 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.
