Field Wiring
24 V powered
transducer with 1-10
VDC output
24 V external power
supply common to field
device and controller.
Power can be 24 VDC or
VAC as required by the
field device.
Transducer with 1-10
VDC output
External power supply for
field device (depends on
field device requirements)
and 12 VDC external
power supply for
controller.
Connect the negative or
common of both power
supplies to the
0V
terminal of the controller.
Transducer with 1-10
VDC output
External power supply for
field device (depends on
field device requirements)
and 24 V external power
supply for controller.
Connect the negative or
common of both power
supplies to the
0V
terminal of the controller.
2-wire transducer with 4-
20 mA or 0-20 mA output
Connect an external 250
Ω ½ Watt 1% load
resistor in parallel
between the universal
input terminal and
0V to
provide a return path for
the transducer signal
current.
12 VDC power supply
common to field device
and controller.
