The RH2B-UCDC24V is a DPDT (double-pole double-throw) compact power relay manufactured by IDEC, featuring a 24 VDC coil with an integrated check button for manual operation verification. This miniature power relay delivers 10A contact capacity in a compact form factor that saves space in control panels and industrial equipment. The relay is rated for 10A at 30V DC resistive load and 7.5A at 30V DC general use, with a maximum contact voltage of 300V and 10A electrical rating. It is designed for blade terminal mounting and is compatible with standard DIN rail mount sockets (SH2B-05) and through-panel mount sockets (SH2B-51). Common applications include motor control, solenoid switching, and general-purpose industrial automation where reliable switching and manual test capability are required.
