When the power supply is interrupted the time period starts and, at the end of the set time period, the relay releases. If power supply is reapplied before the relay releases the time is reset and the relay remains ON. Note: DBB51 shoud not be oper- ated by pulses shorter than 200 ms. For these puroposes the relay DMB51, operated by external contact function, should be used. Time setting Knob adjustable on absolute scale.
