Product Features & Benefits

The NCT200 can be networked to a server via either RS485 or TCP/IP as a part of a count management system. The outputs from the NCT200 can be controlled directly from the software to support centralised control of signs, alarms, door/barrier control arming, etc.

In standalone mode it operates in exactly the same way as the NCT100.

benefits

  • 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 8 count outputs when online (assigned in count management software).
