One and two input third generation Counters introduced

New panel mounting pulse input counters can perform most industrial counting operations in hazardous and safe areas including position indication.


  • Separate easy to read total and rate displays
  • Choice of three enclosures, all with IP66 fronts:
        144 x 72mm
        96 x 48mm
        105 x 60mm rugged stainless steel
  • ATEX, IECEx, ETL and cETL certified models:
        Ex ia intrinsically safe applications
        In Zone 0, 1, 2 or Div 1, 2
        Ex nA non sparking applications
        In Zone 2 or Div 2 without without Zener
        barriers or isolators

  • General purpose models
  • Two input models can display the sum or difference of the inputs and shaft position when used with a quadrature encoder.
  • Accessories:
        Isolated dual alarms
        Isolated synchronous pulse output
        Isolated 4/20mA output
  • Three year guarantee

All models can simultaneously display the total number of pulses received and the pulse rate in the same or different engineering units. The two input Counters can also display the sum or difference of the two inputs, and when connected to a quadrature shaft encoder, display the position, speed and direction of the shaft or cable. The instruments are easy to configure on-site and are supported by comprehensive documentation, but can be supplied ready to install with customer specified configuration and scale card units of measurement for no additional charge.
