About this product
A fully sealed 24 V DC single-pole double-throw (SPDT) relay with five pins, rated up to 10 A on its contacts. It lets a low-voltage control circuit switch higher-voltage or higher-current loads, and is commonly driven from a microcontroller output through a transistor.

Frequently asked questions
How should I drive this 24 V relay from a microcontroller?
Do not connect the coil directly to a microcontroller pin. Switch the coil with a transistor or MOSFET from a 24 V supply, and add a flyback diode across the coil.
What is the difference between this relay and the 12 V version?
The 24 V version needs a 24 V coil supply and has a minimum switching voltage of 22 V, compared with 11 V for the 12 V version. Both are SPDT, sealed, 5-pin relays, but the coil voltage must match your control supply.
