Summary:
LU---S14013 is a RTD input module with three-channel of 16 bits A/D, can acquire two-wire, three wire, four-wire RTD input signal, and the RTD maybe PT10, PT100, PT200, PT500, PT1000, CU50, CU100 and so on. LU---S14013 has the function of cutoff detection. There is 3000VDC isolation voltage between analog input channels and the module, it effectively prevent the module from being scathed by high-voltage surge. LU---S14013 supports Modbus protocol, RS--485 communication, has built-in optical coupler and also has functions of surge protection, surge absorption, thunder-proof etc.
