The Pro-Sign vehicle counter, available from O'Briens Automatic Systems , keeps track of vehicles entering car parks. Customers can simply preset the vehicle counter to the number of empty parking bays. As vehicles enter the facility, the counter counts down showing the number of available bays. When there is no more space available the output relay is energised. This relay can be used to switch on a full sign to indicate the facility has no more space.
The counter incorporates battery backed memory and will maintain its count value during a power fail condition. The maximum count value is 999999 (six digit display).
Following are the features of Pro-Sign vehicle counter:
- Separate up/down counter inputs: Two separate inputs allow the counter to be used as an up counter, down counter or both simultaneously.
- Battery backed-up counter: In the event of power failure, the counter and alarm preset values are maintained.
- Upper and lower alarm: Two relays are used to give alarm outputs when the counter has counted up to an upper limit or counted down to zero.
- Built in power supply: The built in power supply enables potential free contacts to be used without the need for an additional power supply.
- Physical Size: 330mm (w) x 97mm (h) x 66mm (d)
The Pro-Sign 6 digit counter is a high brightness 6-digit LED display incorporating a built in up/down counter. The unit includes two relay trip outputs for upper and lower alarm outputs. RS485 Modbus communications enables many counters to be networked together back to a PLC or PC.
