Group 31 Compact Valve Actuators
Wiring Diagrams
To select the correct wiring diagram you will require the specific
model number of your actuator as well as your feedback type.
4-wire feedback indicates that the Beck actuator (when connected to a
120 V ac supply) will supply the DC voltage to power the position
feedback current loop. This option is the most common.
2-wire feedback indicates that the customer will supply an external DC
voltage supply to power the position feedback current loop regardless of
AC power connections to the Beck actuator.
