*1 The PTs cannot be connected to OMRON PLCs using RS-485 (2-wire)
connections and the Host Link protocol.
*2 "+" and "−" are the power supply pins to drive the PT.
*3 Be sure to consider the cable length and ensure that the voltage supplied
to the PT is within the operating voltage range.
*4 If power is being supplied from a source other than the PLC for a PT with a
5-VDC power supply, make sure the power supply cable is 10 m or less in
length.
