The Magna Series Large Digit Display with a 8-inch (200 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:

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.

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.

Frequently Asked Questions About This Model

Is this the largest digit height MAGNA offers as a standard option?

Yes — 200 mm (7.9"/8") is the largest of the four standard digit heights in the MAGNA Series; larger custom digit heights of 12", 16", 24", or 32" are available by special quotation for applications needing even longer viewing distances.

What's the maximum viewing distance this model supports?

Using the 40x rule (viewing distance in feet is roughly 40 times digit height in inches), this 8-inch model supports viewing distances up to about 320 feet (100 meters), the longest range in the standard MAGNA lineup.

Is this model suitable for displaying kilowatt output at a power generation facility?

Yes — with a process signal input, it's used at power plants to show real-time energy output such as kilowatt output or voltage, with the large digit height ensuring the reading stays visible from a control room or across a facility.

Can this display show flow rate alerts for a water treatment plant?

Yes — it can display current flow rate in a water or sewage treatment application, and paired with the optional relay outputs and alarm hysteresis settings, it can also flag when flow rates fall outside acceptable thresholds.

Is the price difference between this 8-inch model and the 6-inch model significant?

Yes, generally — the largest digit height and case size in the standard lineup carries the highest price point among the four standard digit heights; the added cost is generally justified specifically when the required viewing distance exceeds what the 6-inch model (roughly 240 feet) can provide.

Can this model display both temperature and pressure readings from a critical system?

Not simultaneously on one unit — each display shows one configured signal at a time, so showing both temperature and pressure requires either two separate 8-inch units or a system that cycles between the two readings on one display.

Is this model appropriate for tracking elapsed time on a long industrial process?

Yes — with a clock/timer signal input, it can show elapsed time for specific tasks or processes, with the large digit height making it easy to check progress from anywhere on a large production floor.

Does the case size for this model create special installation considerations compared to smaller MAGNA displays?

Yes — at 200 mm digit height, the 4-digit case is 750 x 290 mm (29.5" x 11.4"), substantially larger than any of the shorter digit heights, so confirming adequate wall, panel, or suspension mounting space and structural support is more important than with the smaller models.

Can this display show machine status codes like run time or error codes?

Yes — it's used for exactly this in industrial manufacturing settings, showing operational status information including run time, downtime, and error codes, in ASCII or numeric display mode depending on the code format.

Is a custom digit height ever a better choice than this standard 8-inch model?

Only when the application genuinely needs a viewing distance beyond roughly 320 feet or a non-standard installation constraint; for anything within that range, the standard 8-inch model is the simpler and faster option to order compared to a custom quotation.

Questions From the Field

We're planning a mounting location for this display and aren't sure our wall or structure can support the case — what should we check?

At 750 x 290 mm for the 4-digit, 8-inch case, confirming the mounting surface or bracket is rated for the unit's weight and dimensions before installation is the standard first step, since this is significantly larger and heavier than the smaller MAGNA case sizes.

Our energy output display seems to lag behind actual generation changes — 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 reading but delays how quickly it reflects real changes in output.

Our flow rate alarm isn't triggering when the rate clearly falls outside our threshold — what should we check?

Reviewing the alarm's hysteresis and in-band/out-of-band function settings against the intended threshold is the standard first step, since a misconfigured alarm function can fail to trigger even when the underlying reading is clearly out of range.

We're comparing this 8-inch model to a 6-inch model for a yard application and aren't sure the extra size is worth it — how do we decide?

Measuring the actual distance from the display's planned location to where it needs to be read, then comparing that against the 6-inch model's roughly 240-foot range and this 8-inch model's roughly 320-foot range, is the standard way to confirm whether the larger, more expensive model is actually necessary.

Our machine status display is showing an error code we don't recognize — what should we check?

Confirming the display is configured for the correct mode (ASCII vs. numeric) to match how the source system encodes its status and error codes is the standard first check, since a mode mismatch can cause a valid code to display incorrectly or not make sense.

We need this display outdoors near sensitive equipment at a power facility — any special considerations?

Confirming the outside viewing brightness option and, if needed, the heater option for cold-climate operation were ordered, and verifying the NEMA-4 (IP65) sealing meets the facility's environmental requirements, are the standard checks before installing near sensitive utility equipment.

Our temperature and pressure readings need to be visible at the same time but we only have one display — what are our options?

Since a single unit shows one configured signal at a time, the standard options are ordering a second 8-inch display for the other reading, or using an upstream system to cycle between the two values on the one display if simultaneous viewing isn't strictly required.
