紧凑的小尺寸（<1立方英寸：1.7in.W x 1.56in.D x 0.25in.H）使Go-IO可以集成到整个工厂车间。
Advanced factory automation solutions, such as Industry 4.0, require increasing numbers of smart sensors, which are typically controlled using IO-Link® for the point-to-point serial communication between the sensor and controller (master). As a leading provider of IO-Link sensor transceiver and master transceiver ICs, Maxim also provides complete reference design solutions to help our customers improve their time to market. These proven designs cover all of the hardware and software requirements needed for compliance with the IO-Link standard. The complete reference design, including all of the ICs and external protection devices such as TVS diodes, is provided on a 30mm x 7.5mm printed circuit board (PCB).
Maxim Integrated and Technologie Management Gruppe Technologie und Engineering (TMG TE) collaborated in designing the MAXREFDES171 as a reference design that is compliant with the IO-Link version 1.1/1.0 standard. The MAXREFDES171 design consists of an industry-standard MAX22513 IO-Link device transceiver, a MAX32660 ultra-low-power 16-bit microcontroller utilizing the TMG TE IO-Link device stack, and a commercially available VL53L1 distance sensor.

8-Channel IO-Link Master
The MAXREFDES176# is a complete, IO-Link® 16-channel digital input hub reference design that consists of a MAX22515 IO-Link transceiver with integrated protection. It demonstrates an isolated digital input hub using the MAX22192 isolated octal digital input device daisy-chained with the MAX22190 octal digital input device to provide a total of 16 digital input channels.
Type 1 and Type 3 sensors are supported by default. Type 2 sensors can also be supported by modifying the resistor value that controls the value of the current sink within the devices. Built in an industrial form factor, the MAXREFDES176# uses an industry-standard M12 connector, allowing a 4-wire cable to be used. The digital input channels use industry-standard PCB terminal blocks.
In this design, an Atmel® ATSAM low-power microcontroller interfaces between the MAX22192 isolated digital input serializer and the MAX22515 IO-Link device transceiver. The MAX22515 features integrated surge protection for robust communication in a very small PCB area without requiring external protection components, such as TVS diodes. The MAX22515 is available in a tiny 20-bump WLP package, allowing the MAXREFDES176# to have a small footprint, though this is mostly determined by the size of the connectors. The design is reverse-polarity protected using the integrated active reverse-polarity protection of the MAX22515. The MAX22515 has two integrated LDO regulators (3.3V and 5.0V). The 3.3V LDO is used to generate the 3.3V supply for other circuitry, reducing the number of required external components and further saving space. The MAX22515 also features low on-resistance drivers (C/Q and DO/DI) to reduce power dissipation, allowing this reference design to consume minimal power with very low thermal dissipation.
This IO-Link device utilizes the Technologie Management Gruppe Technologie und Engineering (TMG TE) IO-Link device stack to communicate to any IO-Link version 1.1-compliant master. The board contains a male M12 connector for connecting to a compliant IO-Link master using a standard M12 cable. Connecting the MAXREFDES176# to a USB IO-link master, such as the MAXREFDES165#, with the associated software allows for easy evaluation.
Design files, firmware, and software are available on the Design Resources tab. The board is also available for purchase.

The MAXREFDES177# is a complete, IO-Link® universal analog input-output (IO) reference design that has a MAX22515 IO-Link transceiver with integrated protection. It demonstrates a fully software-configurable analog IO module using the MAX22000 industrial configurable analog IO device. The analog (field) side is fully isolated from the IO-Link side with the MAX14483 digital data isolator and an isolated power supply derived from the L+ (24V) supply from the IO-Link master connection.
The MAXREFDES177#, built in an industrial form factor, uses an industry-standard M12 connector with a 4-wire IO-Link cable. The analog (field) side uses a 4-way PCB terminal block. The complete reference design fits on a 61mm x 25mm printed circuit board (PCB).
The configurable modes include analog voltage input (±10V), analog current input (±20mA), analog voltage output (±10V), and analog current output (±20mA) across the AIO and GND terminals. The MAXREFES177# sets the linear range at 105% and full-scale range at 125% of the nominal range. The accuracy is as good as 0.1% over a ±50°C temperature variation. The other two terminals can be configured to measure temperature using a standard device such as a PT100 or PT1000 RTD. These terminals interface to the integrated Programmable Gain Amplifier (PGA) in the MAX22000 at inputs AI5 and AI6.
An Atmel® ATSAM low-power microcontroller interfaces between the MAX22000 industrial configurable analog IO device and MAX22515 IO-Link device transceiver. The MAX22515 features integrated surge protection for robust communication in a very small PCB area without requiring external protection components such as TVS diodes. The MAX22515 is available in a tiny 20-bump wafer-level package (WLP), allowing the MAXREFDES177# to have a small footprint. The design is reverse-polarity protected using the integrated active reverse-polarity protection of the MAX22515. The MAX22515 has two integrated LDO regulators (3.3V and 5V). The 3.3V LDO generates the 3.3V supply for other circuitry, reducing the number of required external components and saving space. The MAX22515 also features low on-resistance drivers (C/Q and DO/DI) to reduce power dissipation, allowing this reference design to consume minimal power with very low thermal dissipation.

Go-IO is an Industrial-Internet-of-Things (IIoT) reference design designed for rapid prototyping and development of configurable industrial-control systems. Typical end applications include Industry 4.0 driven process automation for building automation for intelligent buildings, smart sensors, reconfigurable industrial control systems, and robotics. All these industrial applications require a high performance, robust, configurable solution, which Go-IO provides using a modular approach. These systems are enabled by highly integrated ICs from Analog Devices, delivering new levels of performance while delivering lower power dissipation in tiny footprints.
Go-IO has four different boards. The different configurations provide a varying mix of type of I/O channels and communication interfaces to target different end applications.
