  • This reference design can provide solutions to a number of applications including industrial IOT, industry 4.0 and robotics, factory and process automation

Industrial IoT represents a variety of IoT applications, smart product design principles, and data-driven automation practices in the industrial sector of the economy. It widely utilizes modern sensor technology. This technology enhances different types of equipment with remote monitoring and maintenance capabilities.

On a larger scale, the Industrial IoT is a key element of Industry 4.0 or smart factory. It is a trend of automation that brings together modern cloud computing, IIoT, and AI. It is used to create intelligent and self-optimizing industrial equipment and facilities.

Rapid prototyping board

Maxim has released a reference diagram of its industrial IOT rapid prototyping board. The Go-IO is an Industrial-Internet-of-Things (IIoT) reference design. It is designed for rapid prototyping and development of configurable industrial-control systems. The typical end applications of the board include Industry 4.0 driven process automation for building automation for intelligent buildings, smart sensors, reconfigurable industrial control systems, and robotics.

Uses a modular approach

All these industrial applications require high performance, robust and configurable solution for automating industries. Go-IO provides this solution using a modular approach. These systems are enabled by highly integrated ICs from Maxim Integrated. These ICs deliver new levels of performance to the device. Additionally, it features lower power dissipation in tiny footprints.

Current dissipation of up to 1.2 A

Go-IO has four different boards. These different configurations provide a varying mix of type of I/O channels and communication interfaces. Using this, it can target different end-user applications. It provides an isolated digital output for up to eight channels. Out of these, four isolated channels can provide a continuous current dissipation of up to 1.2A. It also provides extra safety with safe/fast demagnetisation diagnostics.

Delivers low power and efficient signal processing

The 4-Port IO-Link Master version 1.1 is compliant with the TMG’s IO-Link Master Stack. It provides one isolated power and RS-485 COM port. It is a full-duplex port that can provide a data rate of up to 25Mbps.

The MAX32630 features an Arm Cortex-M4 with FPU CPU. It can deliver low power and high-efficiency signal processing functionality. It also reduces power consumption and increased ease of use. It supports multiple communication protocols such as SPI, UART, I2C and 1-Wire master. The USB interfaces are made using industry-standard FTDI USB chips.

Uses a digital galvanic isolator

Go-IO uses two different domains. These domains are separated using the Maxim digital isolator products. The field domain uses the 24V input supply and 24V GND for reference. The logic domain uses APP_PWR and APP_GND for reference. It is found on the application processor card.

The design also incorporates the MAX14483. It is a six-channel digital galvanic isolator. It features an RMS voltage of 3.75kV. It runs on Maxim’s process technology. The six signal channels are individually optimized for SPI applications. These channels also include very low propagation delay on the SDI, SDO, and SCLK channels.

Applications

In terms of applications, this reference design can provide solutions to a number of applications including industrial IOT, industry 4.0 and robotics, factory and process automation, IO-Link sensors and actuators and building automation.
