GE 12HFA51A42H Multi-contact Auxiliary Relay

The GE 12HFA51A42H multi-contact auxiliary relay is an auxiliary relay with battery backup/latch technology, suitable for some control systems that need to remember the instantaneous state of power interruption.

In the event of a power interruption, the relay can use the lithium battery to preserve the contents of the image registers in RAM or save them in the EEPROM. During the first scan cycle after the PLC is re-energized, the relay will remain in the instantaneous state of power failure. This power failure memory function can be used in various control systems that need to remember the instantaneous state of power interruption.

In addition, the relay has multiple contacts and can be used to control a variety of different industrial equipment. It also has high reliability and stability, and can operate stably for a long time in harsh industrial environments.

In summary, the GE 12HFA51A42H multi-contact auxiliary relay is an auxiliary relay suitable for a variety of control systems that need to remember the instantaneous state of power interruptions.
