Figure 12 - 5069-IB8S or 5069-IB8SK Test Pulse in a Cycle
On the 5069-IB8S or 5069-IB8SK module, the test pulse width (X) is less than
700 μs; the test pulse period (Y) is less than 100 ms.
When the external input contact is closed, a test pulse is output from the test
output terminal to diagnose the field wiring and input circuitry. By using this
function, short-circuits between inputs and 24V power, and between input
signal lines can be detected.
