Overview:
This is an industrial 8-ch relay module controlled via RS485 bus, utilizing Modbus RTU protocol. It features embedded protection circuits such as power isolation, ADI magnetical isolation, and TVS diode, etc. It also comes with an ABS enclosure. The Modbus RTU Relay is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirement.
Features:
Configurable device address (1~255), multi devices can be cascaded on RS485 bus Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit,anti-electrostatic Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection High quality relay, contact rating: a???10A 250VAC/30VDC Rail-mounted ABS plastic enclosure, easy to install, safe to use 3 LEDs for indicating the MCU status and signal transceiving status
Specifications:
Power supply voltage: 5V Communication interface: RS485 Baudrate: 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000 Default communication format: 9600, N, 8, 1 Relay channels: 8 Contact form: 1NO 1NC Communication protocol: Standard Modbus RTU protocol RS485 address: 1~255 RS485 terminal protection: 600W?surge-suppress, 15KV ESD protection (reserved 120R balancing resistor solder pads)
LED indicators:
STA: MCU indicator, keep flashing when the MCU normally working TXD: TX indicator, light up when sending data RXD: RX indicator, light up when receiving data
Package included:
1 x Relay module?
