High-quality Best-price Electric Non-Spring Return Actuators

Specifications

Description 

The M91xx Series includes M9108, M9116, M9124 and M9132 models. All of these direct-mount line of electric actuators operate on AC/DC 24 V 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 a 3/4in. (20 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 DC 0(2) to 10 V signal.

Features

• simple direct coupling reduces installation and commissioning time while improving reliability by eliminating damper linkages

• six torques: 70 to 560 lb·in (8 to 64 N·m) offer the most suitable choice for the application

• four control inputs meet the needs of most applications

• output position feedback provides simple closed-loop control with accurate position sensing

• electronic stall detection ensures higher reliability by deactivating the actuator motor when a stall condition is detected

• master/slave operation allows synchronized control for two actuators

• stacked for tandem applications

• zero and span adjustment (-HGx models) allows sequential operation of dampers from a single input signal of DC 0(2) to 10 V, DC 0(4) to 20 V, or DC 0(4) to 20 mA

• jumper-selectable rotation direction and manual gear release simplify installation, setup, and field adjustments

• NPT threaded housing provides easy connection for electrical fittings

• manual gear release simplifies damper/valve setup and commissioning
