Input configuration
Indicates the compatible transistor type for the input device.
I/O delay time
Indicates the typical I/O delay time of the B7A. Use a combination of an Input and
an Output Link Terminal with the same I/O delay time.
Output configuration
Indicates the compatible transistor type for the output transistor.
Output current
Indicates the rated output current value of the B7A per point.
I/O delay time
Indicates the typical I/O delay time of the B7A. Use a combination of an Input and
an Output Link Terminal with the same I/O delay time.
