MAGNA Series Frequency & Rate Input Large Digit Displays accept frequencies from 0 to 100 kHz. They accept the most common industrial pulse inputs, namely contact closures, NPN or PNP proximity sensors, 5V logic pulses, 24V PLC pulses, and quadrature encoders. The units are easily scaled to display frequency in Hz or rate in  engineering units such as feet/sec, gallons/minutes, liters/sec, etc. An isolated 24V excitation output is standard to power active sensors and encoders.

A quartz-crystal controlled timing reference provides excellent long-term stability. Scaling is digital for excellent precision. Scale factors can be non-whole numbers, such as 1.245.

Displayed values can be smoothed by averaging multiple readings over a preset time. The units accept extremely low input frequencies, such as production rate from an assembly line which only produces two items per hour.

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.

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.
