What is a Control Option?

Group 29 Beck linear actuators have a model number 29-100, 29-250, or 29-600. This drive has the capability to be equipped with different electronics combinations, which are called control options. The control option number will replace the last zero in the model number when specifying a drive model and control option. For example, a model 29-100 drive that is setup to use the control option 9 electronics would be considered a model 29-109 drive. A basic description for each control option is provided below. For details on the electronics components, please visit the Group 29 Electronics section.

CONTROL OPTION	DESCRIPTION	CONTROL MODE	INSTALLED CONTROL BOARD	STANDARD CONTROL INPUT	INSTALLED POSITION SENSOR	STANDARD POSITION FEEDBACK
9	The standard modulating drive offering is the control option 9. Control option 9 units are equipped with the Beck DCM (Digital Control Module) and CPS(Contactless Position Sensor). The option 9 drives may be controlled with a 4-20 mA or 1-5Vdc signal and have an integral 4-20 mA position feedback signal. The microprocessor based DCM provides a multitude of flexibility for setup, calibration, and diagnostics including HART communications, on-board pushbuttons for calibrating stroke, on-board diagnostic status, stall protection circuitry, and status alerts.	Modulating	DCM	4-20 mA	CPS	4–20 mA
3	The control option 3 drive is an open/close unit controlled with 120 VAC direct to the motor. When the drive hits the limit switch at either of the two end-of-travel positions, power is cut to the motor.	2-position (open/close)	None	120 V ac	None	None
