Sense and Switch Industrial-Level Loads with your Raspberry Pi®
With Opto 22's Digital I/O System for Raspberry Pi, you can switch real-world electrical loads like industrial motors and pumps, and sense circuits and status through industrial-grade sensors, with your Raspberry Pi's GPIO. The system uses the same field-tested, reliable Opto 22 G4 input/output (I/O) modules that have served automation applications worldwide for nearly 40 years. Just bring your Pi and its power supply, and you’re ready to begin.

Raspberry Pi 3 Model B
Built on the latest Broadcom 2837 ARMv8 64bit processor, the new generation Raspberry Pi 3 Model B is faster and more powerful than its predecessors. With built-in wireless and Bluetooth connectivity, it becomes the ideal IoT ready solution.

Raspberry Pi 2 Model B v1.2
The Raspberry Pi 2 has enhanced features that render it capable of running a full range of ARM GNU/Linux distributions in addition to Microsoft Windows 10 IoT Core. Offering excellent flexibility for learners, it is ideal for school projects and is fully compatible with Raspberry Pi 1 devices.

Digital I/O Carrier Board
The OPTO-P1-4OP is a Digital I/O carrier board for Raspberry Pi that lets users switch industrial-level electrical loads, far beyond the Pi's built-in 3.3VDC GPIO pins, and monitor and control electrical loads required for real-world devices like industrial motors, pumps and sensors.
