3503E TRICONEX
Models 3502E, 3503E, and 3505E can self test to detect stuck conditions where the circuit cannot determine whether a point has entered a closed state. Since most safety systems are equipped with a power off trip function, the ability to detect the OFF point is an important function. To test a stuck input, a switch in the input circuit is turned off to allow the optical isolation circuit to read the zero input (OFF). When the test runs, the final data readings are frozen in the I/O communication processor.
