The burden of the relay input is typically very small comparing to external stabilizing resistance and can in most applications be neglected. Remark: In the past the relays used constant operating current (e.g. 20 mA or 100 mA) and the setting was adjusted by settable resistors (mounted internally within the relay). different process steps. When defining a test procedure 4 and before choosing a test method or tool, the objective should always be made clear e.g. testing for relay failures or logic errors. As there will be no 100% coverage for every possible cause for a misoperation the decision for a tool always has to balance cost & benefit. epoc Blood Analysis System The epoc system is a handheld, wireless solution to enable comprehensive blood analysis testing at the patient’s side on a single room temperature test card, with results in less than a minute. Checking the operation of a fan relay on your vehicle is an easy procedure. Just keep in mind that many modern cars use electronic relays.
