Honeywell Optimizer VAV Controller, 12 IO - VAA-VA75I24NMC

The Optimizer VAV Controller, with 12 IO, is a programmable control system featuring seven Universal Input/Output (UIO) interfaces, five Solid State Relays (SSR) for Digital Output (DO), and two RJ-45 ports serving as an essential gateway for BACnet IP communications. It includes an RS-485 port, facilitating seamless integration with Modbus RTU. The controller is distinguished by its integrated 44 in-lb actuator and position feedback.

This model flaunts a field-replaceable differential pressure sensor, which measures up to 500 Pa with an accuracy of +/- 3% of the full range, ensuring accurate control and consistent system performance. The VAV Controller also incorporates a Sylk two-wire polarity-insensitive interface, making it seamlessly connectible to Honeywell Sylk wall modules without requiring any hardware Input/Output (I/O).

To further compliment the user experience, the Optimizer VAV controller is supplemented with several engineering tools. These include a function block library and sample application templates, ensuring a uniform experience from room controllers, plant controllers over to supervisory systems. This feature also assists users in adhering to best practices and achieving streamlined control.
