RP421012 12VDC DPDT Sealed Power Relay 8A 250VAC PCB Mount Relay

The RP421012 is a compact and reliable PCB-mounted power relay designed for industrial control systems, automation equipment, appliances, power management circuits, and electronic switching applications. Featuring a 12VDC coil and DPDT (Double Pole Double Throw) contact configuration, this relay delivers dependable switching performance for both AC and DC control systems.

Equipped with a 2 Form C (2C/O) contact arrangement, the RP421012 allows simultaneous switching of two independent circuits, providing flexibility for a wide range of control and automation applications. Its robust contact system is rated for up to 8A, making it suitable for switching motors, lighting circuits, power supplies, HVAC equipment, and other medium-power electrical loads.

The relay operates from a 12VDC coil and draws approximately 44.4mA of coil current, ensuring efficient operation while maintaining reliable switching performance. Designed as a non-latching relay, it returns to its default contact position when coil power is removed, making it ideal for conventional control circuits and safety-related applications.

Featuring a maximum switching voltage of 400VAC and a contact rating of 8A at 250VAC, the RP421012 is capable of handling a wide variety of electrical loads. The silver nickel (AgNi) contacts provide excellent conductivity, durability, and resistance to contact wear, ensuring long service life even under frequent switching conditions.

The sealed flux-protected housing safeguards internal components from contamination during PCB assembly and cleaning processes, improving long-term reliability and operational stability. Its PC pin termination style enables straightforward integration into printed circuit board designs, supporting efficient manufacturing and installation.

With a fast operating time of 9ms and release time of 3ms, the relay provides quick and responsive switching performance. It also offers a wide operating temperature range from -40 C to +70 C, making it suitable for demanding industrial and commercial environments.
