These models should only be used for applications that require high gain. Consult Baker Hughes prior to selecting these models.

Remote Setpoint Change Options

• The SM-1000 series motors accept a 24 VDC or 120 VAC input. The SM-1100 series motors accept a 4-20 MA signal and require

a separate 24 VDC or 120 VAC power connection.

• The total motor rotation is adjustable. The maximum number of motor rotations possible coupled with the spring rate determines

the total setpoint range.
