shield
Vented polycarbonate shield
0.5 in. (1.27 cm) outside diameter
1.2 in. (3.05 cm) long with 1/2 in. NPT threads
Power requirements 12 Vdc @ 6 mA
Power supply The 4-conductor Rnet cable from a controller supplies +12 Vdc @ 210 mA. For
additional power, use an external power supply. Use the above power requirements to
calculate the size of the external power supply. The controller and the external power
supply must share a common ground.
Communication 115 kbps
Mounting 3/16 in. holes
Listed by FCC Part 15-Subpart B-Class B, CE
To address a ZS immersion temperature sensor
Each ZS Sensor on an Rnet must have a unique address, but addresses do not have to be sequential.
Open the hinged cover on the sensor enclosure, and then use the DIP switches to set an address from 0 to 14. (1
is factory default.) Each DIP switch has the value shown in the figure below. Turn on as many DIP switches as you
need so that their total value equals the address.

DIP switches 1 and 4 above
are on. Their values (1 + 8) total 9, so
the sensor's address is 9.
