Ultra-Portable IO on the Go MEET Go-IO Smart factories (often referred to as Industry 4.0) are made possible through the convergence of industrial IoT, adaptive manufacturing, cloud computing, and artificial intelligence. 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 ROBUST schedule a technician to reconfigure equipment. DIGITAL IO COMMUNICATIONS Increasingly, this new level of intelligence is MAX14912 Octal Digital Output with MAXM22511 Integrated Iso Power Fast / Safe Demag with Diagnostics with Iso RS485 Transceiver being moved to the very edge of the factory MAX14483 / MAX14130 Low Power, MAX22192 Octal Isolated Digital Input Small Size, Digital Isolators floor. The MAXREFDES212 Go-IO programmable IO-LINK INDUSTRIAL POWER logic controller (PLC) reference design (Figure MAX14819 Dual IO-Link Master MAXM15462 42V, 300mA Himalaya TM Transceivers, with Integrated 1) consists of multiple software configurable IOs uSLIC Step-Down Power Module Framer and L+ Supply Controllers in a compact form factor (less than 1 cubic inch) to address the needs of industrial automation, building automation, and industrial robotics.
