PLC reference packs 17 configurable IOs for Industry 4.0

November 16, 2018 // By Julien Happich
Maxim Integrated Products' Go-IO reference design packs 17 configurable IOs in a space one-half the size of a credit card, enabling productivity-enhancing self-diagnostic capabilities in automated factory subsystems.

Digital factories can dynamically adjust the manufacturing line on the fly based on new or changing requirements. With its numerous IOs, Go-IO pushes intelligence closer to the edge, enabling active monitoring and communication of equipment health and status information as well as higher throughput and productivity. The reference design contains a MAX14819 low-power, dual-channel, IO-Link master transceiver with sensor/actuator power-supply controllers, a MAX22192 8-channel octal digital input with isolated Serial Peripheral Interface (SPI), with wire break detection and accurate input current limiters, a MAX14912 8-channel digital output driver featuring 640mA high-side switches or push-pull configurable outputs, capable of 200kHz switching rates while providing proprietary fast, safe demagnetization inductive kickback protection, a MAXM22511 integrated 2.5kVRMS isolated power and digital isolated RS-485 transceiver module supporting 25Mbps data rates with ±35kV ESD protection, a MAX14483/MAX14130 6-channel, 3.75kVRMS galvanic low-power digital isolator and the MAXM15462 Himalaya uSLIC voltage regulator IC and power module for cooler, smaller and simpler industrial power supplies.

In total, that is 12 highly integrated ICs with 17 IOs supporting multiple digital IO configurations, a 4-channel IO-Link master to provide a universal IO interface to both analog and digital sensors, and a robust 25Mbps isolated RS-485 communications channel that provides a reliable, multi-drop data network for uploading time-sensitive health and status information into a local data lake or the cloud.

The Go-IO reference design enables decentralized control, shifting control and intelligence from one central command centre to each automated piece of equipment, enabling equipment to adapt on the fly to changes in product specifications or manufacturing needs.
