LU-S14024 4-ch Analog Output Module


LU---S14024 can offer 3 ranges output of 0 ~ 20 mA, 4 ~ 20 mA, -10V-+10 V, the resolution is 12 bits. May set voltage/current set rate and initial output through programming, change output level via communication. LU---S14024 simultaneity has 4 channel digital inputs that can be used as counter or act as transient response corresponding to each output. The counter may count the external low pulse, the max value is 65535, and the count value can be read by the host computer. The event counter will auto reset when the module restart or be re-electrified each time. The transient response may automatically control D/A output fault when the input digital changes. 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---S14024 supports Modbus protocol, RS--485 communication, has built-in optical coupler and provide 3000VDC isolation voltage. LU---S14024 also has functions of surge protection, surge absorption, thunder-proof etc.
