Description:
Waveshare Industrial Modbus RTU 8-ch Relay Module (B) is an industrial 8-ch relay module controlled via RS485 bus, utilizing Modbus RTU protocol. It features embedded protection circuits such as power isolation, magnetical isolation, and TVS diode, etc. Modbus RTU 8-ch Relay Module (B) also comes with an ABS enclosure. The Modbus RTU Relay (B) is very easy to use. Due to its fast communication, stability, reliability, and safety, Modbus RTU 8-ch Relay Module (B) is an ideal choice for industrial control equipment 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 magnetical 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, lightningproof & anti-electrostatic
- Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
- Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
- High quality relay, contact rating: ≤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
