General Purpose Relay MJN 319
Latching - DC
Note: 120% of nominal or greater (one second duration single pulse) unlatch voltage - - above this the relay latches again.
Maximum continuous voltage: 120% of nominal (one coil only).
■ Characteristics
Note: A latch pulse of 50 ms minimum at nominal voltage is recommended to insure positive latching.
