Large Display totalisers / counters

These large displays accept most common pulse inputs such as contact closures, NPN or PNP proximity sensors, 24V PLC pulses etc. They can easily be scaled give 1 count per pulse, or to read in your preferred engineering units.

Because the scaling is digital, precision is excellent. Scale factors can be non-whole numbers, for example 1.245 etc.

The displays have a 24V excitation output voltage which you can use to power active sensors and encoders..

You have several digit sizes to choose from, to suit the viewing distance you need.

Suited for these applications and more:-

• Production counting and display [Special page]
• Material length counting and display
• Distance counting and display
• Manufacturing cycle time
• Rejects counting and display
• Any physical variable having a pulse signal

This page has 2 models for you to choose from:-

[ERXC] [T17XX]

[^] Easy-Reader series of large counting displays
The Easy Reader series are our most economical range of large displays. The can be set to function as counters, ratemeters, timers, period meters, quadrature meters and frequency meters. They are attractively styled and particularly easy to use. Wall or suspension mounting hardware is available. Dustproof enclosures suit general industrial environments. All settings, including the count, are stored in 10 year memory.

[^] T17XX Series of large counters / totalisers
The T17XX series is a family of sealed counter / totalizer displays which can be wall mounted, suspension mounted or panel mounted. They offer a wide range of digit sizes, brightness options, and led colours. They can also be used to create custom-made multi-line numeric displays for production monitoring and displaying general manufacturing performance. Scaling and adjustment can be done remotely.
Input connections	2 channel input and 24V Excitation Suits direct connection, 2 wire active or passive loop and 3 wire sensors. Debounce filters available for contact closure inputs.
Input Signals	Input signals selected by push-on jumpers... NPN Sensors PNP Sensors Contact closures Quadrature encoders Frequency response:- 0 to 50 000 Hz for single I/P Frequency response:- 0 to 10 000 Hz for dual I/P
