Features

Configurable device address (1~255), multiple devices can be connected to RS485 bus
SKU: 17658
Has flash-on, flash-off function, by passing argument to command, the relay can be turned on for a while and then automatically turned off
Built-in one-piece power supply isolation, provides stable isolated voltage, no need for extra power supply for isolated terminal
Built-in one-piece magnetic isolation, enables signal isolation, high reliability, strong anti-interference, low power consumption
Built-in resettable fuse and TVS (Transient Voltage Suppressor) effectively suppress overvoltage and transient surge voltage in the circuit, provide overcurrent/overvoltage protection, lightning-proof and anti-electrostatic
Built-in Optocoupler isolation, prevents the relay from being interfered by high voltage circuit
Reverse protection circuit, prevents the circuit from being accidentally damaged by wrong connection
High-quality relay, contact rating: ≤10A 250VAC/30VDC
Rail-mounted ABS plastic housing, easy to install, safe to use
