Mini PLC range
18 June 2015
RS Components (RS) has extended its automation and control portfolio with ultra-compact mini PLCs that require no peripheral components for autonomous operation, thereby helping to simplify wiring and assembly.

The Barth Elektronik STG-500 and STG-600 mini PLCs provide 10 I/Os and 19 I/Os respectively, comprising digital, analogue and PWM channels. A temperature sensor is also built in. The STG-500 measures 40 x 40 x 22mm and has a universal aluminium mounting plate, while the STG-600 has an ultra-flat 10mm-high housing and maximum dimensions of 9 x 45 x 15mm.
Both models have very low current consumption and a wide operating voltage range of 7 to 32V, making them suitable for use in 12 or 24V battery-powered applications. Built-in protection for all I/Os, high shock and vibration resistance, and IP20 sealing, ensure reliability in harsh environments.
In addition, graphical programming capability makes the mini PLCs convenient and easy to use. The downloadable miCon-L software suite meets the standards of the latest graphical programming languages, and also integrates simulation and test capabilities. The flexible programming option offers a variety of possibilities in industrial, automotive and maritime applications.
Users can start building applications quickly by ordering the STA-500 or STA-600 starter kit, which includes the mini PLC and all necessary cables and manuals.
