Siemens Building Technology 147-2000 Relay
The Siemens Building Technology 147-2000 Relay is a precision-engineered pneumatic positioning relay designed for demanding HVAC automation environments. This compact auxiliary device is essential for ensuring positive positioning of pneumatic valve actuators and damper actuators. By utilizing a low-bleed design, the 147-2000 minimizes air consumption while responding to input changes as small as 1/10 PSI. The unit allows for highly accurate field adjustments of both the start point (3 to 10 psig) and operating span (3 to 12 psig), making it a versatile solution for sequencing controlled devices. Built for industrial durability, it features a zinc body and electro-plated steel cover, maintaining reliable performance across an operating temperature range of 35°F to 160°F. For contractors overseeing multi-zone pneumatic systems, this relay is the standard for maintaining repeatability of stem position and high speed of response.
Key Benefits- Enhanced Control Precision: Facilitates positive positioning to overcome friction and high differential pressures in terminal equipment.
- Efficient Air Usage: Operates with a very low bleed rate (40 scim), reducing the total load on the pneumatic control system compressor.
- Field Adjustability: Simplified calibration of start point and span allows for precise actuator sequencing without replacing springs.
- High Air Capacity: Delivers 410 scim at a 2 psi differential, ensuring rapid actuator movement.
- Broad Compatibility: Compatible with Siemens No. 3, No. 4, and No. 6 damper actuators, as well as Flowrite valve assemblies.
