diagrams on these pages use an externally powered sensor (connections not shown).
The figures below gives example of a connections using a two-wire or three-wire
sensor/transmitter supplied by the drive auxiliary voltage output.
Note: Maximum capability of the auxiliary 24 V (200 mA) output must not be
exceeded.

Note: The sensor is supplied through its current output and the drive feeds the supply
voltage (+24 V). Thus the output signal must be 4...20 mA, not 0...20 mA.
