relay contact sentence in Hindi

Examples

1. Double switching increases the cost and complexity of systems in which it is employed, for example by extra relay contacts and extra relays, so the technique is applied selectively where it can provide a cost-effective safety improvement.
2. The field inputs and outputs can either be continuously changing analog signals e . g . 4 ~ 20mA dc current loop or 2 state signals that switch either " on " or " off ", such as relay contacts or a semiconductor switch.
3. Consequently, for relays used to control inductive loads, we must specify the maximum current that may flow through the relay contacts when it actuates, the " make rating "; the continuous rating; and the " break rating ".
