PCB Circuit Board | MPRC 086349-002 | ABB

Technical Specifications

The ABB MPRC 086349-002 is a plug-in PCB module for industrial control and measurement applications requiring stable power distribution and reliable signal processing. MPRC 086349-002 operates with a dual 24 VDC input voltage, providing a power source for continuous operation. It incorporates 1500 VAC galvanic isolation between electrical circuits, helping to separate control signals from external electrical interference.

Troubleshooting & Commissioning Checklist

Node ID Alignment: Confirm that the network station/node ID dip switches on the MPRC match the exact software address assigned in the QCS system architecture.
Sensor Standardization: Immediately execute a Standardization / Air-Gap Calibration routine from the operator station after replacing an MPRC board. This pushes the correct gain and offset coefficients from the host back into the board's local volatile RAM.

Field Engineering Considerations

The Standardization Protocol: Whenever an MPRC 086349-002 is swapped or re-seated, the local memory buffer loses its active offset calibrations.
Do Not Bypass Air-Gap Calibration: Field engineers must force the scanner to run a manual "Air-Gap Standardization" routine from the QCS workstation immediately upon power-up. Running the system without this step will cause the host software to apply default coefficients, resulting in completely inaccurate basis-weight or moisture readings that could ruin thousands of meters of product.

Technical FAQ

Q: If a newly installed MPRC 086349-002 displays a solid red ERROR LED for over 30 seconds, what does it mean?
A: It indicates a fatal hardware condition, such as a failed power-up self-test, local logic voltage degradation, or corrupted boot sector flash memory.

Q: Does the MPRC 086349-002 require a manual software calibration after being replaced in the field?
A: Yes, you must immediately execute an "Air-Gap Standardization" routine from the QCS workstation to push the sensor gain and offset coefficients back into the board's volatile RAM.

Q: How does the MPRC 086349-002 protect its delicate differential circuits from the humid, corrosive environment of a paper mill?
A: The entire printed circuit board is treated with a heavy layer of industrial conformal coating to resist moisture, conductive paper dust, and chemical vapor ingress.

Q: Do you supply brand-new, original parts or second-hand refurbished items?

A: Our stock consists of Original New items; all products undergo quality inspection to ensure they are fully functional.

Q: What guarantees are included with the shipment?
