DPDT Relay 24V DC 57DP-24-2C2 (OEN)

Description

The DPDT Relay 24V DC 57DP-24-2C2 (OEN) is a highly reliable miniature electromechanical power relay designed for seamless integration into printed circuit boards (PCBs). Manufactured by OEN, a trusted name in industrial switching components, this relay features a Double Pole Double Throw (DPDT / 2 Form C) configuration. This allows you to safely control and isolate two separate electrical circuits simultaneously using a single 24V DC control signal.

Available at Tomson Electronics, the 57DP-24-2C2 is built with high-quality silver alloy contacts that ensure excellent conductivity and long-lasting mechanical endurance. It is widely utilized in industrial automation, process control panels, and custom power supplies where reliable electrical isolation between the low-voltage control side and the higher-voltage load side is critical. Its compact, dust-proof casing ensures space-saving installation without compromising on switching power.

Frequently Asked Questions (FAQ)

Q: What does "2 Form C" mean?
A: "2 Form C" is the industry-standard terminology for a DPDT (Double Pole Double Throw) switch or relay. It means the relay contains two separate switches (poles), and each switch has a Normally Open (NO) and a Normally Closed (NC) contact (double throw).

Q: Can I drive this relay directly from an Arduino or ESP32 pin?
A: No. Microcontrollers typically output 3.3V or 5V at very low currents. Because this relay requires a 24V DC supply to energize the coil, you must use a relay driver circuit (such as a transistor or a ULN2003 IC) and a separate 24V power source to switch the coil.

Q: Is this relay suitable for switching high-current AC mains?
A: The 57DP-24-2C2 is primarily rated for low-to-medium power and signal switching (typically around 2A). If you need to switch heavy loads like heaters, air conditioners, or large AC motors, you should use a higher-rated power relay or a contactor.
