Product description
The Siemens 322-1BH01-0AA0 is a 24V DC latching relay with a 1 Normally Open (NO) and 1 Normally Closed (NC) contact set. Latching relays maintain their state after the coil is de-energized, requiring a second pulse to change state.
This relay is valuable in applications where memory is needed, such as maintaining a signal state without continuous power. It's used in automation systems for control sequences, safety interlocks, and power management.
Stanlo Automation, a veteran-owned supplier of surplus industrial automation parts, offers this Siemens latching relay. We help you source specialized components for your automation needs.

Frequently asked questions
How does a Siemens 322-1BH01-0AA0 latching relay operate?
A latching relay like the Siemens 322-1BH01-0AA0 maintains its contact position after the coil is de-energized. A second pulse to the coil is required to change the contacts to their opposite state, effectively providing memory.
