Johnson Controls' FA-VAV140-1 is part of the Metasys FA series and serves as a variable air volume controller. This equipment is suitable for use within a temperature range of 32°F to 122°F (0°C to 50°C). It features six analog inputs, allowing for flexible monitoring and control of environmental conditions. The analog inputs can handle voltage levels of either 0 to 2 volts DC or 0 to 10 volts DC, accommodating various sensor outputs.

For additional functionality, the module has four binary inputs that help in connecting simple on/off devices. It includes either zero or two analog outputs. When utilized, these outputs can deliver a voltage ranging from 0 to 10 VDC and support currents up to 10 mA.

The device also provides eight or six binary outputs that are rated at 24 VAC, using Triacs with a maximum current of 0.5 amperes to handle different actuator needs. Notably, the isolated N2 bus allows for reliable communication within a control system, enhancing the integration's efficiency.
