Product Introduction

The VIBRO-METER VM600 MPC4 is a core processing card for the VM600 Machinery Protection System. It provides continuous online monitoring for critical rotating equipment such as steam turbines, gas turbines, compressors, generators, and large pumps.

The MPC4 accepts up to four programmable dynamic signal inputs and two tachometer inputs, performing DSP-based measurement of relative/absolute vibration, shaft position, eccentricity, thrust position, casing expansion, and dynamic pressure. It must be paired with an IOC4T card to form a complete card pair for sensor power, relay outputs, and analog signal routing.

Note: The exact part number must be confirmed from the nameplate. Common MPC4 variants include 200-510-070-113, 200-510-078-115, 200-510-111-034, and 200-510-111-035, which may differ in firmware, SIL certification, or channel configuration.

Quality Control Process (Dynamic for Protection Card)

• Nameplate verification: Confirm exact PNR, hardware revision, firmware, and SIL/standard version.
• Connector inspection: Check front-panel BNC, LED indicators, and backplane pins for damage or corrosion.
• IOC4T pair check: Verify the paired IOC4T card revision and relay configuration match the original setup.
• Power-up test: Seat in a compatible VM600 rack and confirm normal LED behavior and backplane detection.
• Channel validation: Verify dynamic and tachometer channel recognition via VM600 MPSx software.
• Packing: Use anti-static bag, connector caps, foam support, and rigid carton for shipment.

Replacement Pitfall Guide

❗ Do not install MPC4 without its paired IOC4T card. The MPC4 relies on the IOC4T for sensor power, relay outputs, and analog signal routing.

❗ Do not assume all MPC4 suffixes are interchangeable. Variants such as 200-510-070-113, 200-510-078-115, and 200-510-111-034 may differ in firmware, SIL certification, or channel configuration.

❗ Verify firmware compatibility with the installed VM600 MPSx software version. A mismatch can prevent configuration download or cause alarm logic errors.

❗ Record all alarm setpoints, filter settings, and channel mappings before removal. Restoring configuration from scratch risks incorrect trip thresholds.

❗ Check whether the original card is Standard, Separate Circuits, or SIL version. SIL-certified applications require a matching SIL replacement.

❗ Distinguish MPC4 from MPC4SIL. MPC4SIL supports a subset of SIL-rated measurements and may have different channel or certification constraints.

Keep these in mind and you’ll cut 90% of rework time.
