LED & LCD display boards

One number, read across the floor.

KVAR designs and manufactures its own LED and LCD display boards — production Andon, target/actual/gap, counters and takt; environment and process values; price and rate boards; tokens, clocks and public information. Driven straight from your PLC, sensor, Modbus or Profibus network, or from software — indoor or outdoor, in any digit size. Built in-house, so a board can be shaped to exactly what you need to show.

Standard board off the shelf, a custom board to your data and hall, or a networked, software-driven wall — every display is made to be seen and made to fit.

Displays for every job on site

One product family — the same rugged boards, the same interfaces — configured to show whatever the floor, counter or gate needs to read at a glance.

Why a KVAR display

▣

We build them

Designed and manufactured in-house — digit size, layout, colour, interface and enclosure are ours to shape, not a catalogue you have to fit into.

🔌

Any source

Reads a PLC, a sensor, a Modbus / Profibus network, an analog signal or software — no separate gateway, no fuss.

🌐

Indoor & outdoor

IP-rated outdoor cabinets, high-brightness modules for sunlight, viewing distances to 50 m and beyond.

⏱

Made to last

Industrial-grade LEDs, 30,000-hour rated life, metal enclosures — hung on a wall and forgotten, in the best way.

Display types

What we make

A range built from real installations — production floors, process plants, retail counters and public spaces.

Target / Actual / Gap production display — **Industrial / Andon**Target, actual and gap; production counters, takt, cycle time, downtime and status lamps. Driven from the PLC or the Production Genie / Andon software.

Environment display — dewpoint, humidity, temperature — **Environment & process**Temperature, humidity, dewpoint, AQI and pressure on a multi-parameter board — read over Modbus / RS485 from the sensor or logger.

Multi-parameter process display board — **Rate & retail**Price, gold, fuel and currency rate boards; multi-colour digits, large heights for the forecourt or the shop front.

Safety / information display board — **Information & safety**Days-since-incident, welcome and notice boards, transport and traffic, token / now-serving — alphanumeric, scrolling or fixed.

Digital clock display — **Time & score**Digital and GPS-synchronised clocks, count-up / count-down timers and scoreboards for plants and public spaces.

Programmable indicator / meter display — **Instrument & indicator**Large-digit ammeter / AH meters, programmable indicators and remote counters that repeat an instrument reading across the shed.

Public air-quality display board — **Air quality & public**Outdoor air-quality boards — CO₂, NO₂, PM2.5, PM10 and AQI — and parameter boards read straight from the sensor or logger.

Don’t see yours? Because we design and build the boards, a display can be made to show exactly your data, in your layout, colours and language, with the interface your equipment already speaks. Tell us what needs to be read and from how far — we’ll build the board for it.

In the field

Process-parameter display board installed in a plant — **Process-parameter board** — raw-material feed rate, stack temperature, fan-damper position, BTP and machine speed, read straight from the PLC; visible from the shop floor and the control room. Used in cement, steel, thermal-power, mineral-processing, sinter and chemical plants.

GPS digital clock in various applications — **GPS digital clock** — accurate, GPS-synchronised time and date for corporate offices, schools, hospitals and showrooms.

Sizes & specs

Digit size sets the reading distance

Pick the digit height for how far the board must be read from; everything else — lines, colour, enclosure — is configured around it.

Digit height	Reads from	Typical use	Environment
1″ (25 mm)	up to ~10 m	Counter, panel, instrument repeat	Indoor
2.3″ (57 mm)	up to ~20 m	Workstation Andon, token, clock	Indoor
4″ (100 mm)	up to ~30 m	Line / hall production board	Indoor
6″ (150 mm)	up to ~40 m	Large hall, rate board	Indoor / outdoor
8–12″ (200–300 mm)	up to ~60 m	Forecourt, gate, open yard	Outdoor, weatherproof
SMD matrix (pitch 6–10 mm)	to specification	Alphanumeric, scrolling, multicolour, graphics	Indoor / outdoor

Seven-segment for numeric values; full-matrix SMD for text, scrolling messages, multiple colours and multi-line layouts. Single or double sided; wall, hanging or pole mount.

Representative outdoor board — specification

Smaller indoor boards use lower power, lower brightness and IP20–54 enclosures. Figures shown are a representative build — final specification is fixed against the order.

Interfaces & control

It speaks what your equipment already speaks

The display takes its number from the source you already have — a controller, a sensor, a network or software — with no extra gateway box.

Industrial buses & signals

Modbus RTU (RS485) and Modbus TCP (Ethernet)
Profibus DP for process and PLC networks
RS232 / RS485 serial, direct from controller or instrument
Analog in — 4–20 mA / 0–10 V from a transmitter
Digital I/O — PLC contacts drive count, status and lamps

Network & software

Ethernet & Wi-Fi for networked and remote boards
Driven from Production Genie, Andon, QueSys or the environment logger
Send text, values and screens from a PC or server
API / OPC bridge for third-party and SCADA systems
GPS time input for synchronised clocks

What the board can do

🔢

Value & count

Show a live number, count up or down, hold min / max, and switch colour on a set-point (green / amber / red).

💬

Text & scroll

Fixed or scrolling messages, multi-line and multilingual on matrix boards; sequence several screens in turn.

🔊

Alarm & lamp

Drive a tower lamp, buzzer or hooter with the board — a threshold crossed is seen and heard.

📡

Networked

Address and update many boards over one network; change content centrally from the software.

Tell us the source — the make of PLC / sensor, the protocol and the signal — and the board is configured to read it directly.

Options & ROI

Standard, custom, or networked

From one board on a wall to a network of boards driven by software — the same product family, ordered to the job.

Option 01

Standard board

Proven sizes — counter, Andon, clock, rate, token
Direct from PLC, sensor or serial input
Runs standalone, no server
Quick to quote and deliver

For a single value that needs to be read across a floor or counter.

Option 02

Custom board

Your data, layout, colours and language
Your interface — Modbus, Profibus, analog, I/O
Size and enclosure to the hall / gate / forecourt
Indoor or outdoor, single or double sided

For a display that has to fit an exact requirement.

Option 03

Networked & software-driven

Many boards on one network, updated centrally
Driven by Production Genie / Andon / QueSys / logger
Content, screens and thresholds from software
Scales across lines, halls and sites

For a wall of boards that must stay in step with live data.

Priced by digit size, board size and colour, the interface, indoor / outdoor build, and the number of boards. A firm quotation is prepared against your requirement.

✓

Fits what you own — reads your PLC, sensor or software with no new gateway.

✓

Made to last — 30,000-hour LEDs and metal enclosures; buy once, run for years.

✓

One supplier — board, interface and software from the team that built them.

From a value trapped in a screen — to a number the whole floor can see.
