HVAC actuator with removable cartridge
An actuator for a HVAC system includes a base having a motor and a drive device driven by the motor and configured to be coupled to a movable HVAC component for driving the movable HVAC component between multiple positions, and a removable cartridge removably attached to the base.
1. An actuator for an HVAC system, the actuator comprising:
a base including:
a motor; and
a drive device driven by the motor and configured to be coupled to a movable HVAC component for driving the movable HVAC component between multiple positions; and
a removable cartridge removably attached to the base, the removable cartridge comprising a transmission having an input connected to the motor and an output connected to the drive device, wherein the removable cartridge is smaller than the base.
2. The actuator of claim 1 , wherein the removable cartridge includes an input device, an output device, and a processing circuit.
3. The actuator of claim 1 , wherein the removable cartridge includes an input device and a processing circuit.
4. The actuator of claim 1 , wherein the drive device defines an opening configured to receive a shaft of the HVAC component.
5. The actuator of claim 1 , wherein the base includes a base processing circuit, a first connection port, and a second connection port electrically coupled to the base processing circuit.
6. The actuator of claim 5 , wherein the second connection port is a mirror image of the first connection port.
7. The actuator of claim 5 , wherein the removable cartridge includes an input device and a cartridge processing circuit.
8. The actuator of claim 7 , wherein the base includes a plurality of base terminals and the cartridge includes a plurality of cartridge terminals and wherein the base terminals engage the cartridge terminals to complete an electric circuit when the cartridge is attached to the base.
9. The actuator of claim 7 , wherein the base includes a projection and a plurality of base terminals located on the projection;
wherein the cartridge defines a cavity; and
wherein the cavity receives the projection when the cartridge is attached to the base so that the base terminals are located near the cartridge processing circuit.
10. An actuator for an HVAC system, the actuator comprising:
a base including a motor and a drive device driven by the motor and configured to be coupled to a movable HVAC component for driving the movable HVAC component between multiple positions; and
a removable cartridge removably attached to the base, wherein the cartridge includes a cartridge processing circuit and a transmission, wherein the transmission comprises an input connected to the motor and an output connected to the drive device, and wherein the removable cartridge is smaller than the base.
11. The actuator of claim 10 , wherein the removable cartridge also includes an input device and an output device.
12. The actuator of claim 10 , wherein the removable cartridge includes an input device.
13. The actuator of claim 12 , wherein the input device is at least one of a button, a switch, a dial, a knob, a touchscreen, and a keypad.
14. The actuator of claim 10 , wherein the base includes a base processing circuit, a first connection port, and a second connection port electrically coupled to the base processing circuit.
15. The actuator of claim 14 , wherein the second connection port is a mirror image of the first connection port.
16. The actuator of claim 14 , wherein the base includes a plurality of base terminals and the cartridge includes a plurality of cartridge terminals and wherein the base terminals engage the cartridge terminals to complete an electric circuit when the cartridge is attached to the base.
17. The actuator of claim 14 , wherein the base includes a projection and a plurality of base terminals located on the projection;
wherein the cartridge defines a cavity; and
wherein the cavity receives the projection when the cartridge is attached to the base so that the base terminals are located near the cartridge processing circuit.
18. An actuator for an HVAC system, the actuator comprising:
a base including a drive device configured to be coupled to a movable HVAC component for driving the movable HVAC component between multiple positions; and
a removable cartridge removably attached to the base, wherein the cartridge includes a transmission having an output connected to the drive device, and wherein the removable cartridge is smaller than the base.
19. The actuator of claim 18 , wherein the base includes a motor connected to an input of the transmission.
20. The actuator of claim 18 , wherein the cartridge includes a motor connected to an input of the transmission.
