Control Option 2 - Typical Arrangement


CONTROL OPTION 2 - The control option 2 drive, consisting of model numbers 31-350 and 31-330, is a modulating unit controlled with 120 VAC direct to the motor. These units provide an integral 4-20 mA or 1-5 Vdc position feedback signal that is configured for a 4-wire setup, but may be of the 2-wire variety if specified at the time of order. When the drive hits the limit switch at either of the two end-of-travel positions, power is cut to the motor.
