II. Key Features

Fully Isolated Design: 16 independently isolated channels, strong anti-interference, good fault isolation, suitable for complex industrial environments.
Wide voltage compatibility: 10–30V DC, suitable for 12V/24V industrial loads.
High load capacity: Maximum 2A per channel, meeting the drive requirements of solenoid valves and high-power relays.
Status indication: Green LED on each channel indicates output status; red LED on the module indicates fault.
Flexible configuration: Output status can be configured via software in fault/programming modes.
No reverse polarity protection: Pay attention to polarity during wiring; reverse connection may damage the module.
