Features
- Configurable device address (1~255), multiple devices can be connected to RS485 bus
- SKU: 24921
- With flash-on, flash-off function has, it is possible to open the relay for a while by passing argument to the command and then close it automatically
- Built-in single-body power supply isolation, provides stable isolated voltage, does not need extra power supply for isolated terminal
- Built-in single-body magnetic isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
- Built-in resettable fuse and TVS (Transient Voltage Suppressor) effectively suppress the surge voltage and transient surge voltage in the circuit, provide over-current/over-voltage protection, lightning-proof and anti-electrostatic
- Built-in Optocoupler isolation, prevent the relay from being blocked by high voltage circuit
- Built-in special relay driver chip, with built-in freewheeling diode protection, driving ability is stronger and more stable
- Reverse protection circuit, prevents the circuit from being accidentally damaged by wrong connection
- High-quality relay, contact rating: ≤10A 250VAC/30VDC
- ABS case with rail mounting, easy to install, safe to use
- 3 LEDs to indicate MCU status and signal transmission status
