The module consists of two identical channels, electrically isolated from each other and from the power supply. Each channel has an oscillator that supplies the transducer with AC excitation, inputs for the two position sensitive signals from the transducer and an adjustable signal amplifier with current and voltage output. Calibration of LVD 3 and the connected LVDT transducers is easily performed by switches, potentiometers and test sockets on the module. LVD 3 is mounted on a DIN rail or any flat surface. All electric connections to the module are made through one plug-in terminal block for each channel. APPLICATIONS PLC 0-10 VDC, +/-10 VDC 4-20 mA 24 VDC Position transducer type LVDT
