4-channel Metering Control Type Auxiliary Module (Magnetically Held Relay)

JSY1054

Description:

4-channel metering and relay control module independently developed and designed by our company . This product is developed using advanced technologies such as digital sampling and processing technology and SMT technology. It has completely independent intellectual property rights and can accurately measure the voltage, current, power, power factor, energy and other electrical parameters in the AC power grid with a rated frequency of 50Hz. The module has a built- in RS485 communication interface and uses the MODBUS-RTU communication protocol . It can be easily connected to various AMR systems and has the characteristics of good reliability, small size, light weight, beautiful appearance and easy installation.

JSY1054 can be widely used in energy-saving transformation, electricity, ccommunications, railchannels, transportation, environmental protection, petrochemicals, steel and other industries to monitor the current and power consumption of AC equipment.

4-channel Relay Metering Control Module Detail:

Relay board features

- Collect 4-channel single-phase AC power parameters, including voltage, current, power, factor, frequency, electric energy and other electrical parameters.
- Adopting special measurement chip and effective value measurement method, the measurement accuracy is high.
- With 1 RS -485 communication interface and ESD protection circuit.
- The electric energy data is a 4- byte unsigned number and the data is saved when the power is off.
- The communication protocol adopts standard Modbus-RTU, which has good compatibility and is easy to program.
- DC12V power supply with anti-reverse connection protection function. The power module will not be damaged but will not work if connected in reverse.
- High isolation voltage, withstand voltage up to AC3000V.

Technical Parameters

AC input
