ELECTRIC MOTOR ACTUATOR; 70 IN-LB/8NM; 24 VAC/VDC; ON/OFF - FLOATING; 30 SEC

Description

The M91xx Series includes M9116, M9124, and M9132 models. All of these direct-mount 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 3/4 in. (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
