The PC-10 monitors the number of people entering and leaving an enclosure and uses a traffic light display, combined with a buzzer, to control the flow. This is very useful in environments such as retail., restoration, pharmacies or service providers where the volume of people in confined spaces may make it difficult to maintain the recommended safety distance from others.

Houses two Sick multibeake safety light barriers, that detect the direction of movement, together with a lococube Barth mini-PLC STG-800, which has one CAN bus and five I/O interfaces.

The PC-10, that for its operation does not require an Internet connection, continuously calculates the number of people entering and leaving the stay in real time.

On the back of the unit is a password-protected Barth DMA-15 2.4in CAN color HMI touchscreen, which provides the user interface and allows store owners to predetermine the maximum limit of people.

The PLC also powers the five included 12V/3W Led modules, that serve as a traffic light system, illuminating the 'Go' indicator in green when access is granted and 'Stop' in red when access is denied. The Buzzer, also located at the rear, acts as an audio alert.

Power is supplied by a DC connector connected to a 12V AC/DC power adapter. A 90-230VAC outlet is sufficient for operation.
