MDDA
Definite Time Lag Relay
Description
Applications
Type 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.
Type MDDA is a Definite Time Lag that can be used for
applications where an accurate and consistent time-delay
operation is 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.
