Overview
Intelligent combinationThe table has the following functions and features:
The full-scale display value, upper and lower limit alarm values, and communication address can be freely set through the buttons on the panel, making it very flexible and convenient to use.
● Optional analog transmission output, 4-20mA, 0-20mA, 4-12-20mA, 0-5V, 1-5V optional.
● Optional 2-channel alarm output for monitoring the upper and lower limits of the measured parameters.
Optional RS485 digital interface, using standard MODBUS-RTU protocol.
Adopting direct communication RMS effective value measurement, digital zero calibration, digital tuning, high accuracy, and extremely high cost-effectiveness.
