ALMEMO® input connector, also for existing sensors, see chapter ALMEMO® input connectors. ALMEMO® standard plug • The ALMEMO® measuring system makes it possible to process four channels per measuring input - depending on the sensor and the measuring instrument. • The ALMEMO® plug incorporates 6 screw terminals - 2 for the sensor‘s power supply and 4 for its measuring signal. • With Pt100 sensors using 4-conductor circuitry all 4 free connections will be required for the measuring signal. Only one sensor of this type can be connected therefore per measuring input. • Electrical signals only require...
