A programmable Logic Controller is an industrial process control computer which has been "ruggedized" and adapted to control the manufacturing process. Almost all manufacturing processes are modernized and automated by adapting this technology to stay ahead of competition.
PLCs and PACs are similar as they both perform the same essential functions. With modern technology, their differences are becoming more blurred. The most notable difference between PLCs and PACs is their programming interface. PACs are more intricate, using C or C++. PLCs on the other hand, are programmed using ladder logic. These programming differences create distinctions in the architecture and capability between the two computers.
The Model TR1 Tru-Trac™ linear measurement solution is a versatile option for tracking velocity, position, or distance over a wide variety of surfaces. An integrated encoder, measuring wheel, and spring-loaded torsion arm in one, compact unit, the Model TR1 is easy to install. The spring-loaded torsion arm offers adjustable torsion load, allowing the Model TR1 to be mounted in almost any orientation - even upside-down. The threaded shaft on the pivot axis is field reversible, providing mounting access from either side. With operating speeds up to 3000 feet per minute, a wide variety of configuration options - including multiple wheel material options - and a housing made from a durable, conductive composite material that minimizes static buildup, the Model TR1 Tru-Trac™ is the ideal solution for countless applications.
