The F-8041 is a digital output module with 32 NPN channels. The output channel of F-8041 is a current sinking channel and can drive the load up to 0.5A current. The digital output channels offer LED to indicate digital output status. Moreover, the module offers 3000 VDC 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 the benefit of isolation.
