PI-128L(PCI)H

128 opto‑isolated digital inputs (current sink compatible) on a PCI board. 16 inputs can be used as interrupts with selectable edge triggering. Digital filter rejects noise and contact bounce. Common terminals per 16 channels support different external power supplies.

The PI‑128L(PCI)H provides 128 opto‑isolated digital input channels (current sink compatible) on a PCI bus board. It accepts 12‑24 VDC signals and features a 200 µs response time. 16 of the inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.

• Opto‑isolated inputs — 250 Vrms isolation between PCI bus and input interface, excellent noise immunity.
• Digital filter — prevents false recognition from noise or chattering; software‑configurable for all inputs.
• Interrupt on 16 channels — edge selectable (rising/falling) per bit; disable/enable in bit units.
• Flexible power — external 12‑24 VDC supply; common terminals per 16 channels allow different supplies.
• Extreme density — 128 channels in a single PCI slot.

The board uses two 100‑pin connectors (CNA and CNB). Pin assignments: I‑00 to I‑7F (128 input pins), IP‑0/1 through IP‑E/F (input common positive), and NC. Input signals are optically isolated and current sink compatible.

• Input common — positive side of external supply; separate common per 16 channels.
• Current sink compatible — inputs ready to accept current sinking output signals.
• Optional cables — shielded 100‑pin cables (PCB100PS), conversion cables to 96‑pin (PCB100/96PS) and 37‑pin D‑SUB (PCB100WS).
• Terminal boards — EPD‑100A (M3 × 100), EPD‑96A, EPD‑96, EPD‑37A, EPD‑37, DTP‑64A, DTP‑3C, DTP‑4C; signal monitor CIM‑64L; connector conversion board CCB‑96.

• VCCI Class A — Japanese EMC for commercial/industrial environments.
• FCC Class A — U.S. emissions compliance for industrial use.
• CE (EMC Directive Class A + RoHS) — European conformity.
• UKCA — UK conformity assessed.
