　　The 140CRS12420 I/O module, the input/output module, is an important part of the industrial automation system. Here is a detailed description of the I/O module:

　　Definition and classification:

　　The I/O module refers to the input/output module of the PLC (programmable logic controller), which is used to realize the connection between the PLC and the industrial production process.

　　Depending on their function and purpose, I/O modules can be divided into discrete, analog and special modules.

　　In the broader field of programming and application, I/O modules also include file I/O, byte stream I/O, buffered I/O, text I/O, socket I/O, serialized I/O, and memory-mapped I/O to meet different programming needs.

　　Functions:

　　Input module: Used to receive and collect input signals from various sensors, switches and transmitters, such as switching input signals and analog input signals. The input module also needs to convert these different level signals into digital signals so that the CPU can receive and process them.

　　Output module: 140CRS12420 receives the digital signal processed by the central processor and converts it into the signal that can be received by the field executive parts, such as the control signal of the contactor, solenoid valve, regulating valve, speed regulating device, etc., as well as the display or alarm signal of the indicator light, digital display and alarm device.

　　Features and applications:

　　Wide range of products: 140CRS12420 includes digital input/output module, analog input/output module, temperature acquisition module and high-speed counter module to meet various industrial needs.
