Function

Bidirectional digital signal interaction: Integrating 16 input and 16 output channels, it can simultaneously achieve the collection of digital signals in industrial sites and the drive control of loads, without the need for separate configuration of input/output modules, saving cabinet space and costs.

High stability signal processing: The input channel is equipped with polarity protection and filtering functions. The input filtering time can be adjusted through software to effectively suppress electromagnetic interference in industrial sites and prevent false signal triggering. The output adopts a transistor structure with a fast response speed (microsecond delay), making it suitable for high-frequency switching control scenarios.

Flexible load adaptation: With an output current of 0.5A per channel, it can directly drive commonly used small industrial loads without the need for additional intermediate relays, simplifying wiring and system structure. The design with a total output current of 16A meets the load requirements of multiple channels working simultaneously.

Seamless integration with Siemens ecosystem: No additional driver required, plug and play. Parameters such as input filtering and output status diagnosis can be quickly configured through STEP 7 software. It works in coordination with S7-300 series PLCS and other expansion modules, with strong compatibility.

Intuitive status and 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 detection.
