Electric Non-Spring Return Actuator, 0-10 VDC
Quantity in Basket: None
M91xx Series Electric Non-spring Return ActuatorThe M91xx Series includes M9108, M9116, M9124, and M9132 models. All of these direct-mount electric actuators operate on 24 VAC or VDC power. The M91xx actuators are available for use with on/off, floating, proportional, or resistive controllers. These bidirectional actuators do not require a damper linkage, and are easily installed on a damper with a round shaft up to 3/4 in. (19 mm) in diameter or a square shaft up to 5/8 in. (16 mm). They may be direct or remote mounted to a damper or mounted to a valve using one of the M9000-5xx Valve Linkage Kits.
A single M91xx model delivers up to 280 lb·in (32 N·m) of torque. Two AGx, GGx, or HGx models in tandem deliver twice the torque or 560 lb·in (64 N·m). The angle of rotation is mechanically adjustable from 0 to 90° in 5-degree increments. Integral auxiliary switches are available to indicate end-stop position or to perform switching functions at any angle within the selected rotation range. Position feedback is available through switches, a potentiometer, or a 0 (2) to 10 VDC signal.
