Summary:

LU - S14021 can offer 3 ranges output of 0 ~ 20 mA, 4 ~ 20 mA, 0-10 V, the resolution is 12 bits. May set voltage/current set rate and initial output through programming, change output level via communication. 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---S14021 supports Modbus protocol, RS--485 communication, has built-in optical coupler and provide 3000VDC isolation voltage. LU---S14021 also has functions of surge protection, surge absorption, thunder-proof etc.
