Digital/analog input module difference According to the difference of field input signal, the input module can be divided into switching input module and analog input module. The function of the switching input module is to convert various switching signals into TTL standard signals required by the CPU. According to the input power supply type, it can be divided into DC input module and AC input module. The input signal is converted into TTL (5V) standard signal by photoelectric coupling after voltage division, current limiting and filtering. The function of the analog input module is to convert the continuously changing analog signals such as temperature, flow, current, voltage, etc. into several digital signals that the CPU can process. The analog input circuit is generally composed of op amp conversion, mode conversion (A/D), photoelectric isolation, etc. Types of PLC input and output modules: digital input DI, digital output DO, analog input AI, analog output AO. Digital input and output are generally 24V. There are 4 kinds of analog quantities in 2 categories, and the 2 categories are voltage type and current type respectively. Voltage type has 0-10V and -10 to 10V. Current type mainly has 4-20MA,0-20MA. Then the module converts the analog quantity into A number between +32767 and -32768 through A/D conversion, and then implements the control. The function of the signal template is to convert various process i/o signals. The input signals are converted into digital quantities, which are easy for plc to identify, process and analyze. The output is converted into analog to various regulating mechanisms for execution, or the output is converted into a 2-bit do quantity to control some devices such as start, stop, on and off

A Digital I/O module is an electronic device used to process and control digital signals, including switching signals. They are commonly used in industrial automation, control systems and electronic equipment to achieve the acquisition, transmission and control of digital signals. The digital input/output module has an input channel and an output channel, which can connect external digital signals to the control system. Digital Input channels Digital input channels are used to receive external switching or digital signals. It is usually used to detect switch status, button press, sensor signals, etc. A digital input channel converts an external signal into a high or low level of voltage or current, which is then passed on to the control system. Digital Output channel Digital output channels are used to control external devices, such as relays, switches, etc. By changing the status of the output channel, you can control the switching status of external devices. Usually used to perform certain operations, such as switchgear, control valves, etc. Features and functions of the digital input/output module include Number of channels: Digital modules usually have multiple input channels and output channels and can be connected to multiple switches or devices. Electrical isolation: Some modules have an electrical isolation function that can isolate input and output signals, thereby improving the reliability and safety of the system. Communication interface: The module can be connected to other devices through different communication interfaces, such as Ethernet, RS-232, RS-485, etc. Programming: Digital modules can often be programmed to be configured to determine how to handle input signals and control output signals.
