RP2350-Relay-6CH - industrial 6-channel module with relays and RP2350 microcontroller

Description

Industrial 6-Channel RP2350 Relay is a high-quality industrial relay module based on the Raspberry Pi RP2350B microcontroller, designed for reliability, safety, and easy integration into automation systems. The device features a dual-core, dual-architecture design, allowing operation in ARM Cortex-M33 or Hazard3 RISC-V mode, providing developers with flexibility and programming freedom. The module includes six high-quality relays rated up to 10A at 250VAC / 30VDC, enabling direct control of 230V AC mains devices or low-voltage circuits. Built-in galvanic isolation circuits — including signal opto-isolation and power separation — ensure safe and stable operation even in demanding industrial environments. The module offers an isolated RS485 interface for Modbus RTU communication and a 40-pin Raspberry Pi Pico HAT-compatible connector, allowing easy expansion with additional modules (RTC, CAN, RS232, LoRa, sensors, etc.).

Power is supplied via screw terminals supporting voltages from 7V to 36V DC, allowing direct use in industrial environments. Additionally, the board includes a USB Type-C connector for communication, power, and programming via drag-and-drop. Built-in LED indicators — for power, RS485 transmission (TX/RX), and a configurable RGB LED — provide real-time system status monitoring. The robust ABS enclosure with DIN rail mounting ensures ease of installation and operational safety. The module supports programming in C/C++, MicroPython, and Arduino IDE, and provides a comprehensive SDK, documentation, and examples to streamline development. With its extensive protection features, industrial-grade performance, and reliable operation, the RP2350 Relay Module is ideal for building automation, device control, and IoT projects requiring high safety standards.
