DI-128L-PE

128‑channel opto‑isolated digital input for PCI Express. The DI‑128L‑PE supports 12‑24 VDC signals with 16 interrupt inputs, digital filter, and common terminals per 16 channels. Windows/Linux drivers included. From Contec Americas.

The DI‑128L‑PE provides 128 opto‑isolated digital input channels on a single PCI Express board. Supporting 12‑24 VDC signals with 200µsec response time, it is ideal for large‑scale industrial monitoring, factory automation, and machine interface applications. Common terminals are provided per 16 channels, allowing different external power supplies for each bank.

Designed for systems requiring a large number of digital input points. The DI‑128L‑PE offers 128 channels in a single PCI Express slot, reducing system cost and complexity. The opto‑isolated design provides 250Vrms isolation between the PCIe bus and input interfaces for excellent noise immunity.

• Opto‑isolated inputs – 250Vrms isolation between PCIe bus and input interfaces.
• Common per 16 channels – Supports different external power supplies for different banks.
• Interrupt capability – 16 input signals can generate interrupts with independent edge selection.
• Up to 16 boards per system – Scale input capacity with multiple boards in the same PCIe system.
• Connector compatible – Same connector as PI‑128L(PCI)H for easy system migration.

* Various cables and terminal blocks available. Refer to datasheet for compatibility. Visit CONTEC website for latest options.
