Product Description

The BY194 series instrument can measure various commonly used power parameters, whether there is electricity or not, and the maximum demand. it also has multiple expansion function modules: digital communication module, digital switch module,electric energy pulse module, and analog ransmission and output module, which can be flexibly selected according to needs. All transmitted data can be read through the RS-485 communication port using the MODBUS protocol, and the switch input can be used to monitor the status of the switch; The output of the switching value can be remotely controlled and alamed when exceeding the limit; The analog transmission output function can replace traditional transmiters.

Wiring Method

Note: “*” refers to the specific wiring method of the current inlet terminal, please refer to the product’s random wiring diagram. Correct wiring is the first step in the corect use of an instrument. Pay attention to the matching of the external auxliary power supply and input signal with the model of the ordered instrument (such as auxiliary power supply voltage exceeding270v, do not use it as AC38oV for6kV/100V instruments). The wiring position should be correct, and special attention should be paid to not connecting strong current signals to weak current signals (such as communication, pulse output,etc.). Additionally, pay special attention to the input voltage The polarity of the current signal should be correct., When the polarily of the input signal is incorrect,it can lead to correct votage and current measurement data but incorrect power, resulting in incorrect measurement of electrical energy.Therefore, it is necessary to pay attention to the wiring of the instrument.
