Siemens Building Technology ASC77.2U Kit
The Siemens ASC77.2U is a field-installable external dual auxiliary switch kit designed for seamless integration with GIB, GBB, and GCA series OpenAir actuators. Engineered for precision positioning, this double auxiliary switch allows technicians to monitor actuator stroke and signal external equipment at predetermined rotation angles. With a heavy-duty 24V to 250V AC/DC switching capacity, the ASC77.2U is essential for interlocking fans, dampers, or secondary valve controllers in complex BAS (Building Automation Systems). This Siemens actuator accessory features two independent, adjustable SPDT (Single Pole Double Throw) switches housed in a durable NEMA 2 rated enclosure, ensuring reliable feedback for damper actuator end switches. Proper calibration of the auxiliary switch kit ensures optimal system sequencing and safety logic in commercial HVACR applications.
Key Benefits:
- Universal Compatibility: Specifically designed for GCA actuators and GIB/GBB series high-torque motors.
- Adjustable Switching Points: Dual SPDT contacts can be set to any position between 0 and 90 degrees for precise signaling.
- Simplified Field Mounting: Direct-mount design attaches to the actuator housing without complex linkages.
- High Electrical Versatility: Handles loads ranging from low-voltage control signals to line-voltage equipment interlocking.
Common Questions:
How do I set the switching point on the ASC77.2U?
The switching position is adjusted by rotating the setting scales via the access ports on the housing. Ensure the actuator is at the desired trip point before tightening the adjustment mechanism.
Can this kit be used on non-Siemens actuators?
No, the ASC77.2U is a proprietary Siemens Building Technology component designed exclusively for the mechanical footprint of the OpenAir series.
What is the maximum current rating for these switches?
These switches are typically rated for 6A inductive/12A resistive, providing robust performance for most HVAC control pilot duties.
