When an interlock is required for safety, a separate circuit should be provided that meets the
requirements of the application to reliably protect the operator from exposed voltages. The
digital I/O port of the 3761 is not suitable for control of safety circuits and should not be used
to control a safety interlock. Bypassing the interlock can result in personal injury or death
from electric shock.
