Summary:

LU-S14017 is analog input module with 8 fully differential channels of 16 bit A / D. It can acquire voltage, current and so on analog input signal. All channels have the function of input range programming, which provides a good performance/price ratio for industrial measurement and control applications. And there is 3000 V isolation between analog input channels and the module, it effectively prevent the module from being scathed by high-voltage surge. LU---S14017 supports Modbus protocol, RS--485 communication, has built-in optical coupler and also has functions of surge protection, surge absorption, thunder-proof etc.
