URL relay bodies provide 2CO or 4CO switching in a transparent housing with a test lever. Choose the contact arrangement and exact coil voltage together: DLT models use DC coils and ALT models use AC coils. The selection tables below cover the available 26 combinations. Relay bodies and complete socket assemblies are separate products.

| Coil operating parameter | DC models | AC models |
|---|---|---|
| Pull-in voltage | ≤75% of rated voltage | ≤80% of rated voltage |
| Release voltage | ≥10% of rated voltage | ≥30% of rated voltage |
| Maximum operating voltage | 110% of rated voltage | |
| Operate time | <15ms | |
| Release time | <10ms | |
The maximum voltage, current and switching-capacity limits apply together. A 12A maximum current does not mean that every load can be switched at 12A at the maximum voltage. Select the relay for the actual load and check the matching socket's limits separately.
