3-channel Metering Control Type Auxiliary Module (Magnetically Held Relay)
JSY1123

Description:

The JSY1123 is a three- channel, single-phase metering control module independently developed and designed by our company. Developed using advanced technologies such as digital sampling and processing and SMT processes, this product boasts complete independent intellectual property rights and accurately measures voltage, current, power, power factor, and other electrical parameters in single-phase AC power grids with a rated frequency of 50Hz. The module features a built- in RS485 communication interface and utilizes the MODBUS-RTU protocol, making it easily compatible with various AMR systems. It boasts excellent reliability, compact size, lightweight, attractive appearance, and easy installation.

JSY1123 can be widely used in energy-saving transformation, electricity, communications, railways, transportation, environmental protection, petrochemical, steel and other industries to monitor the current and power consumption of AC equipment.
