Industrial RS-485/Modbus Raspberry Pi HAT works with OpenPLC, supports 7V-32V DC input

Industrial RS485 Modbus HAT for Raspberry Pi

We have previously written about various industrial Raspberry Pi systems and gateways that come with RS-485 built in, but we had yet to cover a dedicated RS-485 Raspberry Pi HAT. To fill this gap, EngineElectronicAccessories, a developer based in Sweden, has introduced the “Industrial RS485 / Modbus HAT” designed for industrial automation, monitoring, and the OpenPLC open-source PLC suite. The board features an onboard RS-485 transceiver with TVS diode protection and supports long-distance communication over the RS-485 standard. It uses the Pi’s hardware UART interface and includes Tx/Rx LEDs for diagnostics. The board also accepts 7V to 32V DC input, so you can power both the HAT and the Raspberry Pi directly from a standard 24V rail, eliminating the need for a separate USB power supply in a control cabinet. Industrial RS-485/ Modbus HAT specifications: Compatibility – All Raspberry Pi boards with 40-pin GPIO header (Pi 3, Pi 4, Pi […]
