The Magna Series Large Digit Display with a 4-inch (102 mm) 4-digit configuration is a rugged industrial display engineered for clear data visualization. Featuring solid-segment LEDs for indoor use or optional 5 mm LEDs for outdoor brightness, it supports inputs including RS232/RS485, 4-20 mA, 0-10V, and pulse (0-100 kHz), with a 24V excitation output, 10-point linearization, and digital filtering (0-25s). It includes two or four 2A relays and an analog output, operating on 95-264 Vac or 11-30 Vdc, with an IP65 (NEMA-4X) seal and a temperature range of -40°C to 70°C, plus a heater option. Ideal for production monitoring and process control, it offers customizable LED colors and flexible mounting options.
Viewing distances up to 320 ft (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 a 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, 6 or 8, depending on the display function.
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.
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:
- Serial data from PCs, PLCs, serial output transmitters, and smart sensors.
- Process input (e.g., 4-20 mA)
- Strain gauge / load cell input
