LU-S14016 Analog Input/Output Module

Summary:

LU-S14016 offers input acquisition of single-channel strain gage mV/mA signal, output of single-channel driving voltage 0-10V. The A/D input optical isolation, D/A output optical isolation and more than 3000V power isolation, may effectively prevent from ground looping and high-voltage surging. LU-S14016 also offers 4 channel digital outputs, Open-Collector Outputs(with max. load) is 30 V，30 mA. The digital outputs can control SSR, accordingly control heater, pump and other electronic device. Channel 0 & 1 digital output also have the function of upper limit and lower limit alarm, and the threshold value is downloaded to EEPROM of the module from the host computer. The alarm function can be remotely controlled to be allowable or prohibitive, when it is enabled, the digital output channel-1 will show the state of upper limit alarm, and the digital output channel-o will show the lower limit alarm state. LU-S14016 supports Modbus protocol, RS-485 communication, has built-in optical coupler and provides 3000VDC isolation voltage. LU-S14016 also has functions of surge protection, surge absorption, thunder-proof etc.
