Automation Components Inc (ACI) 127211 Valve

The ACI 127211, also identified as the PXP2.3GFS, is a high-performance pneumatic transducer designed for precise HVAC pressure control. This dual-valve electronic-to-pneumatic transducer converts a 0-5 VDC input signal into a linear 0-15 PSI pneumatic output, making it an essential component for interfacing electronic controllers with pneumatic actuators. Engineered by Automation Components Inc (ACI), the 127211 features a gauge port and a failsafe manual override, ensuring reliable performance in complex building automation systems. Its dual-valve design optimizes air consumption while providing rapid response times and superior accuracy for pressure-to-current conversion applications. Whether you are managing dampers, valves, or other pneumatic peripherals, this 0-5VDC to 0-15 PSI transducer offers a rugged solution for maintaining stable environmental conditions within commercial and industrial facilities.

• High Precision Control: Delivers accurate 0-15 PSI output with minimal hysteresis for refined pneumatic signal conversion.
• Dual Valve Efficiency: Enhances air flow management and reduces bleed rates compared to single-valve alternatives.
• Universal Compatibility: Serves as a direct replacement for the PXP2.3GFS, ensuring easy integration into existing BACnet or analog control loops.
• Field Reliability: Includes an integrated pressure gauge for real-time monitoring and troubleshooting.

How do I calibrate the ACI 127211 for a 0-5VDC signal?
The unit is factory-calibrated for a 0 to 5 VDC input to provide a 0 to 15 PSI output. Fine-tuning can be performed via the onboard zero and span potentiometers to account for specific site requirements.

Can the ACI 127211 be used in failsafe applications?
Yes, the dual-valve architecture is designed to maintain or bleed pressure based on your sequence of operations, and the manual override allows for emergency HVAC pneumatic troubleshooting.

What is the maximum supply pressure for this transducer?
The ACI 127211 typically requires a filtered, dry air supply, with a maximum recommended supply pressure of 30 PSI to ensure the longevity of the pneumatic control components.
