MAGNA Series Large Digit Displays

Serial Input Displays • Meters Counters • Clocks • Timers

Standard Features

  • Choice of 2-1/4", 4", 6" or 8" digit heights
  • Choice of 4 or 6 digits with period or color dividers
  • Choice of normal or outside viewing brightness
  • Choice of signal inputs and functions
  • Choice of panel mount, wall mount or suspension mount
  • Choice of 95-264 Vac or 11-30 Vdc power
  • Sealed to NEMA-4 (IP65)
  • Only 3.0" (75 mm) deep
  • Programmable from front panel
  • Optional two or four 2A relay outputs, analog output, serial I/O

Viewing distances up to 320 feet (100 m) are achieved with oversize digits. A rule of thumb is that viewing distance in feet is 40 times 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 (2-1/4"), 102 mm (4.0"), 150 mm (5.9"), and 200 mm (7.9"). Solid segments are used for normal brightness 2.2" and 4.0" digits. Individual 5 mm LED pixels are used for larger digits and outdoor brightness versions. The number of digits can be 4, 6 or 8, depending on the display function.

Indoor or Outdoor Viewing: MAGNA Series Displays with normal brightness LEDs can be read across an entire plant floor to keep workers informed without leaving their work area. Displays with outdoor brightness LEDs can be read across an industrial yard, parking lot or roadway, for example to display vehicle load. Available mounting options are panel mount, wall mount and suspension mount. Environmental sealing to IP65 (NEMA-4X) is standard.

Choice of Signal Inputs: MAGNA Series Displays are available for different signal types, with can each be associated with 4 or 6 digits. Please click on the links below for detailed information by signal type:

Options include two or four 2A relays, an analog output, an RS232 or RS485 serial data output, and 95-264 Vac or 11-30 Vdc power.

Intuitive Setup is normally provided by means of built-in front panel switches, which can be locked. It is also possible to remotely wire four pushbuttons to the display.
