Question

Which of the following options is/are used to maintain an energized state until another input signal is received?

Auxiliary relay.
Internal relay.
Latching circuit.
Counters.

Answer 1

Answer:

latching circuit is used yo maintain an energized state until another input signal is receivef

Answer 2

A latching circuit is used to maintain an energized state until another input signal is received.

• A latching circuit is a logic circuit having two stable states.
• Therefore it is referred to as a bistable multivibrator.
• The information in this circuit is retained using a feedback pathway which makes it a memory device.
• It can store information only when it is powered on.
• When the circuit is enabled, the latch will begin to change the stored information according to the input.
• It can continuously sample the inputs as long as it is in the enable mode.
