Digital input module is an interface device used to connect external mechanical contacts and electronic digital sensors, such as two-wire photoelectric switches and proximity switches. The main function of the module is to convert the external digital signal from the field into the internal signal level of the PLC (Programmable logic controller).

Digital input modules usually have RC filter circuits to prevent incorrect input signals due to input contact jitter or external interference pulses. In addition, the input current is generally milliamps.

In practical applications, digital input modules are widely used in industrial automation systems to realize digital signal transmission and data processing between devices. The WES532-150 can be connected to the CPU module through an expansion cable or expansion connector, with both soft and hard connection modes.

In short, the digital input module plays an important role in the industrial automation system, and is one of the key components to realize the digital signal transmission and data processing between devices. When selecting and using the digital input module, it is necessary to consider the interface type of the device, the input signal type, the working environment and other factors to ensure that the module can meet the needs of the system and provide stable and reliable signal transmission.
