L-Tron

The PCI-1756 cards offer the isolated digital input channels and isolated digital output channels with isolation protection up to 2,500 VDC , which makes it ideal for industrial applications where high-voltage isolation is required. In addition, all output channels are able to keep their last values after a hot system reset.

Main Features
