Wiring Diagram
The 6es7 138 4ca01 0aa0 module can be wired using a variety of methods, depending on the application. The following diagram shows the basic wiring for the module:
As shown in the diagram, the module has 24 digital inputs on the left side and 16 digital outputs on the right side. The digital inputs are labeled I0.0 to I0.23, while the digital outputs are labeled Q0.0 to Q0.15. The module also has a power supply input, which is labeled 24V DC.
Digital Inputs
The 24 digital inputs on the 6es7 138 4ca01 0aa0 module can be wired in two different ways: sinking and sourcing. In sinking mode, the common terminal of the input is connected to the negative terminal of the power supply, while in sourcing mode, the common terminal is connected to the positive terminal. The following diagram shows the wiring for sinking and sourcing modes:
As shown in the diagram, the digital inputs are connected to the common terminal and the power supply through a switch or sensor. The switch or sensor is connected between the input terminal and the common terminal. In sinking mode, the switch or sensor is connected between the input terminal and the negative terminal of the power supply, while in sourcing mode, it is connected between the input terminal and the positive terminal of the power supply.
Digital Outputs
The 16 digital outputs on the 6es7 138 4ca01 0aa0 module are wired in the same way as the digital inputs, but with the load connected between the output terminal and the power supply. The following diagram shows the wiring for the digital outputs:
As shown in the diagram, the digital outputs are connected to the power supply and the load through a switch or relay. The switch or relay is connected between the output terminal and the load. The load is connected between the output terminal and the power supply. When the output is activated, the switch or relay closes, and the load is connected to the power supply.
Power Supply
The 6es7 138 4ca01 0aa0 module requires a 24 V DC power supply. The power supply can be connected to the module through a power supply module, which is designed to distribute power to multiple modules. The following diagram shows the wiring for the power supply:
As shown in the diagram, the power supply is connected to the power supply module, which is then connected to the 6es7 138 4ca01 0aa0 module. The power supply module has a current rating, which must be sufficient to power all the modules connected to it.
