Inputs Analog Inputs Some CPUs can be set to either analog or digital for use in the Rievtech Micro PLCs are available with analog inputs too. PLC program. They will be recognized as analog inputs when the input terminal is connected with an analog function block, and they will analog input interfaces are available for either 0-10VDC, 0-20mA or PT100. be recognized as switching inputs when the input terminal is not connected with an analog function block. Analog inputs are normally used to connect to transducer outputs.
Such transducers measure some physical parameter, such as Full range analog signals will convert to a value between 0 and 1000 (10 bits) for inputs on CPU and to a value between 0 and 512 pressure, temperature, liquid level, position, pH level, or other such continuously variable measurement. The transducer signal output (9 bit) for expansion modules. should be connected to a signal input on the PLC analog input channel and the transducer return or ground reference line must be Scale function in xLogicSoft can be used to automatically convert connected to the PLC common. the signal value to meaningful data.
