Programmable Large Digit Rate/Frequency Displays From Eagle Controls


MODEL LDDRF-2000 Programmable Large Digit Rate/Frequency Displays

Programmable,Large,Digit,Rate,Frequency,Displays,Eagle Controls




The LDDRF-2000 is a 5 digit fully scaleable Quartz Crystal stabilised pulse input Rate/Frequency meter accepting Contact Closure, PNP or NPN proximity sensors and voltage pulses from 10.5 to 30V. They are ideal for production line monitoring, showing units per shift, frequency monitoring or generator frequency. They are able to average over long periods with irregular input rates.

The displays are available in 3 digit sizes and may be Panel, Wall or Suspension mounted in IP55 / NEMA 12 rugged aluminium enclosures and are supplied with the necessary hardware. They have a universal switch mode power supply across the range 90-265Vac and are CE, UL and CSA approved.

The LDDRF-2000 is suitable for any application where data needs to be viewed from a distance, from murky environments of heavy processing industries to clean room Laboratory applications.
