describe

MPC4 machine protection card is the core component of the VM600 machine protection system of Vibro-Meter company.

This flexible card can measure and monitor four dynamic signal inputs and two speed/phase signal inputs at the same time. When the dynamic signal is input.

Fully programmable, can receive acceleration, speed and displacement signals or other signals. Multi-channel processing technology on the board can realize various physical measurements, such as relative

Shaft vibration, absolute shaft vibration, SMAX, eccentricity, shaft displacement, absolute and relative expansion, dynamic pressure, etc. The speed/phase input can be connected with various speeds.

Sensors (such as eddy current, reluctance, TTL, etc.) support fractional speed ratio.

MPC has powerful digital processing functions, including digital filtering, digital integration or differentiation, and digital modulation (root mean square, average, peak value, peak-to-peak value, etc.).

Frequency order tracking (amplitude and phase) and sensor gap measurement.

The output unit is set in metric or English software, and the alarm and shutdown values are completely programmable, including alarm delay, dead zone and maintenance. Alarm and shutdown can also be set.

It is defined as an adaptive function of speed or any other external information, which is used to automatically multiply the trip value of the unit when it passes the critical point.

Analog 0-10V or 4-20mA is optional, and it is output from the supporting IOC4T card. The switch value can be made use of the supporting IOC4T self-contained relay, or its

Its slot RLC16 and IRC4 relay cards output.

MPC4 card has self-checking function, and has built-in sensor OK monitoring and channel fault and alarm status monitoring, which can judge the sensor, preamplifier,

Cable failure, channel failure, alarm, etc., and displayed on the LED indicator on the front panel of MPC4.
