When industrial IoT, adaptive manufacturing, cloud computing, and artificial intelligence come together, you get the industrial convergence that truly brings to life the smart factory, also known as Industry 4.0. The promise of industrial convergence is increased productivity as well as the agility needed to adapt the manufacturing line for multiple products without having to stop production or schedule a technician to reconfigure equipment.

Companies are increasingly seeking to move intelligence to the edge of the factory floor. The Go-IO PLC reference design can help them achieve this, providing multiple software-defined I/Os in an ultra-compact (less than 1 cubic inch) industrial IoT solution. This allows an unparalleled level of integration to address the needs of industrial automation, building automation, and industrial robotics applications. Go-IO continues Maxim’s strong commitment to empowering design innovation by providing the technologies that engineers need to quickly create and prototype new industrial control systems.

Key features

The Go-IO reference design (MAXREFDES212) is a next-generation industrial IO solution that increases productivity, furthers adaptive manufacturing, and provides machine-level health and status information for making critical, real-time decisions.
  • Small Footprint
    With its ultra-small size (< 1 cubic inch: 1.7in.W x 1.56in.D x 0.25in.H), Go-IO can be integrated throughout the factory floor
  • Robust and Safe
    The Go-IO features advanced industrial products rated to withstand -40°C to +125°C, and includes our robust, safe, fast de-mag technology
  • High Efficiency
    Its modest energy signature increases efficiency, and you won’t need a cooling fan 
  • Packs a Powerful Punch
    Its 17 configurable IOs can control an entire manufacturing node or piece of equipment, including isolated digital inputs, digital outputs, IO-Link masters, and isolated RS-485 with integrated power
  • Extended Battery Life
    Go-IO is the first compact, portable PLC platform that can operate for a minimum of 8 hours using "AAA" batteries or a minimum of 12 hours from LiFePO4 rechargeable batteries
  • Programmable
    Programmable via the MAX32630 using the low-power Arm® Micro toolchain with Windows or Mac OS
  • Products featured in the Go-IO PLC Reference DesignIntelligence and Decentralized Control
    Enables automation equipment to act autonomously based on changing environments—as issues are identified, equipment can reprogram itself to perform another task 
  • Productivity and Throughput Increases
    Quickly isolates problems to facilitate higher factory uptime​
