Relay testing device and methods for testing relays

摘要

A testing device for a relay includes an enclosure for containing a circuit that includes at least one electrical socket adapted for selective engagement with a connector of the relay, a power source, a testing indicator LED adapted to convey a testing results indication, a power switch, and a testing IC adapted to run a series of tests on the relay when the relay is engaged with the at least one socket. In use, with the connector of the relay engaged with the at least one socket, power may be applied to the circuit such that the testing IC runs the series of tests on the relay by alternately activating and deactivating the coil power lines and measuring the resulting state of the armature line, the normally open signal line, and if available the normally closed signal line of the relay.
