Description
The Johnson Controls M9206-GGA-2S is a direct-mount electric spring-return damper actuator - 53 lb·in (6 N·m), AC/DC 24 V, proportional control on a DC 0(2) to 10 V signal, with plenum-rated cable, a 25 to 40 second stroke and no auxiliary switch.
In Johnson Controls' words: "The M9206-xxx-2S Series Actuators are direct-mount, spring return electric actuators intended for use with on/off, floating, or proportional controllers. BGx models operate on AC 24 V power, AGx and GGx models operate on AC/DC 24 V power, and BAx models operate on AC 120 V power. These bidirectional actuators do not require a damper linkage, and are easily installed on a damper with a round shaft up to 1/2 in. (13 mm) in diameter, or a square shaft up to 3/8 in. (10 mm). The M9206-xxx-2S Series Electric Spring Return Actuators provide a running torque of 53 lb·in (6 N·m). Position feedback is provided on proportional control models through a proportional DC voltage signal."
Published specification:
* Running torque: 53 lb·in (6 N·m)
* Control input: DC 0(2) to 10 V, or 0(4) to 20 mA with a field-furnished 500 ohm 0.25 W minimum resistor
* Factory setting: DC 0 to 10 V, clockwise rotation with signal increase
* Action: switch-selectable direct or reverse
* Position feedback: proportional DC voltage signal
* Supply: AC 24 V ±25% at 50/60 Hz, Class 2, typically 12.0 VA running and 5.0 VA holding; or DC 24 V ±10%
* Rotation time: 25 to 40 seconds
* Rotation range: mechanically adjustable
* Shafts: round up to 1/2 in. (13 mm) diameter; square up to 3/8 in. (10 mm)
* Electrical connection: 48 in. (1.2 m) 18 AWG UL CMP plenum-rated cable with 1/4 in. (6 mm) stripped wire leads
* Auxiliary switch: none - see the M9206-GGB-2S
* Valve mounting: VG1000 Series forged brass ball valves via M9000-513 or M9000-520 linkage kit
Plenum-rated cable, on the proportional model. The GGA-2S ships with UL CMP plenum-rated cable, which is what allows it to be installed in environmental air spaces such as the void above a hung ceiling. The on/off models in the same series ship with standard halogen-free AWM cable instead. If the actuator is going above a ceiling that handles return air, the cable rating is not optional - check it before substituting a cheaper code.
Important: this is the -2S, not the -2. Johnson Controls has published two generations of the M9206 under near-identical codes. This one strokes in 25 to 40 seconds. If you are replacing a failed unit on a commissioned sequence, match the suffix - and note the earlier M9206-GGA-2 also accepts a 6 to 9 VDC input for legacy pneumatic-to-electric panels, which this model is not published as supporting. If your panel drives 6-9 V, ask us before ordering the -2S.
The 500 ohm resistor is field-furnished. For 4-20 mA operation Johnson Controls specifies a "field furnished 500 ohm, 0.25 W minimum resistor" - it is not supplied in the box. Tell us if you are wiring a current loop and we will include one.
Set up on the actuator, not in the panel. The unit is "factory set at DC 0...10 V, CW rotation with signal increase", with "switch selectable direct or reverse action" - so a reversed sequence is a switch setting rather than a re-wire or a different part number. "Automatic stroke calibration at installation" means the actuator learns its own travel limits, which Johnson Controls says "reduces installation time and costs".
Proportional, not two-position. If your controller only has a switched output, the on/off M9206-BGx-2S is cheaper and faster at 10 to 40 seconds; for tri-state floating control from a triac or relay, the M9206-AGx-2S.
Spring return means fail-safe. The actuator returns to its normal position on loss of power, and the reversible mounting design enables the actuator to spring return in either direction - set by which way you mount it.
Other features, in the manufacturer's words: "simple direct coupling reduces installation and commissioning time while improving reliability by eliminating damper linkages. Single screw coupling provides three-point shaft gripping"; a "removable coupler adapts to a shorter damper shaft"; and "electronic stall detection throughout entire rotation range extends the life of the actuator by deactivating the actuator motor when an overload condition is detected."
