88 CHAPTER 9 CONTACT CLOSURE COMMUNICATIONS
Click 100 – e Click 100 is a din rail–mounted contact closure that can be used in
cabinets without detector racks and simplies integration into automatic data record-
ers and data loggers. e wiring harness of the automatic data recorders can connect
directly to the screw terminals of the Click 100. Application notes for wiring to com-
mon automatic trac recorders can be obtained by contacting your authorized Wa-
vetronix dealer or Wavetronix Technical Services.
Click 101 – e Click 101 has the built-in capability of collecting from multiple Smart-
Sensor units simultaneously, making it an excellent choice for midblock applications.
is allows one Click 101 to collect trac data from all the SmartSensor stations
pertaining to an intersection. For arterial management, the resulting system is very
cost-eective and can be rapidly deployed, especially when wireless communications
is included.
Each SmartSensor uses its two communication ports to send real-time trac data to
both cabinets for which it is collecting data (see Figure 9.1). e real-time data is used
to control the intersection using either local control strategies or closed-loop control
systems like ACS-lite.

Click 172/174 – e Click 172/174 are contact closure cards that allow the SmartSen-
sor to integrate into standard ITS and intersection detector racks. e Click 172 has
two contact closure outputs and the Click 174 has four. e Click 172/174 are com-
monly used in legacy ITS cabinets or for midblock intersection detection. Multiple
modules can be daisy-chained together to collect data from all eight lanes possible
with SmartSensor.
Unlike the Click 101, which actively collects information from multiple sensors, each
Click 172/174 is dedicated to a single sensor. During programming, the Click 172/174
cards transmit conguration information to SmartSensor to set up the mode of opera-
tion. Once the mode is set up, the rack cards stop transmitting messages and passively
listen for data pushed by the sensor.
