MAGNA Series Strain Gauge / Load Cell Input Large Digit Displays feature a signal conditioner for use with 0.5 mV / V to 4 mV / V load cells, an isolated excitation capable of powering up to four 350-ohm bridges in parallel at 10V and 120 mA, and easy scaling for display in engineering units such as lbs or kg. Standard feature include digital signal filtering with a time constant adjustable from 0 to 25 sec, selectable last-digit rounding of 1, 2, 5, 10, 20 and 50, and 10-point custom curve linearization.

Viewing distances up to 320 feet (100 m) are achieved with 8" 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 as standard: 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 or 6.

Indoor or outdoor viewing: MAGNA Series Displays with normal brightness LEDs can be read over a machine or across a plant floor. Displays with outdoor brightness LEDs can be read across an industrial yard, parking lot or roadway, for example to display vehicle load. A heater option allows outdoor operation in winter in cold climates. Available mounting options are panel mount, wall mount and suspension mount. Environmental sealing to IP65 (NEMA-4X) is standard.

Options available 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.
