32-Channel, ±30 V, Sink Outputs, Bank-Isolated Digital I/O Device—The PCI-6517 is an industrial digital output interface, with one bank of channels. The device is ideal for industrial control and manufacturing test applications. The PCI-6517 module is an industrial digital I/O interface, with eight banks of isolated channels. You can wire each input bank in a source or sink configuration. With programmable power-up states, you can configure the initial output states in software, to ensure safe operation when connected to industrial actuators. If a computer or application fault occurs, the PCI-6517 can use digital I/O watchdogs to switch to a configurable safe output state to ensure detection and safe recovery from fault conditions.
