Reference design outputs 4 analogue variables, cuts component count

May 13, 2014 // By Graham Prophet
Using one-third fewer components, this high-efficiency reference design from Maxim Integrated, the Alameda subsystem, is a flexible 4-channel bipolar analogue output module for industrial automation applications.

You can add a high-accuracy, 4-channel analogue output to an industrial automation designs with 33% fewer components than competitive designs, Maxim says; Industrial programmable logic controllers (PLCs) need multiple, flexible, high accuracy analogue outputs. The Alameda subsystem combines four high-accuracy (< ±0.1%) outputs with a high-efficiency, low-noise power supply controller on a single board. Alameda offers great flexibility—its outputs are configurable to ±10V, ±20 mA, 0 to 10V, or 4–20 mA for current and voltage applications. Automatic error reporting for detecting open and short circuits, brown-outs, and overtemperature conditions make this subsystem ideal for demanding, precision industrial control and automation applications.

The design...

- is fully tested: schematics, layout files, and firmware are available for immediate use and customization.

- uses fewer components: unique, integrated parts reduce number of components by 33% compared to competitive designs.

- speeds designs: integrates an efficient power supply with a 4-channel analogue output in a single compact system to solve noise issues and save engineers development time.

- improves PLC system reliability: automatically detects short-circuit, open-circuit, brown-out, and overtemperature conditions.
