The 24 V AC coil picks the relay; the LED across the coil terminals gives a quick visual confirmation that the coil is energised, which saves a meter check during commissioning or fault-finding on a machine line. ## 8-pin octal base, socket mount This relay terminates to an 8-pin octal base — the standard pinout for a DPDT relay in this form factor. The socket mount means the relay plugs into a matching 8-pin socket (sold separately), so you can replace the relay without disturbing the panel wiring. That is a practical advantage for MRO spares: a failed relay swaps in seconds, not minutes. The socket mount also isolates the relay from panel vibration — the base is screwed or DIN-rail mounted, and the relay body clips into it. For a packaging line or conveyor control cabinet where relays cycle frequently, this mechanical decoupling extends the contact life by reducing arcing from mechanical shock.","metaTitle":"ABB 1SVR405621R0100 General Purpose Relay, DPDT, 10 A","metaDescription":"ABB CR-U series general purpose relay, 8-pin base, DPDT, 10 A contact rating, 24 V AC coil.
