8-Way DC Power Metering Module Modbus Direct Current Capture PCBA &Voltage Collecting Module
JSY-MK-238 is a real-time measurement and acquisition module for 8-channel DC voltage (or current) signals. It uses linear optocoupler isolation to achieve isolation between each channel signal. The signal measurement adopts a multi-channel 24 bit high-precision AD measuring chip, which can achieve universal detection of AC and DC signals with high accuracy, good stability and fast sampling speed. With standard RS485 bus MODBUS-RTU protocol. Can be widely used in industries such as photovoltaic energy system, aging testing equipment, production automation testing and computer room monitoring etc.
Features:
1. 8-channel DC voltage, current or voltage current combination measurement, can be used for both AC and DC purposes.
2. Fast speed, can complete the collection of 8-channel data in 200ms.
3. High accuracy, using multi-channel 24 bit AD, linear measuring range is up to 0.5%.
4. Wide power supply 9-28VDC.
5. High reliability, each channel is isolated from each other. The power supply and communication are completely isolated from the tested ends, withstand voltage 2500V.
6. Two optional ways to set the address: hardware DIP switch and software with baud rate.
7. 16mm large spacing plug-in terminals, convenient wiring.
