MAGNETIC INTERFERENCE
relays inserted close proximity, pickup dropout voltages will affected magnetic flux produced when coils energized. general, worst-case magnetic interaction conditions pull-in voltage matrix exist when relay fields have same polarity fields from adjacent relays (See figure). direction parameter shift determined whether stray flux aids bucks flux produced coil relay under consideration. calculate change pull-in voltage dropout voltage, multiply percent change shown relay's nominal voltage. example, percent change pull-in voltage nominal relay, pull-in voltage will increase volts.
