The Magna Series Large Digit Display with a 2-inch (57 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

What's the actual benefit of six digits over four at this same 2-1/4" digit height?

Since viewing distance depends only on digit height (both are rated to roughly 90 feet), the benefit of the 6-digit version isn't reading distance — it's digit capacity, letting the display show longer values like an HH:MM:SS clock, a 6-digit process reading, or a longer serial data string that wouldn't fit on the 4-digit case.

Can this model display a clock with hours, minutes, and seconds?

Yes — the clock/timer signal input option (MCT2) supports colon ":" separators between groups of two digits, which is exactly the format needed for an HH:MM:SS display; the 4-digit version can only show HH:MM without seconds.

How much wider is the 6-digit case compared to the 4-digit case at this digit height?

At 57 mm digit height, the 6-digit case is 376 x 155 mm compared to 280 x 155 mm for the 4-digit case — about 96 mm (3.8") wider, with the same height, which is worth confirming against available panel or wall space before ordering.

Is the 6-digit version meaningfully more expensive than the 4-digit version at this digit height?

Yes, generally — the added digits and wider case add cost over the equivalent 4-digit configuration; the price difference is worth weighing against whether the application genuinely needs more than four digits of resolution.

Can this display show a full serial data string from a PLC or PC?

Yes — with serial data input configured, the display can show any character within 7-segment display limitations in ASCII mode, and the extra two digits over the 4-digit version give more room for longer strings before truncation becomes a concern.

Does adding two more digits reduce the viewing distance compared to the 4-digit model?

No — viewing distance is governed by digit height, not digit count, so this 6-digit model has the same approximately 90-foot rated viewing distance as the 4-digit model at the same 57 mm digit height.

Is this model suitable for showing a quantity totalizer with decimal precision?

Yes — the Qa.Tot (quantity totalizer) display mode can accumulate weight or count values using a contact closure to trigger addition, and the extra digits give more room for larger accumulated totals than the 4-digit version can display.

What signal types can this 6-digit display accept?

The same full range as the rest of the MAGNA Series — serial data, process signal, strain gauge/load cell, temperature, pulse/frequency, and clock/timer — so choosing the 6-digit version doesn't limit which signal input type can be used.

Can this model be equipped for cold-weather outdoor use like the other MAGNA displays?

Yes — the heater option is available on this configuration the same as on every other MAGNA digit height and digit count, allowing outdoor operation down to -25°C (-13°F).

If I only need four digits now but might need six later, should I order the 6-digit version up front?

Since digit count is fixed at the time of manufacture and MAGNA units are non-cancelable/non-returnable, it's worth confirming the actual maximum value length the application will need to display before ordering, rather than assuming a 4-digit unit can later be swapped for six.

Questions From the Field

We're displaying a clock and the seconds field isn't showing — what should we check?

Confirming the clock/timer signal input was configured for the HH:MM:SS format (MCT2 with colon separators) rather than the HH:MM-only format is the standard first check, since ordering the wrong clock display mode is a common source of this specific issue.

Our serial data string is getting cut off on the display — why?

Since this 6-digit model can only display up to six characters within 7-segment display limitations at once, a string longer than six characters will be truncated or scroll depending on configuration; checking the actual string length being sent against the six-digit limit is the standard first step.

We ordered this expecting the same case width as our existing 4-digit unit and it doesn't fit our panel cutout — what happened?

At 57 mm digit height, the 6-digit case (376 x 155 mm) is noticeably wider than the 4-digit case (280 x 155 mm); confirming which digit count was ordered against the panel cutout dimensions is the standard first check when a replacement or additional unit doesn't fit as expected.

Our quantity totalizer display seems to be maxing out and wrapping around — what should we check?

Confirming the accumulated total hasn't exceeded what six digits can display, and reviewing the reset/rollover behavior configured for the totalizer function, is the standard first step when a running total appears to wrap unexpectedly.

We need to know if our existing 4-digit unit can be swapped in the field for this 6-digit model — is that possible?

No — digit count and case size are fixed at the time of manufacture, so upgrading from a 4-digit to a 6-digit display requires ordering a new unit rather than modifying the existing one in the field.

Our process reading looks like it's missing a decimal point compared to what we expected — what should we check?

Confirming the period/color divider configuration between digits matches the intended decimal placement for the process reading is the standard first check, since divider position is a configuration setting rather than something automatically inferred from the signal.

This display is reading correctly up close but the readout seems to wash out from across our facility — is this expected at this digit height?

Yes — at roughly 90 feet rated viewing distance for the 57 mm digit height, readability at greater distances is expected to degrade regardless of digit count; if longer-range visibility is needed, a 4" or larger digit height would be the appropriate upgrade rather than troubleshooting this unit.

Our unit's data logging output seems to lag behind real sensor changes — what should we check?

Checking the digital filtering time constant (adjustable from 0 to 25 seconds) is the standard first step, since a longer filter setting smooths the displayed and logged reading but also delays how quickly it reflects real changes in the source signal.
