Maxim Integrated Micro PLC platform

Using the Micro PLC platform from Maxim Integrated, designers now have the tools to implement Industry 4.0 with less power and fewer parts. The platform consists of five reference designs which can operate as stand-alone subsystems and be configured and tested with a laptop’s USB port.

The product is said to process up to 70 times faster digital I/O, providing increased production throughput. It has greater than 50% power savings, allowing fanless operations and higher density of I/Os.

The device reduces component count and provides diagnostics to help keep a line up and running 24/7. Its compact size, with a 10 times reduction in form factor, brings the full capability of a modular PLC closer to the factory floor. The platform will thus reduce industry maintenance costs and increase uptime.

Maxim has developed multiple products that are interoperable with the platform: MAX11270, a 24-bit, 10 mW, delta-sigma ADC with integrated PGA offering high signal-to-noise and low power; MAX17515, a 5 A, 2.4 to 5.5 V input, complete switchmode power supply with built-in inductor that reduces energy loss and heat with 92% efficiency; and MAX17552, a 4 to 60 V, 100 mA, ultrasmall, synchronous step-down DC-DC converter, compliant to IEC61131-2 PLC standard, which reduces heat dissipation and enables up to 50% cooler operation.
