The module operates from 24 VDC ±10%, with a maximum stated current of 0.14 A. Its internal isolated supply is ±12 VDC. The documented mechanical size is 220 mm × 100 mm × 30 mm, corresponding to a 6TE rack module.
Application Scenarios & Pain Points
A refiner position-monitoring fault is rarely something to ignore. If the position signal moves outside its configured limit, the control system needs to know immediately; a missing or incorrect signal can also lead technicians toward the wrong mechanical diagnosis.
Typical Applications
- Refiner Rotor Position Monitoring: The POM-RM1 measures position information associated with the refiner monitoring system and evaluates it against configured limits.
- POT-50 Transducer Interface: The module is designed to work with the POT-50 position transducer. The RMS documentation specifically lists this sensor alongside the POM-RM1.
- PLC Limit Monitoring: Three independently adjustable digital outputs—LIMIT 1, LIMIT 2, and LIMIT 3—can be connected to PLC inputs for process or protective logic.
- RMS-EX1 Rack Systems: The module occupies an internal position within the RMS-EX1 architecture alongside vibration, motor-power, hydraulic-pressure, and other monitoring modules.
Field Case:
When a position alarm appears intermittently, check the transducer and cable before replacing the POM-RM1. A damaged POT-50 connection can produce a drifting or noisy signal that looks like a monitor-board problem. Also verify the three limit adjustments before commissioning a replacement; changing them blindly can alter the machine’s alarm behavior.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do Not Confuse With Other RM1 Monitoring Cards
The RMS rack contains several modules with similar physical formats—VIM-RM1, MPM-RM1, HPM-RM1, OTM-RM1, LDU-RM1, and . Their functions are different.
How to avoid it: Specify all three identifiers during procurement: + VAL0123032 + SKC9068249.
⚠️ Check the Before Blaming the Monitor
The depends on the external position transducer and cable. A poor connection can create symptoms resembling monitor-board failure.
How to avoid it: Check the , K-POT25 cable, connector pins, excitation/reference voltage, and signal stability before replacing the PCB.
⚠️ Preserve the Three Limit Settings
The module uses three 15-turn potentiometers for its limit settings. The documentation specifies separate LIMIT 1, LIMIT 2, and LIMIT 3 functions.
How to avoid it: Photograph and record the original settings before removing the old module. Do not assume a replacement board’s potentiometer positions are suitable for the machine.
Frequently Asked Questions (FAQ)
What is Dametric VAL0123032?
It is a Position Monitor module for the RMS/RMS-EX1 refiner monitoring system. The documented cross-reference is / Metso VAL0123032 / SKC9068249.
What sensor does use?
The RMS documentation identifies the as the associated POM position transducer, with VAL0103227 / SKC9069808 as its corresponding identifiers.
The connection is not something I would substitute casually. Verify the sensor model and cable arrangement before changing the monitor.
What are the outputs of the ?
The module provides three digital limit outputs: LIMIT 1, LIMIT 2, and LIMIT 3. The documented output circuit uses optically isolated P-channel FETs connected to the RMS system voltage, with a stated maximum current of 0.1 A.
What power supply does require?
The documented supply is +24 VDC ±10%, with a maximum current of 0.14 A. Internally, the module provides an isolated ±12 VDC supply.
Can I replace with another RMS-RM1 module?
No. Similar-looking RMS modules perform different jobs. A VIM-RM1 handles vibration monitoring, HPM-RM1 handles hydraulic pressure, and MPM-RM1 handles motor power, while is specifically the position monitor.
The replacement should match / VAL0123032 / SKC9068249.
What should I request when buying a refurbished ?
Request:
- Actual front and rear photographs
- marking
- identification
- SKC9068249 identification
- Connector-condition photographs
- 24 VDC power-up test
- input simulation or functional test
- LIMIT 1/2/3 output verification
- Potentiometer inspection
- LED indicator test
- ESD-safe packaging
- Warranty terms
For this module, a meaningful test should exercise the position input and all three limit outputs, not merely confirm that the board powers up.
What is the main procurement risk?
Buying the correct-looking RMS module but the wrong function. The RMS-EX1 rack contains several closely related monitoring modules, so the complete cross-reference / / SKC9068249 should be included on the purchase specification.
