Description
The Siemens GCA136.1P is a heavy-duty, plenum-rated spring-return damper actuator engineered for reliable performance in commercial HVAC and building automation applications. Designed to operate on a 24V control signal, this actuator delivers 142 in-lb of torque, making it well-suited for medium to large damper assemblies in air handling units, VAV systems, and ventilation control applications.
Key Features
- 24V AC/DC control voltage for broad system compatibility
- 3-position control for precise open/closed/intermediate damper positioning
- 142 in-lb torque output for dependable damper authority on larger assemblies
- Spring-return (SR) fail-safe operation — damper returns to a safe position on power loss
- Two (2) built-in auxiliary switches for end-position feedback and system interlocking
- Plenum-rated construction meets requirements for installation in air plenums without conduit
Application
The GCA136.1P is ideal for use in commercial building automation systems where fail-safe damper control is critical. The spring-return mechanism ensures the damper moves to a predetermined safe position during a power interruption, protecting building occupants and equipment. The dual auxiliary switches provide end-position feedback signals to building automation controllers, enabling system status monitoring and interlock sequencing.
