Summary:
LU-S14011 has the functions of measuring range adjustment, A/D conversion, isolating, signal conditioning, data comparing and RS-485 communication. The input signal may be T.C of type J、K、T、E、R、S、B, voltage and current and so on. When with T.C input, LU-S14011 has cold-junction compensation function. In addition, LU-S14011 also offers one digital input and two digital outputs. The event counter connect with the digital input channel, it can count the external low pulse, the max. count 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 two digital outputs 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. The optical isolation and voltage isolation of A/D input is up to 3000V so that it will be effective to prevent from ground looping and high voltage surging. LU-S14011 supports Modbus protocol, RS-485 communication, has built-in optical coupler and also has functions of surge protection, surge absorption, thunder-proof etc.
