COMPUTERIZED AUTOMATIC RELAY TEST SYSTEM

CVRT-S16 - Vasavi Electronics

CVRT-S8 & S16 are ideal for automatic testing of ELECTRO MECHANICAL AND READ RELAYS (only DC relays) both for static and dynamic characteristics. This system scans at one stroke, all the parameters of the relay as per definition of test procedure. The test sequence can be pre-programmed and stored in the disk. You can select the tests as per your requirement. Can include or exclude the test and you can have several options to match your test definitions. Semi skilled person can be engaged for actual testing, as he need not make any settings and need not interpret the readings. The system conducts the tests and gives PASS / FAIL indication on overall test results. If a printer is connected, each test result will be printed.
