Information About MS40-7043-501
The MS40-7043-501 is part of the Schneider Electric DuraDrive MS40-7043 actuator series. Its direct-mount construction connects the output mechanism to a compatible shaft. A reversing switch selects direct-acting or reverse-acting control, while a voltage feedback output indicates actuator position. The built-in SPDT auxiliary switch has an adjustable operating point within the actuator’s travel range.
Key Features:
- Proportional Control: Accepts a 2–10 VDC signal for modulating damper or valve positioning.
- Current Input Compatibility: Supports 4–20 mA control with a field-supplied 500-ohm resistor.
- Rated Output Torque: Provides 35 lb-in (4 N·m) for the connected mechanism.
- Mechanical Spring Return: Returns the actuator when supply power is removed.
- Auxiliary Switch: Includes one SPDT switch adjustable from 0° to 95°.
- Position Feedback: Supplies a 2–10 VDC output for position monitoring.
- Direct Mounting: Couples to a compatible shaft for mechanical operation.
- Environmental Protection: Features a NEMA 2 / IP54 enclosure.
The MS40-7043-501 delivers the reliability and precision required for proportional positioning and spring-return operation in compatible HVAC systems.
