![Page 7: Kamlesh meena tarinig ppt instrumentation limited](https://reader036.vdocument.in/reader036/viewer/2022081422/55845882d8b42a6a6d8b549d/html5/thumbnails/7.jpg)
Off Line UPS
In offline UPS input is directly connected to output.
Inverter is not used in this type of UPS.
Output will be in square form because input is directly connected to output.

What is a relay
A relay is a multi switch device with multiple mating contact pairs.
The relay are two contact pairs-1.font contact pairs= front contact pairs are normally open.2.Back contact pairs= The back contact pairs are normally close.

LINE RELAY
• This type of relay is used for classification of line.
• There are two signals Red and Green.
a) Red signal indicates that the line is busy.b) The green signal indicates that line is clear.
