Working Principle:

• Signal Acquisition and Access: The module is equipped with multiple input channels, supporting various types of signals such as analog signals (e.g., current, voltage signals), digital signals (e.g., switch signals), and frequency signals. It can connect to sensors for temperature, pressure, flow, etc., as well as various switching devices, accessing signals generated by on-site equipment into the module to prepare for subsequent processing.
• Signal Conversion: The module has a built-in signal processing circuit with signal conversion functions. It can convert the accessed analog signals into digital signals or perform the reverse conversion according to actual needs, facilitating signal transmission in the LIM link and recognition and processing by other devices. At the same time, it can amplify and filter signals to improve signal accuracy and stability and reduce interference.
• LIM Link Communication: The TK-IOLI01 supports the LIM link communication protocol. It encapsulates the processed signals according to the LIM link protocol and then transmits these signals to the LIM link network, enabling the signals to be transmitted to other related devices in the network, such as PLC controllers. Meanwhile, it can also receive signals from the LIM link, preparing for the next step of signal output.
• Control Signal Output: Based on the controller instructions received from the LIM link, the module outputs control signals to on-site equipment through its output channels. For example, it controls the start/stop of motors and the opening of valves, thereby achieving precise control of industrial equipment and completing various control tasks of the automated control system.
• Flexible Configuration and Adaptability: The module has flexible configuration options. Users can set I/O point types, signal ranges, communication parameters, etc., according to specific application scenarios and needs, enabling the module to better adapt to different industrial automation control systems and meet diversified control requirements.
• Fault Diagnosis and Protection: The module has a fault diagnosis function, which can monitor its own working status in real-time. When abnormal conditions such as overcurrent, overvoltage, or internal circuit faults are detected, it will promptly send out alarm signals and may take corresponding protection measures, such as cutting off part of the circuit, to ensure the safe operation of itself and the entire system.
