The Magna Series Large Digit Display with a 6-inch (150 mm) 6-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:

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

Frequently Asked Questions About This Model

Can this display track multiple production metrics like target vs. actual output at once?

Not on a single unit — each MAGNA display shows one configured value at a time, so showing both a daily target and actual output simultaneously requires either two separate displays or a system that cycles between the two values on one display.

Is this model suited to gas concentration or air quality monitoring in a chemical plant?

Yes — with a process signal input, it can display gas concentration, air quality, or pollution metrics for safety monitoring, and the 6-inch size ensures the reading stays legible from a safe distance in these environments.

Can this display show a countdown timer for a cycle operation on an assembly line?

Yes — the clock/timer signal input configuration supports this kind of use, showing cycle times or countdowns so operators get immediate feedback on timing and can catch anomalies as they happen.

Is the 6-digit format useful for showing pallet counts or order numbers in a warehouse?

Yes — six digits give enough room for larger order numbers, pallet counts, or stock levels than a 4-digit display could show without truncating, which matters in high-volume warehouse operations.

Can this model track equipment downtime automatically, or does it need manual input?

It displays whatever value is fed to it from a connected signal source; automatically tracking downtime requires an upstream system (PLC, timer relay, or similar) computing and sending that value to the display — the display itself doesn't independently calculate downtime.

How does this model compare in cost to the 6-inch, 4-digit version?

The 6-digit case is wider (820 x 247 mm vs. 580 x 247 mm for the 4-digit at the same 6-inch height), and the added digits contribute to a higher price; whether the extra cost is worthwhile depends on whether the application's values genuinely need more than four digits.

Is this display appropriate for showing efficiency percentages on a factory floor?

Yes — it's specifically used this way in production monitoring applications, showing daily production targets, actual output, and efficiency percentages at strategic points on the factory floor for workers and supervisors to reference without approaching a computer.

Can multiple 6-digit displays in the same facility show different metrics from the same PLC?

Yes — each display can be independently configured for a different signal input from the same or different sources, so multiple units around a facility can each show a different metric (production count, environmental reading, downtime) simultaneously.

Does this model support integration with a maintenance scheduling system?

Yes, indirectly — via serial or process signal input, it can display maintenance-related metrics like machine run time or a countdown to the next scheduled maintenance, provided the connected system sends that data to the display.

Is this model a good fit for public-facing displays outside of industrial settings?

Yes — the same combination of large digit height, brightness options, and NEMA-4 sealing that suits industrial yards also works for public display applications, though check local requirements if the installation is in a public right-of-way.

Questions From the Field

Our production count display resets to zero at odd times during a shift — what should we check?

Checking the logic input wired for Reset is the standard first step, since one of the three configurable logic inputs may be triggered unintentionally by a signal from the connected line equipment rather than by an operator's deliberate action.

Our gas concentration display seems slow to reflect a rapid change in readings — what should we check?

Checking the digital filtering time constant, adjustable from 0 to 25 seconds, is the standard first step; a longer filter setting smooths the displayed reading but delays how quickly it reflects a fast-changing gas concentration, which matters for safety-critical monitoring.

We have several of these units around the plant and one shows a noticeably different efficiency percentage than expected — what should we check?

Since each unit is individually configured, comparing that specific unit's scaling parameters (direct or theoretical scale and offset) against the others is the standard first step, rather than assuming all units received identical configuration.

Our warehouse order number display is getting cut off — what should we check?

Confirming the order or pallet numbers in use don't exceed six digits is the standard first check, since this model can only display up to six characters at once; numbers exceeding that will be truncated rather than automatically wrapping or scaling down.

Our downtime tracking display doesn't seem to be counting during an actual equipment stoppage — what should we check?

Since the display only shows whatever value the connected upstream system sends it, confirming the PLC or timer relay computing the downtime value is actually detecting the stoppage and updating its output is the standard first step before suspecting the display itself.

Our assembly line's cycle countdown display seems to jump or skip numbers — what should we check?

Confirming the clock/timer signal input configuration and the source timing reference are set up correctly for the intended countdown behavior is the standard first check, since a mismatched configuration between the source and the display's expected format can cause skipped or erratic values.

We're mounting this outdoors near a chemical processing area and want to confirm it'll hold up — what should we check?

Confirming the unit was ordered with NEMA-4 (IP65) sealing (standard on this model) and, if the location has corrosive or highly humid air, discussing enclosure material options with support before installation is worth doing, since standard sealing protects against dust and water but not all chemical exposure.
