Siemens Building Technology S55180-A157 Control
The Siemens Building Technology S55180-A157 is a heavy-duty SSE Series electronic actuator engineered for precise 0-10V modulation in commercial HVAC systems. This 24VAC non-spring return (NSR) unit is designed for normally closed (NC) operation, making it a reliable solution for modulating airflow or hydronic flow when paired with compatible 599 Series zone valves. With a 1/10-inch (2.5 mm) stroke and a fast 12.5-second positioning time, it provides the rapid response required for advanced building automation systems (BMS) and air handling unit (AHU) balancing.
Built for the rigors of mechanical rooms, the Siemens S55180-A157 features a linear actuation style and a low 3 VA power consumption profile. The NEMA 2 rated enclosure supports plenum installations, while the integrated LED visual position indicator allows for immediate diagnostic verification in the field. This model replaces the legacy SSA61U, offering technicians a direct-coupled installation process that requires no specialized tools for mounting. Its fail-in-place design ensures stable positioning during standard operations, maintaining system equilibrium across ventilation networks.
Key Benefits for Contractors:
- Precise 0-10 Vdc Signal: Ensures accurate HVAC damper control and valve positioning for optimized thermal comfort.
- Tool-Free Installation: Direct-coupled universal bonnet design allows for quick field mounting on Siemens 599 Series valves.
- Plenum Rated: UL listed for use in environmental air spaces, meeting strict commercial building codes.
- Manual Override: Features a 3mm hex manual adjustment for commissioning or emergency positioning without power.
- BMS Integration: Seamlessly communicates with standard 24V control loops and Siemens building technology platforms.
Common Questions:
Is this actuator compatible with other brands?
While designed for Siemens 599 Series zone valves, it follows industry-standard 0-10V modulation protocols; however, check stroke compatibility (2.5mm) before attempting field retrofits.
Does this unit return to start on power loss?
No, this is a non-spring return (NSR) actuator that will fail-in-place or remain at its last position depending on the specific application setup.
How do I verify the current position?
The unit includes a built-in LED indicator that provides visual feedback on the current stem position and calibration status.
