The National Instruments PCI-6519 board offers 16 optically isolated sink/source input channels, and 16 optically isolated sink output channels with low-cost 37-pin accessory connectivity. The NI PCI-6519 inputs and outputs are optically isolated in banks of 16 channels. With programmable power-up states, you can configure the initial output states in software, to ensure safe operation when connected to industrial actuators (pumps/valves/motors/relays). Using digital I/O watchdogs, the board can go to a configurable safe output state if a computer or application fault occurs. NI-DAQmx makes it fast and easy to configure your board and take advantage of all the high-reliability industrial features with automatic code generation in LabVIEW, ANSI C, Microsoft Visual C++, or Microsoft .NET Languages (C# and Visual Basic .NET). For optical isolation in banks of eight channels, consider the PCI-6515 board. For channel-channel isolation and a ±60 V output range, consider the PCI-6528 board.
