The interface between PLC and electrical circuit is completed through the input and output part (I/O). The I/O module integrates the I/O circuit of the PLC, whose input register reflects the status of the input signal, and the output point reflects the status of the output latch. The input module converts electrical signals into digital signals and enters the PLC system, while the output module is the opposite. I/O is divided into switching input (DI), switching output (DO), analog input (AI), analog output (AO) and other modules.

Switching value refers to the signal with only two states of ON and OFF (or 1 and 0), while analog value refers to the continuously changing value. Common I/O classifications are as follows:

Switching value: 220VAC, 110VAC, 24VDC according to voltage level, and relay isolation and transistor isolation according to isolation mode.

Analog quantity: according to signal type, there are current type (4-20mA, 0-20mA), voltage type (0-10V, 0-5V, -10-10V), etc., and according to accuracy, there are 12bit, 14bit, 16bit, etc.

In addition to the above general IO, there are also special IO modules, such as thermal resistance, thermocouple, pulse and other modules.

The specification and number of modules are determined according to the number of I/O points. The number of I/O modules can be more or less, but the maximum number of I/O modules is limited by the ability of the basic configuration that the CPU can manage, that is, the maximum number of backplane or rack slots.
