WaveShare Industrial 6-Channel RP2350 Relay Module 2 in 1 accessory

SKU CH-3BVP-64YQV

Controls six relays via RP2350 dual-core MCU with isolated RS485, 40PIN Pico HAT header and 7-36 V optocoupler protection

  • Dual-core RP2350 runs up to 150 MHz for demanding industrial tasks
  • 520 KB SRAM plus 16 MB Flash stores firmware and data locally
  • Isolated RS485 interface connects Modbus devices without ground-loop interference
  • 40-pin Pico HAT header adds sensors, displays or extra I/O modules
  • Wide 7–36 V input with optocoupler and digital isolation protects circuitry

Industrial Relay Module for Embedded Control

The WaveShare Industrial 6-Channel RP2350 Relay Module is a 2 in 1 accessory built around the RP2350B microcontroller designed by Raspberry Pi. It targets engineers and developers who need deterministic switching of up to six loads in factory or test environments. The board combines relay outputs with a programmable dual-core processor so logic and actuation share one enclosure.

Rail-Mount Case with Isolated Interfaces

A DIN-rail compatible case lets the unit sit inside standard cabinets without extra brackets. Onboard optocoupler and digital isolation protect the RP2350B from high-voltage transients on the RS485 bus and field wiring. A 40PIN header accepts Raspberry Pi Pico HATs for sensor or display expansion while the USB Type-C port handles power and firmware uploads.

Six Relay Channels Driven by Dual-Core RP2350B

The deciding specification is the six independently controlled relay channels managed by a 150 MHz dual-core RP2350B with 520KB SRAM and 16MB Flash. Buyers who need more than six switched circuits or who require a different fieldbus such as CAN or Ethernet will need additional hardware.

Questions about this item

What does the isolated RS485 interface support for industrial Modbus modules?

The onboard isolated RS485 interface connects directly to Modbus industrial modules and provides optocoupler isolation to protect against high-voltage interference on the bus.

What physical mounting option does the rail-mount case provide?

The industrial-grade rail-mount case is designed for standard DIN-rail installation inside control cabinets or enclosures.

How is the module powered and programmed through the USB Type-C connector?

Connect 7-36V to the power terminals for operation, then use the USB Type-C port for data transfer and firmware programming without an extra power source.
