DI-32B-PE

32 opto‑isolated digital inputs for PCI Express. The DI‑32B‑PE accepts 12‑24 VDC signals with internal or external power supply per 16‑point bank. All inputs can generate interrupts, and a programmable digital filter prevents noise and chattering. Windows/Linux drivers included. From Contec Americas.

The DI‑32B‑PE provides 32 opto‑isolated digital input channels for PCI Express systems. Supporting 12‑24 VDC signals, it is ideal for industrial automation, machine control, and sensing applications. The internal power supply (12VDC, 240mA) can drive optocouplers without external power, with jumper‑selectable internal/external per 16‑point bank.

Engineered for demanding factory automation and machine control applications. The digital filter prevents false triggering from noise or contact bounce, and the interrupt capability on every input enables real‑time event handling.

• Opto‑isolated inputs – 32 channels with 12‑24 VDC support. Common terminal per 16 channels.
• Internal power supply – 12VDC 240mA available to drive optocouplers. Jumper‑selectable internal/external per 16‑point bank.
• Digital filter – Programmable filter on all inputs prevents false triggers from noise or chattering.
• Interrupt on all inputs – Each input can generate an interrupt on rising or falling edge. Enable/disable per bit.
• Up to 16 boards per system – Scale input capacity with multiple DI‑32B‑PE boards in the same PC.

* PCB37P or PCB37PS cable required for terminal units. Visit CONTEC website for latest options.
