a. The analog volume expansion module provides the function of analog input/output, with the following advantages:<br>Best adaptability: suitable for complex control situations;<br>b. Directly connected to sensors and actuators, 12-bit resolution and multiple input/output ranges can be directly connected to sensors and actuators without the addition of amplifiers, e.g. the EM235CN module can be directly connected to the PT100 thermal resistor<br>c. Flexibility: When the actual application changes, PLC can be extended accordingly, and it is very easy to adjust the user program.
