CAN Bus Analog Output Expansion Module
Product Introduction
When a genset controller needs additional analog control outputs, the expansion module has to match both the controller and the connected governor or voltage regulator. Output range and load-sharing configuration are not minor details; they determine whether the replacement can interface correctly with the existing control loop.
The DEIF IOM 230 (2912890200-02) is a CAN bus analog-output expansion module in the IOM 200 series. It provides governor and AVR outputs, plus P and Q load-sharing interfaces for supported applications. DEIF identifies the IOM 230 for use with controllers including the AGC 150, AGC-4 Mk II, AGC-4, and iE 150 family, subject to application-specific functionality.
For maintenance and procurement teams, the IOM 230 should be matched by exact item number and configured output requirements. Confirm the controller model, CAN ID, output selector settings, and load-sharing application before approving it as a replacement.

Global Sourcing & Live-Test SOP
The following is a recommended qualification process. It does not imply that the specific unit being offered has been tested or refurbished.
Incoming Verification
- Confirm the IOM 230 model and OEM item number 2912890200-02.
- Record serial number and hardware revision, if available.
- Photograph the nameplate, terminal block, DIP switches, and enclosure.
- Inspect for damaged terminals, corrosion, contamination, and signs of unauthorized repair.
- Compare the unit with the removed module and approved site documentation.
Authenticity and Traceability
- Record supplier, purchase order, received condition, and shipment details.
- Check consistency between the label, item number, and supplied documentation.
- Request traceability or service records when available.
- Flag discrepancies in item number or revision for engineering review.
Functional Qualification
- Test using an approved DEIF-compatible setup and applicable OEM procedures.
- Verify module power-up and status indication.
- Confirm CAN bus communication with the intended controller.
- Test GOV and AVR outputs against the required configured ranges.
- Where applicable, validate P/Q load-sharing outputs using an approved test setup.
- Record CAN ID, DIP-switch settings, controller model, test equipment, and results.
Extended Run and Diagnostics
- Perform an extended operating run where supported by the test setup and procedure.
- Record test duration, diagnostic status, and environmental conditions.
- A 24-hour run may be included in a qualification plan, but must not be claimed as completed without supporting records.
Configuration and Packaging
- Record output selector and CAN ID switch settings.
- Document known differences from the removed unit.
- Package in ESD-safe materials with suitable mechanical protection.
- Include test or inspection reports only when those activities have actually been completed.
Field Engineer’s Pitfall Guide
- ❗ Do not overlook the output selector switches. The IOM 230 supports current and voltage ranges, but the selected range must match the receiving governor, AVR, or control input. Verify the DIP-switch settings before energizing the interface.
- ❗ Do not assume P/Q load-sharing functionality across every controller. DEIF documents P/Q load-sharing outputs for AGC 150 and AGC 200 applications. Confirm controller support and configuration before commissioning.
- ❗ Do not ignore CAN ID and shield termination requirements. Set the module ID according to the system design. DEIF’s documentation specifies that the CAN cable shield should be connected to the IOM/AGC GND terminals—not indiscriminately bonded to ground. Follow the applicable wiring manual.
Intent-Driven FAQ
Q1: What is the DEIF IOM 230?
It is a CAN bus analog-output expansion module from DEIF’s IOM 200 series, designed for genset regulation and power-management applications.
Q2: What outputs does the IOM 230 provide?
It provides governor and AVR analog outputs, along with P and Q load-sharing outputs for supported applications.
Q3: What output ranges are supported?
The documented selectable ranges include ±25 mA, 0–20 mA, ±12 VDC, and 0–10 VDC. The selected range must match the receiving equipment.
Q4: Which DEIF controllers can use the IOM 230?
The IOM 200 series is listed for iE 150, iE 150 Marine, AGC 150, AGC-4 Mk II, and AGC-4 controller families. Exact functionality, particularly P/Q load sharing, depends on the controller and application.
Q5: Does the IOM 230 communicate over CAN bus?
Yes. The module communicates with supported DEIF controllers through CAN bus. CAN ID and wiring must be configured according to the system documentation.
Q6: Is the IOM 230 hot-swappable?
Do not assume so. Follow the applicable DEIF controller and IOM maintenance procedure, including power isolation and site safety requirements.
Q7: Does the part number guarantee a tested unit or warranty?
No. Testing, warranty coverage, condition, and included accessories must be confirmed from the seller’s specific offer and supporting records.
