PEX-730A_DESCRIPTION.html
PEX-730A cards provide 32-channel isolated digital I/O (16 x DI and 16 x DO) and 32-channel TTL-level digital I/O
(16 x DI and 16 x DO). The isolated DI and DO channels are a short optical transmission path that transfers an
electronic signal between the elements of a circuit, keeping them electrically isolated. With 3750 Vrms isolation
protection, these DIO channels allow the input signals to be completely floated, preventing ground loops and isolating
the host computer from damaging voltages. Each digital output offers a Darlington (NPN) transistor and integrated
suppression diode for the inductive load. The open collector outputs (DO channels) functions as an alarm and warning
notification, signal output control, control for external circuits that require a higher voltage level, and signal
transmission applications, etc.
