The M9203-xxx-2(Z) Series Electric Spring Return

Actuators provide control of dampers in Heating,

Ventilating, and Air Conditioning (HVAC) systems. All

actuators in this series provide 27 lb·in (3 N·m) rated

torque. A mechanical spring return system provides

rated torque with or without power applied to the

actuator. The series includes the following control

options:

• On/Off, 24 V, 85 to 264 VAC power

• On/Off and Floating Point, 24 V power

• Proportional, 24 V power, for 0(2) to 10 VDC or

0(4) to 20 mA Control Signal

These actuators are configured for direct mounting and

do not require a damper linkage. Actuators can be

mounted directly to a damper shaft from 1/4 to 1/2 in.

(6 to 12 mm) diameter with a universal clamp. An

accessory crankarm and remote mounting kit are

available for applications where the actuator cannot be

direct-coupled to the damper shaft. An optional line

voltage auxiliary switch indicates an end-stop position

or performs switching functions within the selected

rotation range.

Table 1: Features and Benefits (Part 1 of 2)

Features Benefits

27 lb·in (3 N·m) Rated Torque Provides high torque in a compact package size to expand the range of damper

applications in HVAC systems.

Direct-Coupled Design Requires no crankarm or linkage and is capable of direct mounting to a shaft up to

1/2 in. (12 mm) diameter and centered on a 1/2 in. (12 mm) shaft.

Reversible Mounting Provides either clockwise or counterclockwise operation.

Electronic Stall Detection Protects from overload at all angles of rotation. Power consumption is reduced in

holding mode. The actuator may be stalled anywhere in its rotation range without

the need for mechanical end switches.

Double-Insulated Construction Eliminates need for electrical ground connection for regulatory agency compliance.

Microprocessor-controlled

Brushless DC Motor

(-AGx and -GGx types)

Provides constant runtime independent of torque.

External Mode Selection Switch

(-AGx and -GGx types)

Permits control logic reversal for Floating Control (-AGx types). Permits calibration,

input signal range selection, and control logic reversal for Proportional Control

(-GGx types).

Integral Cables with Colored and

Numbered Conductors

Simplify installation and field wiring.

Integral 1/2 in. (13 mm) Threaded

Conduit Connector(s)

Simplify installation and field wiring.

Table 1: Features and Benefits (Part 2 of 2) Features Benefits Optional Integrated Auxiliary Switch Provides one integrated, line-voltage-capable Single-Pole, Double-Throw (SPDT) switch with continuously adjustable switch point. Facilitates safety interfacing or signaling. Plenum Rated Models Enable use in other environmental air spaces (plenums) in accordance with section 300.22(C) of the National Electric Code.

The M9203-AGA-2 and M9203-AGA-2Z actuators include plenum-rated cables and are specially configured for installation in spaces used for environmental air-handling purposes other than ducts and plenums as specified in National Fire Protection Association (NFPA) 70: National Electrical Code section 300.22(C), Other Space Used for Environmental Air. The space over a hung ceiling, when used for environmental air handling purposes, is an example of the type of space for which these actuators are configured.
