IRIV IO Controller - IR4.0 Industrial I/O Controller

The IRIV IO Controller is an industrial-grade device designed to make automation tasks a lot easier. Powered by the Raspberry Pi RP2350 microcontroller, it is faster, safer and more efficient than its older versions. This controller can be an I/O expander, data gatherer, network gateway, or automation controller. 

It has 11 isolated digital inputs, 4 isolated digital outputs, and 2 analogue inputs, including a USB-C port for programming and configuration and an RJ45 Ethernet port powered by the W5500 Ethernet controller, giving you many different options for a variety of industrial projects.

The metal casing with a fanless design is DIN rail mountable, providing easy installation. The IRIV IO Controller integrates easily with the IRIV PiControl. You can use IRIV PiControl as your main system controller while using IRIV IOC to gather your data or monitor your machinery and automation.
