Summary:

LU - S14018 is T.C input module with 8 channels of16 bit A / D, may acquire voltage, current and J, K, T, E, R, S, B and so on T.C input signal, has the function of cold-junction compensation. 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---S14018 supports Modbus protocol, RS--485 communication, has built-in optical coupler and also has functions of surge protection, surge absorption, thunder-proof etc.
