SNAP PAC System

Opto 22 SNAP PAC System is an integrated system of hardware and software for industrial control, remote monitoring, data acquisition, and the Internet of Things (IoT) applications. This system is designed to simplify the generally complex process of setting up an automation system. The SNAP PAC system consists of three integrated components: PAC Project™ Software Suite, SNAP PAC controllers, and SNAP I/O™ analog, digital, and serial I/O modules for connecting to field devices, machines, and sensors. These three simple and flexible components form a system that can handle any application, from basic equipment monitoring to complete factory automation. The Opto 22 controllers include rack-mounted, standalone, and software-based PACs to meet a variety of automation needs.
