Programmable logic controllers enable industrial IoT applications
Mouser now stocks the Opta micro PLC from Arduino. The easy-to-use controller permits designers to scale industrial automation projects utilising the open Arduino ecosystem. The PLC supports real-time control, monitoring, and predictive maintenance, making it an excellent option for IoT and building automation applications.
The PLC is based on the STM32H747XI dual-core microcontroller from STMicroelectronics, which incorporates a single high-performance Arm Cortex-M7 core running up to 480MHz and a lower-power Cortex-M4 core running up to 240MHz alongside a shared FPU.
The device is offered in three variants, including the Opta Lite, which includes Ethernet connectivity and USB Type-C for programming; the Opta RS485, which adds RS485 half-duplex support; and the Opta WiFi, which includes radios for Wi-Fi and BLE connectivity.
All models support OTA updates and provide a dedicated secure element for cryptographic assurances and relays for switching four loads up to 2.3kW each. The highly versatile controllers also incorporate optional support for standard IEC 61131-3 PLC languages and fieldbus integration via Modbus TCP and Modbus RTU.
The PLCs were recently featured in a Mouser Webinar, providing device designers with everything they need to know to develop and scale their industrial automation projects.
