Graphic Logic Controller
- LT Series Type H

Pro-face, a leader of Human Machine Interface (HMI) products, announces the addition of a new Graphic Logic Controller series, the LT Series. Three new models of the LT Type H Series were released in February 2003.

The LT Series combines display, operation and control functions into a single, easy-to-read, low-cost unit. The LT type H has 5.7-inch graphic touch panel display and comes with a variety of useful interfaces - 32-point digital I/O, analogue I/O, temperature input, high-speed counter input, PWM output, and pulse output.

For measurement control, the type H unit's analogue I/O interface allows you to convert numeric data to a line graph displayed on any screen. For fast and accurate positioning, the unit can be used for both high-speed counter based positioning, and pulse-motor based positioning. For temperature monitoring, the type H unit is equipped with Thermocouple K/J and Pt 100 features for monitoring and controlling temperature.

LT Editor software lets you easily write logic programs and create screens on a Windows based computer. The file management function is extremely convenient, and all basic operations are mouse controlled. A simple three-step process makes an application in minutes. Set up a logic program using 47 ladder instructions, create screens by choosing from 1,840 pre-made parts, and then link programs and screens by dragging and dropping the ladder instructions for each screen.

Using HMI and a separate PLC with an additional analogue or temperature input unit is high in cost, programming time, and space required. With LT type H these expensive, complex, large-sized production control systems are a thing of the past. The new LT type H is an ideal solution for a wide range of applications – food processing, packaging, textile, printing, semiconductor, and more!
