QPPX Programmable transducer

QPPX electrical transducer measures a wide range of electrical parameters and generates analog or digital output signals suitable for interfacing with instrumentation and control systems. Total four channel output with panel key or PC control programmable user can free to set 4 different data from max 26 electrical parameter for sampling and analog signal output.

Have three channel digital inputs and optional RS485-Modbus communication functionality. Can monitor the galvanically isolated AO signal and programmed the transducer with customized SCADA software. Any of the measured parameters can be read out via the optional RS485-Modbus connection.
