In many applications, you will not need to use your SmartSensor with contact closure cards.

Often traffic data is collected directly from the sensor via a serial, modem or Internet con-

nection. However, a contact closure module is often needed to use a SmartSensor with a

traffic controller, traffic data recorder or other type of data logger.

Selecting the Contact Closure Model

In some applications, all of the contact closure modules listed in Table 9.1 below could be

used, but one model may have major advantages over the others; for example, the Click 101

is better for midblock applications.
