PI-32L(PCI)H

32 opto‑isolated digital inputs (current sink compatible) on a PCI board. All inputs can be used as interrupts with selectable edge triggering. Digital filter rejects noise and contact bounce. Compact 121.69 × 105.68 mm design.

The PI‑32L(PCI)H provides 32 opto‑isolated digital input channels (current sink compatible) on a PCI bus board. It accepts 12‑24 VDC signals and features a response time of 200 µsec. All 32 inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.

• Opto‑isolated inputs — excellent noise immunity, isolates PCI bus from input interface.
• Digital filter — prevents false recognition from noise or chattering; software‑configurable for all inputs.
• Interrupt on all 32 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.
• Compact design — 121.69(L) × 105.68(H) mm, fits standard PCI slots.
• Backward compatible — connector‑pin compatible with PI‑32L(PCI).

The board uses a 37‑pin D‑SUB connector (female). Pin assignments: I‑00 to I‑37 (inputs), IP‑0/1 (positive side of external supply for inputs 00‑17), IP‑2/3 (positive side for inputs 20‑37), and NC.

• Input common — separate common per 16 channels (IP‑0/1 and IP‑2/3); supports different external power supplies for each bank.
• Current sink compatible — inputs ready to accept current sinking output signals.
• Optional cables — PCB37P or PCB37PS flat/shielded cables (0.5m to 5m).
• Terminal boards — EPD‑37A (M3 spring‑up), EPD‑37 (M3.5), DTP‑3C, DTP‑4C.

• 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.
