M9203-BGA-2 Johnson Controls Actuator

Overview

The Johnson Controls M9203-BGA-2 is a reliable, two-position (On/Off), spring-return electric actuator designed to provide direct-mount control of dampers and valves in commercial and light industrial HVAC systems. Operating on both 24 VAC and 24 VDC power supplies, this bidirectional actuator eliminates the need for external linkage hardware by mounting directly onto standard damper shafts, saving installation time and reducing system complexity.

Features

• Direct-Coupled Design: Mounts directly to round or square damper shafts without requiring a separate external linkage.
• Mechanical Spring Return: Automatically drives the actuator back to its designated fail-safe position during a power interruption.
• Dual-Voltage Operation: Integrates seamlessly with building automation systems using either 24 VAC or 24 VDC inputs.
• Robust Enclosure: Built with a NEMA 2 (IP54) rated housing and electronic stall detection to safeguard the motor against electrical overload.
• Simplified Wiring: Comes pre-equipped with a 48-inch appliance cable and 1/2-inch conduit connectors for code-compliant installation.

Specifications

• Supply Voltage: 24 VAC (at 50/60 Hz) or 24 VDC
• Torque Output: 27 lb-in (3 N·m) running and spring return torque
• Control Signal: Two-Position (On/Off)
• Rotation Stroke: 95 degrees
• Power-On Running Time: Less than 75 seconds
• Spring Return Time: Less than 25 seconds
• Enclosure Rating: NEMA 2 (IP54)
• Operating Temperature: -40° to 140°F (-40° to 60°C)

Applications

The M9203-BGA-2 is ideal for commercial building automation and HVAC environments where simple open/close control is needed. It is frequently employed on air handling units, variable air volume (VAV) terminal boxes, zone dampers, and VG1000 Series ball valve assemblies to manage ventilation, airflow, and localized climate control zones.
