2KL-2B-148
2PDT magnetically latching relay
2KL-2B-148 is a hermetically sealed, magnetically latching 2PDT relay with separate DC set and reset coils and 10 pin terminals. Contacts are rated up to 2 A resistive at 28 Vdc, with 100,000 operations electrical life. Coil: 48 Vdc, 3800 Ω ±15% at 25°C; maximum coil voltage 60 Vdc. Mounting: B — Side flanges. The relay retains its last state after coil power is removed; apply a pulse of at least 15 ms and observe the wiring-diagram polarity.
