Product Features

• Easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment’s and/or applications with high communication requirements.
• Configurable device address (1-255), multi devices can cascaded on RS485 bus
• Features flash-on, flash-off function, it is possible to turn on the relay for a while and then close it automatically via the command
• Onboard voltage regulator chip, supports 7-36V wide voltage power supply
• Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
• Onboard unibody magnetically isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
• Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over­ voltage proof, lightning proof & anti-electrostatic
• Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
• Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable
• Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
• High quality relay, contact rating: 1QA 250VAC/30VDC Rail-mounted ABS case, easy to install, safe to use
• 3 LEDs for indicating the MCU status and signal transceiving status
