8 Channels DC Power Monitoring Module Modbus RS485
JSY-MK-218 DC 8-channel power monitor is a multi-channel DC collector that can complete electric energy collection, measurement and data transmission. It can accurately measure 8-way DC voltage, current, power, electricity and other electrical parameters. With RS-485 communication interface and MODBUS-RTU protocol, has excellent cost-effectiveness.
JSY-MK-218 can be widely used in industries such as energy-saving renovation, power, communication, railway, transportation, environmental protection, petrochemical, steel, etc., to monitor the current and power consumption of DC equipment.
Features:
1. Capture 8 channels DC parameters such as voltage, current, power, and electricity etc.
2. Adopting dedicated measuring chips and effective value measurement methods, with high measurement accuracy.
3. With RS-485 communication interface.
4. Standard Modbus-RTU communication protocol, which has good compatibility and is convenient for programming.
5. RS-485 communication interface with ESD protection circuit.
6. Wide working voltage DC9-50V.
7. High isolation voltage, withstand voltage up to DC1000V.
