I/O Signals
The following table shows the I/O signals of the safety relay module.
* 1: The signal is always OFF regardless of the safety input status when the input of the main module
is OFF.
* 2: K0RB and K1RB indicate whether the actual safety relay contacts K0 and K1 are ON, respectively.
This allows a detection of welding of safety relay contact.
