Product Features & Benefits

The NCT100 standalone counter can be combined with one or more Variable Message Signs to provide information of space availability to staff and visitors.

Alarm outputs can be associated with each counter to indicate that the count has reached a predetermined value. These can be used to operate Open/Full signs, traffic lights, barrier controls or other devices that require an input based on a count value.


  • Simple, cost effective means of providing count management for a wide range of applications and any size of car park
  • Count values are stored in non-volatile memory to guard against temporary loss of power
  • Extremely flexible - a single module can provide up to 4 counters or one counter with up to 4 increment and 4 decrement inputs
  • Powerful VMS driving capability. Can provide up to 4 count outputs
