Together, these four elements increase productivity by providing the flexibility to adapt manufacturing lines. This allows the production of multiple products without the need to stop production or schedule a technician to reconfigure equipment. Increasingly, this new level of intelligence is being moved to the very edge of the factory floor. The **MAXREFDES212** Go-IO programmable logic controller (PLC) reference design (Figure 1) consists of multiple software configurable IOs in a compact form factor (less than 1 cubic inch) to address the needs of industrial automation, building automation, and industrial robotics. GoIO provides design engineers with the means to rapidly create and prototype new industrial control systems before they are sourced and constructed. ## **ISOLATED DIGITAL INPUT** The **MAX22192** octal isolated digital input (Figure 2) translates eight, 24V, current-sinking industrial inputs to an isolated, SPI-compatible output. **==> picture [327 x 148] intentionally omitted <==** **----- Start of picture text -----**
