How can devices with current output be connected to the AI module of a PLC?

Devices with current output, such as sensors or transmitters, can be connected to the AI (Analog Input) module of a Programmable Logic Controller (PLC) using a variety of techniques. The AI module of a PLC is designed to interface with analog signals, which typically involve continuous voltage or current values. To connect a device with current output, the PLC's AI module can be configured to accept the specific current range. This can be done through programming or by adjusting the module's settings. The device can then be connected to the AI module using appropriate wiring, ensuring that the correct polarity and signal conditioning (such as signal amplification or filtering) is applied if necessary. Once connected, the PLC can process and analyze the analog signal data provided by the device, enabling various automation and control functions based on the measured current levels.
