Function & Feature

1. 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.
2. Have three channel digital inputs and optional RS485-Modbus communication functionality. Can
monitor the galvanically isolated DI signal and programmed the transducer with customized SCADA
software. Any of the measured parameters can be read out via the optional RS485-Modbus
connection.
3. QPPX also can be used to configure the connection to the measured circuit for single-phase,
three-phase three-wire, three-phase four-wire, balanced or unbalanced load. Can be connected to a
variety of measuring and control devices and systems, such as analogue meters, PLC, computers,
data loggers, digital instruments and telemetry systems.
4. Snap on to DIN rail 35 x 7.5 mm complies with DIN-EN 50022 BS 5584
