Description
The Johnson Controls M9210-BAC-3 is a direct-mount electric spring-return damper actuator - 89 lb·in (10 N·m), AC 120 V line voltage, on/off (two-position) control, with two integral line-voltage auxiliary switches.
In Johnson Controls' words: "The M9210-xxx-3 Series Actuators are direct mount, spring return electric actuators that operate with these available power options: AC 24 V at 50/60 Hz or DC 24 V (AGx, BGx, GGx, HGx), AC 120 V at 60 Hz (BAx), AC 230 V at 50/60 Hz (BDx). These bidirectional actuators do not require a damper linkage, and are easily installed on dampers with 1/2 to 3/4 in. or 12 to 19 mm round shafts, or 3/8 and 1/2 in. or 10, 12, and 14 mm square shafts using the standard shaft clamp included with the actuator. The M9210-xxx-3 Series Electric Spring Return Actuators provide running and spring return torques of 89 lb·in (10 N·m). Integral line voltage auxiliary switches are available on the xxC models to indicate end-stop position, or to perform switching functions within the selected rotation range."
Published specification:
* Running torque: 89 lb·in (10 N·m)
* Spring return torque: 89 lb·in (10 N·m) - the same, with and without power
* Control: On/off (two-position)
* Supply: AC 120 V at 60 Hz
* Auxiliary switches: two, integral, line-voltage capable
* Rotation time (M9210 on/off models): 24 to 57 seconds running; 11 to 15 seconds spring return
* Shafts: round 1/2 to 3/4 in. (12 to 19 mm); square 3/8 and 1/2 in. (10, 12 and 14 mm) - standard shaft clamp included
* Electrical connection: 48 in. (1.2 m) 18 AWG appliance cable
* Jackshaft option: M9220-600 Jackshaft Coupler Kit for round 3/4 to 1-1/16 in. (19 to 27 mm) or square 5/8 and 3/4 in. (16, 18 and 19 mm)
Check the second letter. There are three supply voltages in this range and they differ by one character.
* M9210-BGC-3 - AC 24 V at 50/60 Hz or DC 24 V
* M9210-BAC-3 - AC 120 V at 60 Hz (this item)
* M9210-BDC-3 - AC 230 V at 50/60 Hz
All three are 89 lb·in, on/off, spring return, two switches, and physically indistinguishable. They are not interchangeable. Connecting 120 V to the 24 V unit destroys it instantly and energises a circuit an installer will reasonably treat as Class 2; 24 V onto this one will not move it and the fault gets chased elsewhere.
Note also that the switches are line voltage, and that is a second circuit to get right. Johnson Controls describes the xxC contacts as "integral line voltage auxiliary switches". On a 120 V actuator that means two separate line-voltage circuits on one device - the supply and the switched contacts - and they need not be at the same potential. Label them at the panel.
No control transformer needed. Wire the actuator straight to the 120 V circuit that switches it.
Two-position only. Powered open, spring closed. There is no floating-point input and no analogue input - and note Johnson Controls offers line voltage on the on/off models only. The floating (AGx), proportional (GGx) and adjustable-span (HGx) M9210 models are all 24 V, so a 120 V site needing modulating control will also need a transformer.
Spring return means fail-safe. Johnson Controls rates the full 89 lb·in both running and spring returning, so the spring closes the damper against its seal rather than letting it drift back - in 11 to 15 seconds.
Bigger shafts than the M9208. This series takes a 1/2 to 3/4 in. (12 to 19 mm) round shaft as standard, where the 70 lb·in M9208 starts at 5/16 in. If you are stepping up in torque, check the shaft - the larger actuator has a larger minimum, not just a larger maximum. For 3/4 to 1-1/16 in. jackshafts, add the M9220-600 coupler kit.
