Large Digit Process Displays

MODEL LDDP-2000 Large Digit Process Displays

The LDDP-2000 is a highly flexible microprocessor based large digit process display with a standard scaleable display range of - 9999 to + 99999. The display is programmable for a wide variety of industry standard inputs, from an infra red (IR) hand held programmer (Model LDDPH, see ordering information). Only one IR programmer is required to programme as many displays (individually) as is required in any application anywhere on a plant

The LDDP-2000 is suitable for any application where data needs to be viewed from a distance, from the murky environments of heavy processing industries to clean room Laboratory applications.

The LDDP-2000 is available in 4 standard digit sizes, which relate to the viewing distance required for the data being displayed -

Inch 2.3 4.0 7.0 14.0

Mm 58 102 178 357

Viewing Distance 65ft. / 20 mtrs. 130ft / 40 mtrs 220ft / 70 mtrs 455ft / 140 mtrs

Cat No. Model 2023 Model 2004 Model 2007 Model 2014

The display's are housed in rugged aluminium enclosures to IP55 / NEMA 12 protection and complete with the hardware for mounting. All wiring connections and input type selection are made via terminals and DIP switches on the rear of the enclosure.

The mounting options are:

• Panel (models 2.3" and 4" only)

• Wall, Suspension (all models)

Remote Hand Held IR Programmer - model LDDPH

This feature allows easy ON SITE programming of the display with an easy to use 6 button IR programmer. One programmer is all that is required to re-programme or re-scale the input type on a host of displays anywhere on the plant without major disruption to production.

NOTE :- The LDDPH is required for all 4 sizes of display.

SERIAL COMMUNICATIONS RS-232, RS-485
The LDDP-200 is programmable for use with Serial Communications RS-232 or RS-485, its is also programmable for communicating the data by Sending, Broadcasting or Receiving.

Each display is supplied with (two) sample programs for running on a PC. This allows a fast means of checking the operation of a display system.

Application-specific software can be developed by Eagle Controls at very reasonable cost.
