Here are some key features of the module:

Digital Inputs: It provides 4 digital input channels. These inputs can be used to monitor the status of external signals, such as switches, sensors, or other devices.

Digital Outputs: It also offers 4 digital output channels. These outputs can be used to control external devices, such as actuators, solenoids, or indicators.

Voltage Range: The module supports a wide range of input and output voltage levels. The input voltage range is 24V DC, and the output voltage range is also 24V DC.

Type of Inputs/Outputs: The module supports both sinking and sourcing type inputs and outputs.

Connection: It can be connected to the S7-1200 PLC via a digital I/O module slot on the PLC's rack. It uses a module bus to communicate with the PLC.

Addressing: Each input and output point on the module is assigned a specific address within the PLC's memory, allowing you to access and manipulate the data associated with these points in your PLC program.
