Honeywell Stryker, 21 IO

The Honeywell Stryker 21 IO is a configurable Variable Air Volume (VAV) controller. It comprises of 6 Universal Inputs (UI), 4 Digital Inputs (DI), 3 Analog Outputs (AO) and 8 Relay Outputs (RO). Integrating seamlessly on the Echelon LonWorks network, the controller is capable of standalone operation but is also fully operable using LONWorks bus network communications. The Stryker 21 IO facilitates the use of Sylk-enabled sensors via its Sylk Bus, coupled with a Real-Time Clock.

Notably, the device is meticulously designed for user-friendly application and is field configurable for control, input, and output functions using NIAGARA FRAMEWORK® software. It integrates advanced built-in zone control functions, including a Scheduler and a remote wall module interface. Enhancing the overall user experience, it provides easy accessibility to air flow sensor inputs, facilitated by a Microbridge Air Flow Sensor incorporating a dual integral restrictor design.

Technical advancements and robustness are apparent in the details. The controller housing and actuator carry a UL Plenum Rating, demonstrating their suitability and safety for use in air handling spaces. The power voltage is rated for 24 VAC but can accommodate a valid range of 20 to 30 VAC. All controller wiring connections are configured into removable terminal blocks for a simplified installation and replacement process.

The Stryker 21 IO also operates within a temperature range of 0 to 50°C (32 to 122°F). It aligns with compliance standards and holds approvals such as UL/cUL (E87741) listed under UL916 with Plenum Rating, CSA (LR95329-3) listing, and meets FCC Part 15, Subpart B, Class B for radiated emissions requirements.

The device is programmable via Niagara Tools and operates on a FTT-10A LON communication network. It's built for versatile applications, including AHUs, and supports DIN Rail mounting. The advanced functionality and versatile features make the Stryker 21 IO a powerful addition to Honeywell's range of industrial automation and control systems.
