Field Wiring
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.
24 VDC power supply
common to field device
and 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.
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.
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.
3-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.
24 VAC power supply
common to field device
and controller.
