Description

Oversize digits for long viewing distances. Grand Series large digit displays are your flexible solution when a display needs to be viewed over distances as long as 320 feet (100 m). A rule of thumb is that viewing distance in feet is 40 times the digit height in inches, or in metric terms, that viewing distance in meters is digit height in millimeters divided by 2.

Four digit heights are available:  57 mm (2.2"), 102 mm (4.0"), 144 mm (5.7"), and 200 mm (7.9"). Solid segments are used for normal brightness 2.2" and 4.0" digits. Individual 5 mm LEDs are used for larger digits and outdoor brightness versions.

Versions for indoor industrial environments. Depending on the selected digit size and mounting location, a Grand Series display with normal brightness LEDs can be read across an entire plant floor, keeping the workforce aware of important variables without having to leave their work areas to view a small computer screen or control panel. Sealed to IP65 (NEMA-4X), Grand Series Displays are complete functional units, with all the necessary signal conditioning, power supply and display circuitry. Just apply power (95-264 Vac or optionally 11-30 Vdc), connect your input signal, and display your reading. There is a choice of mounting options: panel mount, wall mount, pole mount, or suspension mount. 

Versions for outdoor locations. Grand Series Displays are available in outdoor versions complete with outdoor brightness LEDs and an IP65 (NEMA-4X) rated weather cowl. They can be read across an industrial yard, parking lot or roadway, for example to display vehicle load or the number of available parking spaces.

Signal options. Grand Series Displays are available with input circuitry for process signals (e.g., 4-20 mA), load cell / weight, rate / frequency, totalizing, clock, elapsed time, and serial data. For example, in a plant environment, a large-digit display can show process variable such as temperature or pressure, or throughput related parameters such as flow rate, line speed, number of units produced, or elapsed time. The display of temperature requires an external 4-20 mA transmitter or a Laureate DPM with a linearized 4-20 mA analog output. As an alternative to displaying sensor data, Grand Series Displays can display a number transmitted as serial data from a computer or PLC.

Output options are RS-232/422/485 serial data and dual 2A relays for alarm.

Programming is by means of a Remote Programmer, which provides three contact switches labeled MENU, SELECT and INCR. The Remote Programmer utilizes a cord, avoiding the need to climb a ladder to access the display.
