Description
The Johnson Controls M9208-GGA-LX is a direct-mount electric spring-return damper actuator from the M9208 Series - 70 lb·in (8 N·m), 24 VAC/VDC, proportional control with 0(2) to 10 VDC position feedback and no auxiliary switches.
In Johnson Controls' words: "For proportional modulation of dampers requiring up to 70 lb·in. (8 N·m) in HVAC systems that are controlled by an electronic controller or positioner. The actuator responds to 0 to 10 VDC, or 2 to 10 VDC control signals. With the addition of a 500 ohm resistor, the actuator responds to a 0 to 20 mA, or 4 to 20 mA signal. A 0 to 10 VDC, or 2 to 10 VDC feedback signal indicates position and provides support for master-slave applications."
Confirmed from the GGA letters and from specifications Johnson Controls states for the whole series:
* Rated torque: 70 lb·in (8 N·m), running and spring returning, at all operating temperatures
* Control input: DC 0(2) to 10 V, or 0(4) to 20 mA with a 500 ohm resistor
* Feedback signal: DC 0(2) to 10 V, supporting master-slave applications
* Supply: 24 V - Johnson Controls offers the proportional M9208 models on 24 V power only
* Rotation: 95° of rotation; adjustable stop 35° to 95°; graduated scale from -5° to 90° with position indicator
* Shaft: 5/16 to 5/8 in. (8 to 16 mm) with the standard universal clamp; to 3/4 in. (19 mm) with the M9208-600 coupler kit
* Auxiliary switches: none
* Spring return: yes - fail-safe, rated torque with and without power
Please confirm the cable format with us before ordering. Johnson Controls' M9208 ordering table runs a clean set of numeric -2 and -3 tails throughout. This item is labelled -LX, a letter tail that appears nowhere in the manufacturer's literature we can find.
Everything above follows from the GGA letters or from series-wide statements, so it holds regardless of the tail. What we have not stated is the cable, because that is precisely what the tail encodes in this series: the -2 ships with a 120 in. (3.05 m) 19 AWG plenum-rated cable, the -3 with a 48 in. (1.2 m) cable and integral 3/8 in. (10 mm) flexible metal conduit connectors. If this actuator is going above a return-air ceiling, the cable rating is a code question, not a preference - send us a photo of the nameplate and we will confirm before it ships.
A letter tail is a different animal from a number tail, and worth a moment. Elsewhere in this range Johnson Controls uses letter suffixes for genuinely separate product lines rather than for typos - the M9203-xxx-RK series, for instance, is a real JCI range published under its own document and catalogued by a damper manufacturer for factory-mounted applications. -LX may well be something of that kind: an OEM, equipment-maker or regional variant. Read the label - if it names a damper or equipment manufacturer, that is your answer.
The voltage is not in doubt. In the M9208 range the supply is the second letter: G is 24 V, A is 120 V, D is 230 V. The proportional models are published on 24 V only, so a GG code cannot be a line-voltage part whatever the tail says.
Master-slave capable, through the 0(2) to 10 VDC feedback signal.
Override control, through field wiring - a proportional-model-only feature. Separately, a locking manual override with auto release allows "manual positioning of the actuator hub with automatic return to normal operation when power and control signal are restored", with crank storage on the unit.
Spring return means fail-safe. Full 70 lb·in is rated with and without power applied. Direction is set by mounting: face A away from the damper gives counterclockwise spring return; face B away gives clockwise.
