X-302878 ALLEN BRADLEY Relay

Review ALLEN BRADLEY Relay 120v #109g144 Co

The Allen-Bradley Model X302878 is a versatile 120V AC, Form C, SPDT (Single Pole Double Throw) relay from Rockwell Automation's Allen-Bradley product line. This relay is an essential component in various control systems, providing reliable switching functions for electrical circuits.

The X302878 features a coil voltage rating of 120V AC, with a maximum operating current of 109 mA. It is suitable for applications requiring low-power switching functions. The contacts of this relay are rated for a contact voltage of 120V AC, making it suitable for use with standard AC power sources.

The contact rating for this Allen-Bradley relay is SPDT, meaning it has one common terminal and two normally open (NO) contacts. When the coil is de-energized, both NO contacts are open, and no current flows between the contacts. When the coil is energized, the contacts close, allowing current to flow between the contacts' terminals.

This relay comes with a built-in coil and offers a contact rating of 109g144. The contact rating represents the maximum continuous current capacity of the contacts and the number of contact interruptions the contacts can handle before requiring maintenance. In this case, the X302878 can handle a maximum of 109 amps (g) at 144 interruptions (144 cycles) per hour.

The Allen-Bradley X302878 relay is designed for durability and long-term reliability. It features a copper-alloy contact material that ensures excellent contact resistance and a stable contact pressure, ensuring reliable switching functions even under heavy load conditions. The relay's contacts are also gold-plated, minimizing contact wear and providing excellent conductivity.

This relay is suitable for use in various industrial applications, including HVAC systems, machine control, and process control systems. It is designed to meet the demanding requirements of industrial environments and can operate in temperatures ranging from -25 C to 65 C, ensuring reliable performance in a wide range of operating conditions.

The Allen-Bradley X302878 relay is housed in a compact and robust plastic enclosure that measures 3.62 inches (92 mm) in length, 2.4 inches (61.5 mm) in width, and 1.2 inches (30.5 mm) in height. Its compact size makes it easy to install and integrate into various control systems. The relay also features a clear and visible coil status indicator, making it easy to monitor the status of the coil and the relay's switching functions.

In summary, the Allen-Bradley X302878 is a versatile and reliable 120V AC, Form C, SPDT relay suitable for various industrial applications. It features a compact design, robust construction, and excellent contact performance, making it an essential component for reliable switching functions in industrial control systems.
