Question:

What is the export relay, what is the role

What is the export relay, what is the role

Answer:

The output relay is the relay used to make these two voltage levels work in different circuits. Relay (relay) is an electrical control device, when the input (excitation amount) changes to meet the specified requirements, in the electrical output circuit to control the amount of a predetermined step changes in an electrical appliances.

It has a control system (also known as the input circuit) and the control system (also known as the output circuit) between the interaction. Usually used in automated control circuits, it is actually a small current to control the operation of a large current "automatic switch". So in the circuit plays an automatic adjustment, security protection, conversion circuit and so on.

Export as the name suggests is the signal after processing the output interface ah, the general signal output voltage level is very low, can not withstand the normal control loop level, in order to make these two voltage levels in different circuits and the normal use of the relay.
