Timing Relay Dealers in Bangalore

Features Software based design Programmable time current characteristics Choice of four curves Selectable characteristic angle Programmable directional / Non-directional element Draw - out case Principle of Operation: The relay measures the line current from each of the phases and if it exceeds the set threshold, then relay extends a trip signal after an operating time. The relay's operating time is determined by selecting one of the four inverse time characteristics. The relay has facility to active / inhibit the high set protection feature. The relay output contacts are self reset . Relay operation without any fault current is determined by trip test facility.

MDDA Relay consists of a power supply unit, a timer unit and an attracted armature auxiliary relay. Resistor and Zener diode combination of the power supply unit provides low voltage stabilised DC supply to the static timer circuit. Non-linear resistors are used in the power supply unit for surge suppression. The timer unit consists of a timer circuit and a thumb wheel switch. The thumb wheel switch mounted on the name plate of the relay provides precise and high resolution time setting. The timer unit operates a reed relay which in turn energises an attracted armature auxiliary relay. This auxiliary relay is provided to achieve higher contact rating and flag indication, if required. MDDA can be provided either as a delay on pick up relay or as a delay on drop-off relay. A normally open contact is used for initiating time delay on pick up relay and output element gets energised after the set time delay. In the case of delay on drop off relay, the output element is normally energised and with the normally closed initiating contact opening out, the output elements gets de-energised after the set time delay.
