3. Product Features
- 16-Channel Relay Output: Equipped with 16 independent relay output channels, supporting single-pole and double-pole output configurations to meet diverse control requirements.
- On-Board Self-Diagnosis Function: The module can monitor and inspect its own operational status and the communication status of the peripheral bus in real time, ensuring stable system operation.
- No Configuration Required: Plug-and-play design without any parameter setting or software configuration, simplifying deployment and commissioning work.
- Clear Status Indication: The front panel is equipped with three LED indicators, including ST (operating status), PST (power status), and CO (control output), enabling intuitive status observation.
- Dual Power Return Design: The two sets of output groups can be connected to different process voltage sources, improving system flexibility and operational reliability.
