What is BS EN 61811-1 - EM telecom relay test standard about?
Signal level switching is the forte of these relays. That is precisely where Telecom Electromechanical (EM) relays come into use.
BS EN 61811-1 applies to electromechanical telecom elementary relays. Relays according to this standard are provided for the operation in telecommunication applications. However, as electromechanical elementary relays, they are also suitable for particular industrial and other applications. BS EN 61811-1 determines the appropriate methods of test to be used in detail specifications derived from this specification and contains basic test schedules to be used in the preparation of such EM telecom relay.
Who is BS EN 61811-1 - EM telecom relay test standard for?
BS EN 61811-1 on EM telecom relay test standard is useful for:
- Manufacturers of communication devices
- Manufacturers of general-purpose and protection relays
- Product development / innovation / research teams
- Quality control teams
Why should you use BS EN 61811-1 - EM telecom relay test standard?
Typically double-pole, double-throw configurations with gold-flashed contacts, we have second, third, and fourth-generation telecom relay designs also. The relay is also an electromechanical switch used as a protection device and also as a controlling device for various circuits, equipment, and electrical networks in a power system. The electromechanical relay can be defined as an electrically operated switch that completes or interrupts a circuit by physical movement of electrical contacts into contact with each other.
BS EN 61811-1 provides you with guidelines on rated values, marking and documentation, preparation of blank details, and quality assessment procedures. In addition, BS EN 61811-1 also gives you details on test schedules and ordering information. Using BS EN 61811-1 guidelines, you can determine the appropriate methods of test to be used in detail specifications derived from this specification and contains basic test schedules to be used in the preparation of such EM telecom relay. BS EN 61811-1 guidelines enable you to manufacture and provide your customer with reliable and high-quality products.
