The RY2S-UD-DC24V is a DPDT (Double Pole Double Throw) miniature relay with a 3A contact capacity and plug-in terminal configuration, specifically designed for DC coil applications. It features a 24 VDC coil voltage and includes an integrated diode to absorb back EMF generated when the coil is de-energized, which slightly extends the release time. The diode is rated for 1,000 V reverse withstand voltage and 1 A forward current. This relay is commonly used in industrial control systems, automation equipment, and general-purpose switching applications where reliable DC switching and protection against voltage spikes are required.
