The JSH-40064A is a 6-channel AC power data acquisition module designed for multi-channel electrical measurement and monitoring.
It supports simultaneous measurement of AC voltage, AC current, active power, reactive power, power factor, energy, frequency and harmonics. Each input channel is independently isolated, providing reliable measurement in industrial environments.
The module uses a high-precision 24-bit ADC and 32-bit ARM MCU, with true RMS measurement and high linearity. It supports RS485 or Ethernet communication and is compatible with Modbus RTU and Modbus TCP, making it easy to integrate with PLCs, industrial PCs, monitoring systems and other host devices.
