Binary inputs and outputs (BIOs) play an important role in the overall operation of protection relays, to include various control and interlocking schemes, as well as generating alarm and trip signals to the circuit breaker. In addition to secondary injection testing of protection functions, it is advisable to check the health of other important hardware such as BIOs. The incorrect operation of a control scheme may result in process or revenue loss, as well as safety threats to personnel and damage to the equipment. BIOs can be checked at the primary design stage and during routine maintenance and testing to ensure the accuracy of the applied logic.
ABB BIO testers are intended to facilitate the testing of BIOs and provide the following benefits:
- Reduced time for testing the configuration at all life cycle stages (design, commissioning, periodic maintenance, modifications, and replacements)
- Reduced risk for configuration errors
- Increased operational safety
- Ease of use and on-site installation due to compact size
Relion® BIO-Testers for easy simulation and testing
Relion® BIO-Testers are intended for testing the binary inputs and outputs of Relion protection relays. These easy-to-use compact testers enable simulation of the protection and control scheme operation. The testers can also be used for troubleshooting during the design of the application configuration and for routine maintenance and testing.
