MAXREFDES61# 16-Bit Four Micro PLC Card

Maxim's Micro PLC Technology demonstration puts the power of industry 4.0 in the palm of your hand

Image of Maxim Integrated's MAXREFDES61# Micro PLC CardIndustry 4.0 marks the fourth industrial revolution, characterized by distributed, intelligent control systems. Breaking from a past with large, centralized programmable-logic controllers, Industry 4.0 allows for highly configurable, highly modular factories, which accept an ever increasing number of sensor inputs, while operating at a higher output than ever before. The ultra-small PLC, or MicroPLC, lies at the heart of the Industry 4.0 factory, providing high performance with ultra-low power consumption in an ultra-small package. MAXREFDES61# is Maxim’s MicroPLC, quad-channel, analog input card.

Maxim's MAXREFDES61# features a 16-bit high-accuracy four-channel analog input with isolated power and data. Two of the input channels accept -10 V to 10 V signals and the other two inputs accept 4 mA to 20 mA signals. The MAXREFDES61# design integrates a dual low-noise low-distortion buffer (MAX9633); a 16-bit 4-channel multirange input ADC (MAX1301); two high-voltage 4–20 mA current protectors (MAX14626) for the current input channels; an ultra-high-precision 4.096 V voltage reference (MAX6126); 600 VRMS data isolation (MAX14850); a STM32F4 microcontroller; a FTDI USB-UART bridge; a high-efficiency DC-DC converter (MAX15062); and isolated/regulated +15 V, +5 V, and -3 V power rails (MAX17498C/MAX8719/MAX1659/MAX1735). The entire system typically operates at less than 500 mW and fits into a space roughly the size of a credit card. While targeted for the industrial, MicroPLC application, MAXREFDES61# may be used in any application that requires high-accuracy analog-to-digital conversion.

Key Advantages
  • Small form-factor: 10x reduction in footprint brings the full capability of a modular PLC closer to the factory floor
  • High integration: reduces component count, improves reliability, and provides diagnostics to help keep a line up and running 24/7/365
  • Faster throughput: 70x faster digital I/O provides increased production throughput
  • Power efficiency: >50% power savings, allowing fan-less operations and higher density of I/Os
