FA-VAV141-1

The FA-VAV141-1 model from Johnson Controls is specifically engineered as a Variable Air Volume Controller within the Metasys FA series. Its design allows it to manage air flow efficiently across a wide temperature span from 32 to 122°F (0 to 50°C), which is essential for maintaining optimal indoor conditions.

The unit provides six analog inputs, which can accept voltage signals ranging from 0 to 2 volts DC or 0 to 10 volts DC, allowing for versatile integration with various sensors and systems. In addition to the analog inputs, there are four binary inputs to accommodate straightforward control signals. This configuration is beneficial for comprehensive monitoring and control of HVAC functions.

For outputs, the controller can either provide two analog outputs or no outputs at all, with the analog voltage output reaching up to 10 VDC. It also features a current output capability of 10 mA, supporting external devices dependent on specific voltage feedback. The binary outputs comprise either six or eight outputs, each rated at 24 VAC Triacs, with maximum support of 0.5 amperes, facilitating connections to various devices and control components.

The FA-VAV141-1 also includes an isolated N2 bus, which enhances system integrity by minimizing interference during communication. This variable air volume controller is a vital component for modern HVAC solutions requiring precise air volume control and integration opportunities.
