Function

Bidirectional signal integrated processing: It integrates 8 input channels and 8 output channels, capable of simultaneously completing digital signal acquisition and load drive control in industrial sites. There is no need to split and configure separate input/output modules, simplifying the system architecture.

Anti-interference and signal protection: The input channel is equipped with polarity protection and software-adjustable filtering functions, which can effectively suppress electromagnetic interference (EMI) and signal jitter in industrial sites and prevent false triggering. The output channel adopts a transistor structure, featuring a fast response speed and is suitable for high-frequency switching control scenarios.

Flexible load drive: With an output current of 0.5A per channel, it can directly drive a small 24V DC load without the need for additional intermediate relays, reducing system costs. The design with a total output current of 8A meets the load requirements of multiple channels working simultaneously.

Seamless integration and rapid configuration: No additional driver required, plug and play. Parameters such as input filtering time and output status diagnosis can be quickly configured through STEP 7 software. It has strong synergy and excellent compatibility with S7-300 series PLCS and other expansion modules.

Intuitive fault diagnosis: The module is equipped with LED indicator lights for power supply (PWR), operation (RUN), and channel status, which can display the power supply status, working status, and the on-off status of each input/output channel of the module in real time, facilitating rapid on-site fault location.
