Johnson Controls Y65G13-0 Transformer

For high-reliability HVACR control circuits requiring precise 24V to 24V isolation, the Johnson Controls Y65G13-0 Transformer is a critical component for protecting sensitive electronics from ground loops and electrical noise. This 40VA Class 2 transformer features a split-bobbin design that ensures superior primary-to-secondary isolation, maintaining signal integrity in complex building automation systems and digital controllers. Designed for 60 Hz operation, the Y65G13-0 includes inherent overload protection to prevent catastrophic failure during circuit faults. The unit is built for versatile installation with a foot mount and single hub configuration, utilizing 8-inch primary and 30-inch secondary color-coded lead wires for rapid field identification. As a UL/cUL listed component, it meets UL 1585 and CSA C22.2 No. 66 standards, making it the industry-standard choice for gas controls, motor actuators, and ignition systems that demand steady voltage regulation without direct electrical contact between circuits.

• Enhanced Signal Integrity: The 1:1 isolation transformer ratio prevents ground loops, protecting microprocessors in digital control systems.
• Inherent Protection: Internal safety mechanisms handle overcurrent conditions without the need for external fuses on the transformer body.
• Flexible Installation: Foot mount design and color-coded leads (8" primary, 30" secondary) streamline replacement in tight control cabinets.
• Robust Compliance: Fully meets UL Class 2 specifications for safe power distribution in residential and commercial HVACR applications.

What is the purpose of a 24V to 24V isolation transformer?
It provides galvanic isolation between two 24VAC circuits, which prevents electrical noise and ground loops from disrupting sensitive HVAC controllers or sensors.

Can the Y65G13-0 be mounted in any orientation?
Yes, the foot mount configuration allows for secure mounting on various surfaces within a NEMA enclosure or directly onto the equipment chassis.

Will this transformer handle 24V motor actuators?
As long as the total load does not exceed 40VA, this transformer is specifically engineered to drive actuators, relays, and staging controls.
