•
Supplies 12 Vdc/210 mA power to the Rnet across its rated temperature
range.
NOTE Ambient temperature and power source fluctuations exceeding the
listed operating ranges may reduce the power supplied by the Rnet port.
NOTE If the total power required by the sensors on the Rnet exceeds the power
supplied by the Rnet port, use an external power source. The Wireless Adapter,
Equipment Touch, or TruVu™ ET Display must be powered by an external power
source. See the specifications in each device's Installation and Start-up Guide to
determine the power required.
