Function

Multi-type load compatible drive: The relay output is designed without polarity, which can directly drive both AC and DC types of loads, covering commonly used industrial devices such as 24V DC solenoid valves, 220V AC contactor coils, indicator lights, and other medium and low power equipment. There is no need to distinguish the polarity of the load power supply, reducing the risk of incorrect wiring.

Stable and reliable switch control: Each channel has an output current of 2A, which meets the requirements of most conventional loads. The mechanical and electrical life of the relay contacts is long, making it suitable for medium and low frequency switch scenarios. There is no temperature drift or aging problem of transistor output, and it has strong long-term operation stability.

Strong anti-interference and isolation protection: The electrical isolation design between the output channel and the backplane bus can effectively resist electromagnetic interference (EMI), surge voltage and ground loop interference in industrial sites, protect the PLC host and modules, and enhance the overall reliability of the system.

Seamless integration and rapid configuration: No additional drivers are required. Plug and play. The output channel status and fault diagnosis parameters can be quickly configured through STEP 7 software. It has excellent coordination and strong 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 on-off status of each output channel of the module in real time, facilitating rapid on-site troubleshooting.
