Din Rail 16 Channel DI/DO/AI/AO ModBus RTU

The device realizes the conversion between 16-channel digital quantity (DI/DO), analog quantity (AI/AO) modules and MODBUS RTU. The digital quantity, analog quantity signals and RS485 communication electrical signals are isolated from each other, effectively suppressing various series mode and common mode interference, ensuring the accuracy of data, and also ensuring the reliable operation of the module.
