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.

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 4 count outputs

Autonomous Vehicle and People Counting for Independent Parking Zones

The NCT100 provides a complete standalone counting solution for sites that need reliable space management without the complexity of networked software. Ideal for single-level car parks, private parking areas, loading bays, warehouse yards and smaller facilities, the compact module mounts easily in roadside cabinets or equipment enclosures and operates autonomously once configured.

With four independent counting channels, a single NCT100 can monitor multiple entry and exit points or track occupancy across several discrete areas simultaneously. The built-in keypad and LCD display allow direct programming without requiring a PC, while alarm outputs trigger Space/Full signs, traffic lights or barrier controls when counts reach preset thresholds. Count values are stored in non-volatile memory, ensuring continuity through power interruptions, and the RS485 port drives up to four variable message signs to keep drivers informed of availability.

Frequently asked questions

What is the counting capacity of the NCT100?

Each of the four counters can record values between -32,500 and +32,500, with the ability to count up or down independently based on configuration.

Can the NCT100 drive variable message signs?

Yes, the RS485 communications port supports up to 4 individually addressable variable message signs displaying count values or status messages.

How do I program the NCT100?

Programming is done directly using the 12-button membrane keypad and 2-line LCD display on the front panel—no PC or special software is required.

What happens if power is lost?

Count values are stored in non-volatile memory, so counts are preserved through power interruptions and restored when power returns.

Can the NCT100 automatically reset counts daily?

Yes, you can set a time when all counters will automatically reset to their predetermined values each day, or trigger a manual reset via the dedicated reset input.
