ABSTRACT:
A testing interface provides rapid, temporary connections to individual signal relays used in railroad signal systems when testing is required, and otherwise permits normal operation of railroad signal vital circuits through its connections. A connectivity block provides contacts that are used to isolate the relay from its application circuit and provide connectivity to the relay coils for testing when a connection paddle is inserted into the block. The interface allows fully automated or manual testing of installed relays without requiring removal from the relay rack.
