Product Description
Industrial 6-Channel RP2350 Relay Module for programmable switching and connecting RS485 devices. The RP2350-Relay-6CH is the standard version, combining an RP2350B microcontroller with six relays in a rail-mount ABS enclosure. It is intended for developers integrating load switching and industrial sensors or modules into custom control applications.
Connections use screw terminals, USB or the Pico HAT header. Power can be supplied through the DC input or USB. Power supply, optocoupler and digital isolation separate the corresponding circuit sections.
Highlights
- Dual-core RP2350B with a choice of Arm Cortex-M33 or Hazard3 RISC-V processors.
- 520 KB SRAM and 16 MB onboard Flash memory.
- Six relays with contact ratings up to 10 A at 250 V AC or 30 V DC.
- Isolated RS485 interface for connecting Modbus modules and sensors.
- Optocoupler, digital and power supply isolation for separating external circuits.
Technical Features
- Microcontroller: RP2350B, dual-core Arm Cortex-M33 or Hazard3 RISC-V, up to 150 MHz.
- Memory: 520 KB SRAM and 16 MB Flash.
- Relays: 6 channels, each with 1 normally open and 1 normally closed contact; maximum 10 A at 250 V AC or 30 V DC.
- Interfaces: isolated RS485, USB 1.1 with device and host support, 2 × I2C, 2 × UART and 1 × HSTX.
- Expansion connector: 40-pin header for compatible Raspberry Pi Pico HATs.
- Signal resources: 34 multifunction GPIOs, 8 ADC channels with 12-bit resolution and 24 PWM channels.
- Power supply: 7 to 36 V DC through screw terminals or 5 V through USB-C.
- Enclosure: rail-mount ABS case; dimensions 145 × 90 × 40 mm.
- Wi-Fi/Bluetooth module: no.
- Programming environments: C/C++, MicroPython and Arduino IDE.
Application Areas
- Switching AC or DC loads within the relay contact ratings.
- Integrating RS485 Modbus sensors into programmable switching applications.
- Expanding a rail-mounted controller with compatible Pico HAT functions such as RTC or CAN.
Notes
- The 40-pin header is compatible with only some Raspberry Pi Pico HATs.
- The onboard 120-ohm RS485 termination resistor is disconnected by default and enabled using a jumper.
