Industrial Relay Module 8-channel RS485 - Modbus RTU, 30A, DIN rail housing
Professional 8-channel relay module with RS485 interface, based on the Modbus RTU protocol. Thanks to its power supply isolation, overvoltage and overload protection and robust DIN rail-mounted ABS housing, it is ideal for industrial applications requiring reliable communication and high switching currents.
Key features:
- RS485 communication - Modbus RTU protocol support
- Configurable device address (1~255), multiple modules can be cascaded
- Short relay on/off function (flash-on/off) - automatic switch-off after time
- Wide power supply range: 7V~36V with built-in stabiliser
- Isolation of power supply and signals - protection and immunity against interference
- Built-in self-resetting fuse, TVS diode, opto-isolation
- Supports high currents: up to 30A (250V AC / 28V DC)
- Dedicated relay driver - with overvoltage protection diode
- ABS industrial housing - DIN rail mounting
- Three LEDs: power, TX transmission, RX reception
