Features

• Configurable device address (1~255), multiple devices can be connected to RS485 bus
• SKU: 25140
• Has the function of flash-on, flash-off, turn on the relay for a while and then automatically turn off by command can be closed
• Onboard voltage regulator chip, support 7~36V wide voltage power supply
• Onboard one-piece power supply isolation, provide stable isolated voltage, no need extra power supply for isolated terminal
• Onboard one-piece magnetic isolation, provide signal isolation, high reliability, strong anti-interference, low power consumption
• Onboard 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
• Onboard Optocoupler isolation, prevent the relay from being blocked by high voltage circuit
• Onboard special relay driver chip, with built-in freewheeling diode protection, driving ability is stronger and more stable
• Reverse protection circuit, prevent the circuit from wrong connection
