Industrial 8 Channel Modbus RTU Ethernet Relay Module (D) - Digital Input and RS485 Interface

Industrial 8 Channel Modbus RTU Ethernet Relay Module (D) - Digital Input and RS485 Interface

Industrial 8 Channel Modbus RTU Ethernet Relay Module (D) - Digital Input and RS485 Interface is an industrial 8 channel relay module controlled via RS485 bus with 8 channels of digital input using the Modbus RTU protocol. It has built-in protection circuits such as power isolation, magnetic isolation and TVS diode. It also comes with an ABS housing. The Modbus RTU Relay (D) is very easy to use. Due to its fast communication, stability, reliability and security, it is an ideal choice for industrial control equipment and/or applications with high communication requirements.

Features

• Configurable device address (1~255), multiple devices can be connected to RS485 bus
• SKU: 26517
• It has flash-on, flash-off function, relay can be opened for a while by passing argument to the command and then closed can be 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 the surge voltage and transient surge voltage in the circuit, provide over-current/over-voltage protection, lightning resistance and anti-electrostatic
• Built-in Optocoupler isolation, prevent the relay from being blocked by high voltage circuit
• Adopts special relay driver chip with built-in flyback diode protection for stronger and more stable driving ability
• Bidirectional optocoupler isolation, supports passive and active digital input with built-in debouncing algorithm. Relay supports digital input connection control or switching control
• Reverse-proof circuit prevents accidental damage to the circuit due to incorrect connection
• High-quality relay, contact rating: ≤10A 250VAC/30VDC
• Rail-mounted ABS plastic housing, easy to install, safe to use
• Multiple LEDs to indicate MCU status and signal transmission status
