The Allen-Bradley Model 700-HN204 is a versatile and reliable single-pole, double-throw (SPDT) contact relay from Rockwell Automation. This compact, 1-inch mounting format, AC contactor offers robust performance and reliability, making it an ideal choice for various applications within automated industries.
The 700-HN204 relay is designed for use with nominal 480V, 600V, and 575V AC power sources. Its vast electrical specifications encompass a current carrying capacity of 10 Amps at 480V and an interchangeable AC contact voltage range of 277/480V to 600V AC. With a contact voltage rating of up to 120V AC and a coil voltage of 120V AC, this relay allows for seamless integration into various machine controls and electrical systems.
Equipped with a silver-alloy contact material, the Allen-Bradley 700-HN204 relay ensures long contact life and reliable performance even under heavy usage. Furthermore, the unit features a 10A NEMA size 5 contact frame, which accepts standard contactors and overload relays. This capability enables the user to have more flexibility in designing different control schemes with ease.
For composite duty ratings, the model 700-HN204 can withstand up to 40,000 contact makes and 20,000 contact breaks per hour. The relay comes with a gold-plated, non-shunted coil termination that accepts a standard screw terminal for simplified wiring and easy field assembly. The coil is also manually resettable, allowing users to reset the relay manually when needed.
Additionally, the 700-HN204 relay has a mechanical latching contact operation to ensure that contacts remain connected or disconnected even in the absence of power. It also comes with an integral contact spring reasonable thrust design, which helps maintain contact integrity and reduces unwanted wear-and-tear.
To provide optimal operating conditions and safeguard against electrical hazards, the Allen-Bradley Model 700-HN204 relay is mechanically interlocked between its contact and coil circuitry. This feature ensures that the contacts will not operate unless the coil is energized and vice versa, thereby promoting increased safety and system reliability.
