Vibro-meter MPC4 200-510-076-115 Machinery Protection Card

The Vibro-meter MPC4 200-510-076-115 is an advanced 4-channel machinery protection card designed for the VM600 series mechanical protection system. This module represents an enhanced evolution of the MPC4 product line, featuring improved firmware stability, expanded diagnostic coverage, and optimized performance for demanding industrial environments.

Measurement Architecture

The MPC4 provides four independent dynamic signal input channels for vibration monitoring, plus two speed input channels for rotational speed and phase reference measurements. Each dynamic channel supports IEPE accelerometers, velocity sensors, and eddy current proximity probes. The module performs simultaneous calculation of multiple measurement parameters, including overall amplitude, displacement, and velocity values, with programmable filtering options for each channel.

• Dynamic Channels: 4 independent inputs

• Speed Channels: 2 tachometer inputs

• Sensor Types: IEPE/ICP accelerometers, velocity sensors, proximity probes

• Frequency Response: 0.1 Hz to 10 kHz

• Dynamic Range: > 90 dB

• Diagnostic Coverage: Enhanced built-in self-test

• Firmware: Optimized for EMI immunity

• Compatibility: Direct replacement for 200-510-076-114 versions

Alarm and Protection Functions

The module provides programmable alert and danger alarm setpoints for each measurement parameter. Alarm logic includes configurable time delays, hysteresis settings, and latching or non-latching operation modes. Alarm status is communicated to the system controller for relay activation and integration with plant safety systems. The module supports SIL 2 safety integrity level certification for applications requiring enhanced functional safety.

Diagnostic Capabilities

Continuous sensor integrity monitoring detects open circuits, short circuits, and sensor bias failures. The enhanced self-test circuitry provides improved fault detection coverage compared to previous versions. Front panel LEDs indicate channel status, alarm conditions, and module health. Buffered raw signal outputs on the front panel allow connection of portable analyzers for detailed signal analysis without interrupting system operation.
