New Programmable Large Digital Display for Analog Inputs Offers High Visibility for Challenging Industrial Applications

YORK, PA-May 8, 2007-Presenting important process data to the plant production floor is now easily accomplished with the introduction of a new line of large digital displays. Red Lion Controls, Inc. announces the new programmable LDA, Large Digital Display for Analog Inputs. The LDA is a versatile 5 digit display available in 2.25 inch and 4 inch high red LED digits, with readability up to 130 feet and 180 feet, respectively. The LDA is available as a volt, current, or process meter with scaling, RS232/RS485 serial communications, and dual Form C relay outputs. The LDA also offers lightweight aluminum NEMA 4X case construction and adjustable display intensities.

"The LDA offers a reliable, highly visible 5 digit display, making it an ideal solution for reading flow rates, pressure or temperature measurements, or other challenging production floor applications," said Jeff Thornton, product manager, Red Lion panel meters and displays. "Programming the LDA is made simple with our easy-to-follow push-button menu or by using Red Lion's free robust Crimson Programming Software. Also, the LDA is capable of accepting current, process, or voltage signal, scaling them to the desired readout and transmitting the results on the large, easy-to-read display."

The LDA offers dual 5 Amp relays for control capability and two serial communication methods to relay the displayed information to a management system. RS232 communication allows the LDA to communicate with a control console up to 50 feet away, while RS485 communication allows the connection of up to 32 devices on a single pair of wires over distances of up to 4,000 feet. Once connected, the LDA adjusts to a wide variety of industrial applications by allowing users to set numerous scaling parameters through various programming options. The LDA Programming Menu is organized into six separate modules, grouped together by parameters related in function. Also, the LDA's nonvolatile E²PROM memory retains all programming parameters and count values once power is removed, securing information in case of an electrical outage.
