VIBRO METER VM600 MPC4 200-510-070-113 Machinery Protection Card
This versatile machinery protection card is capable of measuring and monitoring up to four dynamic signal inputs and up to two speed inputs simultaneously. The dynamic signal inputs are fully programmable and can accept signals representing acceleration, velocity, displacement (proximity), and other physical parameters.
On-board multi-channel processing allows measurement of relative and absolute vibration, Smax, eccentricity, thrust position, absolute and differential housing expansion, displacement, and dynamic pressure. Digital processing functions include digital filtering, integration or differentiation, rectification (RMS, mean value, true peak, or true peak-to-peak), order tracking (amplitude and phase), and measurement of the sensor-target gap.
The speed (tachometer) inputs accept signals from a variety of speed sensors, including proximity probes, magnetic pulse pick-up sensors, or TTL signals, with support for fractional tachometer ratios. Configuration can be expressed in metric or imperial units, with fully programmable Alert and Danger set points, as well as alarm time delay, hysteresis, and latching. The Alert and Danger levels can also be adapted according to speed or external information.
Each alarm level provides a digital output internally via the corresponding IOC4T input/output card, which can drive four local relays on the IOC4T or be routed via the VM600 rack's Raw bus or Open Collector (OC) bus to optional relay cards such as the RLC16 or IRC4. The processed dynamic and speed signals are also available as analog output signals on the rear of the rack (front panel of the IOC4T), in both voltage-based (0-10 V) and current-based (4-20 mA) formats.
Self-Testing & Diagnostics
The MPC4 performs a self-test and diagnostic routine on power-up, and its built-in "OK system" continuously monitors the level of signals from the measurement chain (sensor or signal conditioner), indicating any broken transmission line, faulty sensor, or signal conditioner. An LED on the MPC4 front panel indicates whether a processing or hardware error has occurred, while six additional LEDs (one per input channel) show whether the OK System has detected a fault or an alarm on the channel.
The MPC4 card is available in three versions: a standard version, a separate circuits version, and a safety (SIL) version, all of which operate as a card pair with the corresponding IOC4T input/output card.
