power grid with high precision, and optional with RS485
communication function and upper and lower limit alarm function. It
has the characteristics of easy connection and installation, simple
wiring, convenient maintenance, small engineering amount, field
programmable setting input parameters, etc., and can complete the
network communication of PLC and industrial control computer
different from the industry.
PeculiarityMeasurement: single phase current
Display: a row of LED digital tube display, high visibility
Communication: RS485 communication, MODBUS-RTU communication
protocol (optional)
Output: Two relay outputs (optional)
Expansion: Input signal can be directly from the current and
transformer, and the input parameter ratio can be programmed on
site
Application: Suitable for power grid, automatic control system,
mainly measure the current parameters in power grid
