As well as time of day, our Fusion clock displays can be used as elapsed timers, either counting up from 0 or counting down from a preset time. These are ideal in Takt timing applications, process curing and as count-down displays to a big event. They are also ideal for showing factory safety data such as days since last accident, with automatic day counting and simple preset and reset functions.

"We had a specific requirement for our station timers and London Electronics were not fazed by this at all.

James visited our site with demo models and explained very clearly what he needed from us in order to get the best product.

We had changing circumstances in our project and LE responded quickly to all. When faced with meeting a much earlier deadline than expected they really pushed on so we could get all the timers we needed.

Overall they are very professional company, the products they have supplied are top quality and I will be using them in any further projects."

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.

Cloud based clocks with alarms and messaging

We can also provide large cloud-based LCD clocks synchronised to network time, which can contain break time information, sound triggers, moving text messages etc.

Synchronised factory clocks with alarm sounders

We can provide clocks which are wireless-linked for synchronisation and include sounders to alert your team of breaks.

The schedule can be set up on a PC application we provide free of charge.

Please see example below. Click the software pane to download the software as a zipped file.

Factory Clock alarm / sounder scheduling software
This Windows software allows you to create a schedule of timed events, which can be tailored for each day. By including alarm relays in your clock, the clock can control sounders, lights, interlocks etc. Timing can be for a short duration of a few seconds, ideal for sounders, or can span hours.

You can have up to 4 alarm relay channels to control up to 4 individual devices, each with different timings.
