M9220-BDC-3 Johnson Controls Actuator

Datasheet

The information in this section assumes that Side A of the actuator (CCW spring return) is facing you and the control selector switch is set to the 0 …10 V CW position.
The actuator is powered with AC/DC 24 V power between the black (common) and red (+AC/DC 24 V) wires. A proportional controller provides a DC 0 to 10 V signal between the black (common) and gray (control signal input) wires.
As the control signal increases from DC 0 to 10 V, the actuator drives CW from the -5 to 90° position. The position at which the actuator stops is proportional to the control signal. The actuator provides about 120 steps of control.
As the signal decreases, the actuator reverses direction and drives CCW toward the -5° position. A DC 0 to 10 V feedback signal is provided between the black (common) and orange (DC 0 to 10 V feedback signal output) to indicate the position of the actuator.
The direction in which the actuator drives with an increasing control signal can be reversed by positioning the selector switch to the DC 0… 10 V CCW position. When the actuator is placed in this position, and it is at the 90° position with a DC 0 V control signal, the actuator proportionally drives to the -5° position as the control signal increases.
The actuator spring returns when power is interrupted between the black and red wires. When power returns, the actuator drives to the fully spring-return position to establish an end-of-stroke position, then drives to the position commanded by the DC 0 to 10 V controller.
This model has a selector switch that provides operation for DC 2 to 10 V controllers. This switch allows a CW or CCW rotation as the control signal increases from DC 2 to 10 V. The feedback signal between the black and orange wires changes to DC 2 to 10 V when the input signal selector is set to the DC 2…10 V CW or CCW position.
The M9220-GGx-3 actuators can be controlled by a DC 0 to 20 mA or DC 4 to 20 mA controller by placing a field furnished 1/4 watt 500 ohm resistor between the black (common) and orange (+DC 0[4] to 20 mA control signal input) wires
