Large digital LED displays with big digits.

New: Versions now available with Atex certification

The Fusion series of Large LED displays makes perfect commercial sense, even when compared to much lower cost versions.


They are easy to use, so you can install and commission them in a fraction of the time you'd need for displays from other manufacturers. You won't need to spend hours on the phone talking to technical support. Time is money!

Plus, they are reliable, there are many displays mounted in harsh conditions, even outside, which are still working perfectly well after more than 25 years of 24/7 operation.

Large display Output Options

Our big digit Fusion displays also have a wide range of useful output options:-

  • 0-10V, isolated and fully scalable
  • 4-20mA, isolated and fully scalable
  • 2 Alarm relays
  • 4 Alarm relays
  • RS232
  • RS485

Sensor Excitation

Sensor excitation is included as standard. For example, on our load cell large digit displays, we provide a 10V DC excitation output, rated to 120mA, to power up to 4 x 350 Ohm load cells.

On our 4-20mA input large displays, we provide 24V DC rated to 30mA, ideal for powering 2 wire 4-20mA transmitters.

Similarly on our counter and rate meter large displays, we provide a 24V DC excitation supply which is suitable for most NPN, PNP and contact closure sensor types.

How to connect our displays to popular fieldbus networks such as Profibus, Ethernet I/P, CanOpen, DeviceNet, TCP/IP, RS232, RS485

industrial fieldbus profibus ethernet IP gateway With the use of HMS industrial network gateways such as the AB7000 range, you can connect our displays to almost any industrial network type.

The gateway device mounts in an area with an available network connection and sends RS485 to our display.

We recommend that the gateway device be mounted in an accessible location, such as a PLC cabinet, so that you can easily configure it and view its diagnostic indicators.

HMS have an extensive technical library to help you to configure your gateway to your requirements.

What size characters do I need?

With London Electronics displays, you have a wide choice of character heights for different viewing distances.

You should measure the maximum viewing distance you'll need, and use this chart to work out the ideal character size for you.

This will make sure you won't have to struggle to read the display. And, you won't pay too much for a display which is bigger than you need.
