Description
The ACI 122687 is a versatile duct enclosure transmitter designed for building automation and HVAC control applications where multiple output signal options are required. Engineered by Automation Components Inc. (ACI), this transmitter delivers three selectable output signals — 0-5 VDC, 0-10 VDC, and 4-20 mA — making it compatible with a wide range of building automation systems (BAS), DDC controllers, and data acquisition equipment.
The duct-mount enclosure is purpose-built for installation in air handling ducts, providing accurate and reliable signal transmission in demanding commercial and industrial HVAC environments. Its multi-output capability eliminates the need for separate transmitters when interfacing with different control platforms, simplifying installation and reducing overall system cost.
