Digital Input Board with Opto-Isolation for PCI Express

This product is a PCI Express bus-compliant interface board for digital signal input (12-24VDC). DI-128L-PE features 128ch opto-coupler isolated inputs (for use with current sink outputs), with 16ch of the inputs having an interrupt function. This product also has a digital filter function to help prevent mis-detection of input signals. With the driver libraries for Windows/Linux supplied as standard, applications with CONTEC hardware features fully utilized can be created. LabVIEW is supported with a plug-in of dedicated libraries.

	Opto-coupler isolated inputs (for use with current sink outputs): DI-128L-PE board has 128ch opto-coupler-isolated inputs with a 200uSec response time (for use with current sink outputs). A separate common ground is provided for each block of 16ch inputs which means that each block can connect to a different external power supply. The drive voltage for both the inputs and outputs is 12 - 24VDC.
	Opto-coupler bus isolation: As the PCI Express bus (PC) is isolated from external signals by opto-couplers, this product has excellent noise immunity.
	16ch of the input signals can be used as interrupt input: 16ch of all input channels can be used as interrupt request signals and the interrupt enable/disable and interrupt detection edge can be set independently for each interrupt bit.
	Windows/Linux compatible driver libraries are attached: Bundled driver library API-PAC(W32) enables to create Window/Linux applications. In addition, a diagnostic program by which the operations of hardware can be checked is provided.
	This product has a digital filter to prevent input signals from carrying noise or a chattering. A digital filter which can prevent the misrecognition by the noise and chattering of input signal is equipped. All input terminals can be added a digital filter, and the setting can be performed by software.
	Functions and connectors are compatible with PCI compatible board. The functions same with PCI compatible board PI-128L(PCI)H are provided. In addition, as there is compatibility in terms of connector shape and pin assignments, it is easy to migrate from the existing system.
