Johnson Controls Y350R-1 Module

The Johnson Controls Y350R-1 is a core component for System 350 Modular Control Systems, functioning as a high-reliability 24 VAC power supply module. This Class 2 power module is engineered to convert 120 or 240 VAC primary power into a stable, rectified 24 VAC output to drive stage, display, and electronic temperature control modules. Built for longevity in demanding environments, it features a heavy-duty NEMA 1 high-impact plastic enclosure and supports a wide operating temperature range from -30?F to 150?F. The modular design utilizes a 5-pin plug-in connector system and 35 mm DIN rail mounting, which eliminates the need for extensive interconnect wiring between components. For technicians managing multi-stage HVACR setups, the Y350R-1 reduces inventory overhead by handling dual-voltage requirements in a single footprint, providing 40 VA of power to sustain multiple System 350 add-on modules without voltage drop or signal interference.

Key Benefits for the Contractor:

• Dual-Voltage Versatility: Field-selectable input for both 120 and 240 VAC applications, simplifying truck stock.
• Standardized Mounting: Native support for 35 mm DIN rail or surface mounting via rear key-slot holes for flexible installation.
• Reduced Installation Labor: Modular 5-pin plug connections allow for instant expansion without point-to-point field wiring between stages.
• Robust Protection: Housed in a NEMA 1 enclosure to protect internal electronics against shop environments and debris.
• High Capacity: Sufficient 40 VA rating to power complex modular control systems including multiple S350 stage and D350 display modules.

Common Technical Questions:

Is the output of the Y350R-1 regulated?
The module provides a rectified 24 VAC output (approx. 16-38 VDC measured at the terminals) specifically tailored for the power requirements of System 350 digital and analog modules.

How many stage modules can one Y350R-1 power?
Depending on the specific control module used (such as the A350A), a single power module can typically support up to 9 S350A stage modules or a combination of stage and display modules, provided the total draw does not exceed the VA rating.

Can this be used with non-System 350 equipment?
The Y350R-1 is specifically designed with the proprietary 5-pin connector interface for the System 350 family and is intended for use within those modular architectures.
