Feedback Transmitter Wiring

Connecting feedback transmitters
Terminal 12 and 13 of the VLT provide access to a
24 VDC, 200 mA power supply. This can be used
to power remote transmitters, so an external power
supply is generally not needed. The diagrams below
show how to wire two- and three-wire transmitters.

Two 0 - 10 V feedback transmitter connections:
When two feedback signals are used with the
VLT, both signals must be voltage signals. Both
transmitters must also have the same range.
