LARGE LED TIMERS – APPLICATIONS
The use of these Timers is very wide, applications include:
- Measuring assembly line down time.
- Controlling a process or event by Time alone.
- Calculating process efficiency.
- Measuring Time taken for line changeovers.
- Measuring TAKT Time.
- Measuring a total event or process Time.
- Improving employee motivation.
- Sports Time events …etc.
ANYTHING THAT CAN BE MEASURED IN RELATION TO TIME
LARGE DISPLAY LINES
The Large LED Timers can be supplied in SINGLE LINE or MULTILINE format and the Multiline displays can be a mix of Time Bases.
Examples of Single and Multiline Timers with Different Time Ranges
LARGE DIGIT LED TIMER – DESCRIPTIONS And Uses
Up or Down Timers ( And TAKT Time }
UP TIMERS can also be called TIME TOTALISERS, whereby an INPUT START SIGNAL initiates the Timing UP from Zero to a PRESET VALUE or continues to TIME UP until the maximum scale range is reached, In both cases an OUTPUT SIGNAL can be provided.
DOWN TIMERS/ TAKT TIME can also be called BATCH TIMERS, whereby a PRESET VALUE is set for a period of Time that an event has to take place. When that Time is reached, normally at Zero an OUTPUT SIGNAL can be provided.
This is typical of TAKT TIMING, where an operation must be completed within a set time.
Our Timers can, at ZERO, in such circumstances show NEGATIVE TIME and even the LEDs can change colour to show the SET TIME has been exceeded.
STOP WATCH
This functions as its name suggests as a STOP WATCH, for INDUSTRIAL or SPORTS events in particular, where the Time needs to be STARTED and STOPPED and RECORDED and either RESET or continues to TIME.
These are usually UP TIMERS.
These functions can be manually controlled or through SERIAL communication.
Totalisers
TOTALISERS are dedicated to the task of displaying TIME ELAPSED and are usually UP TIMERS.
They ( like all the previously described Timers ) are available in all the Time Bases listed earlier and are usually used to display Time only with no OUTPUT function.
Many of these type of Timers are used to display POWER USEAGE like ‘ kWh ‘ or similar.
They accumulate rather than simply display usage.
Day Timers
DAYS TIMERS are LONG RANGE Timers, usually UP TIMING from Zero and invariable used with HRS : MINS and sometimes SECS.
They can also be used a DOWN TIMERS where a set number of DAYS is entered remotely and when the Timer receives a START SIGNAL INPUT, will start Timing Down and every 24 hours the DAYS will decrease by one.
In both cases these Timers are used to show the Time elapsed before an EVENT takes place or the Time left before an EVENT takes place.
LARGE DIGIT LED Timers HEIGHT OPTIONS
All these Timers are available in the following LED DIGIT sizes:
2.3” (58mm), 4” (102mm), 6” (150mm), 8” (200mm), 12” (305mm), 16” (410mm), 18” (457mm).
Larger digits are available depending on quantity.
VIEWING DISTANCES FOR LARGE DIGIT TIMERS AND TOTALISERS
The maximum viewing distances for the DIGIT SIZES given below are based on the LED manufacturers specifications and give CLEAR UNAMBIGUOUS READING. They are NOT to be taken MAXIMUM distances and normally viewing distance will be less than the maximum figure given.
DIGIT HEIGHTS | VIEWING DISTANCES |
|---|---|
| Actual | Guide Only |
| 2.3” (58mm) | 15 meters / 50 feet |
| 4” (102mm) | 35 meters / 115 feet |

| 18″ (457 mm) | 170 metres / 557 feet |
HIGH BRIGHTNESS DAYLIGHT VIEWING LEDS
High brightness LEDs are used for OUTDOOR applications but can also be used for INDOOR environments where it might be murky to ensure visibility at all times.
LARGE LED TIMERS – REMOTE BOX OPTIONS / IR REMOTE
The Large Digit Timers can be set for TIME, START / STOP / RESET and OUTPUT functions.
The Remote Boxes are plug-in via a 5 meter cable and ‘ D ‘ type connector or they can be controlled with an IR Remote. The plug-in Remote Boxes can be hand held or fixed to a Wall / Surface, whereas the IR Remote is purely hand held with a 10 meter send and receive operating distance.
