The F-8040 features 32 digital input (sink/source) channels. Either sink- or source-type input can be
selected via different wiring. The F-8040 can determine binary input from a DC voltage source. The digital
input channels also offer LED indicators to locally display digital input status. Moreover, the module offers
3000 V
DC
optical isolation between channels and backplane bus. If any high voltage or current damages
the channels, the system (backplanes, other modules, and control unit) won't be affected because of the
benefits of isolation.
