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 aluminium NEMA 4X/IP65 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, the Red Lion product manager for panel meters and displays: "Programming the LDA is made simple with our easy-to-follow push-button menu or by using the Red Lion 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 4000 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 organised into six separate modules, grouped together by parameters related in function.
Also, the LDA has a nonvolatile E2PROM memory, which retains all programming parameters and count values once power is removed, securing information in case of an electrical outage.
