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.
Model Number Form Factor Major Advantages
Click 100 Din rail Screw terminals for easy wiring to automatic traffic
recorders or data loggers
Click 101 Din rail Collection from multiple sensors
Click 172/174 Rack card Works with standard ITS and intersection detector
racks (NEMA TS1/TS2, 170, 2070)
Click 500 Din rail User-programmable contact closure development
platform for virtually any application.
