Multi-Functional High-Precision Module MFHPM-1
Multi-Functional High-Precision Module MFHPM-1 is designed to produce 24-bit digital signals from three measurement channels that can be used for voltage, current, resistance values, and bridge measurement circuits. It also provides parameter outputs via a digital interface (RS 485) and control signals by two universal static discrete outputs.
Scope of application
MFHPM-1 is used when working with the sensors comprising an output proportional value of the measured values: differential and unipolar voltage up to +/- 30 V, including microstrain sources (thermocouples), signal current values 0 ... 20 mA, resistance 0..2000 Оhm (resistance temperature detectors) including bridge conversion diagrams (strain sensors) with a speed up to 500 samples per second. It generates discrete threshold signals of the measured value for automatic process control (e.g., P, PI, PID).
