Siemens-Talon 550-430PA Actuator
The Siemens-Talon 550-430PA is a professional-grade BACnet MS/TP actuator designed for high-performance direct digital control (DDC) in pressure-independent VAV terminal box applications. As a veteran technician knows, the integration of a GDE131 non-spring return rotary electronic damper actuator with an onboard ATEC controller significantly reduces installation footprint and wiring complexity. This unit delivers a dependable 44 lb-in torque (5 Nm), making it the standard choice for precise airflow modulation in cooling, heating, or reheat sequences.
Operating on a 24 VAC power supply, this Siemens Talon actuator handles 5 VA base consumption with an additional capacity for 4 Triac digital outputs (12 VA each). It features an integrated differential pressure sensor for accurate CFM measurement and PID control algorithms that maintain tight setpoint stability. The 550-430PA resides seamlessly on any BACnet network, utilizing EEPROM for data storage to ensure all parameters are retained during power cycles without the need for battery backups. Its rugged construction supports a wide ambient operating range of 32°F to 122°F, ensuring reliable field performance in demanding plenum environments.
Key Benefits- Seamless Integration: Combines a VAV controller and 44 lb-in actuator into a single assembly for faster field mounting and reduced inventory.
- Open Protocol Communication: Native BACnet MS/TP compatibility allows for effortless networking with any standard Building Automation System (BAS).
- Maintenance-Free Reliability: Features a brushless motor and direct-coupled mounting, eliminating wear-prone linkages and manual calibration requirements.
- Enhanced Control Precision: Onboard 10K Ohm thermistor input and Triac outputs enable locally managed reheat and fan control sequences.
- Field Efficiency: Includes a quick-connect RJ-11 jack for room sensors and removable terminal blocks for streamlined communication and power wiring.
What damper shaft sizes are compatible with the 550-430PA?
This actuator supports standard round shafts from 3/8" to 5/8" diameter and square shafts from 1/4" to 1/2". A 3/8-inch adapter is typically included for smaller shaft applications.
Can this unit operate in standalone mode?
Yes, the Siemens-Talon 550-430PA can function as a standalone DDC controller or be networked via a Floor Level Network (FLN) trunk for centralized management.
Does this actuator require an external pressure transducer for VAV control?
No, it features a built-in differential pressure sensor that connects directly to the VAV box's velocity sensing elements to convert readings into actual airflow data.
