Isolated Digital I/O
for Industrial Control

The DIO‑3232L‑PE provides 32 opto‑isolated inputs (current sink compatible) and 32 opto‑isolated open‑collector outputs (current sink type) on a PCI Express board. It accepts 12‑24 VDC signals and features a 200 µs response time. All 32 inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.

Input Features
  • 32 channels, opto-isolated
  • Current sink compatible
  • 12‑24 VDC external supply
  • Common terminal per 16 channels
  • All inputs can be interrupt sources
Output Features
  • 32 channels, open-collector
  • Current sink type
  • 35 VDC max, 100 mA per channel
  • Zener diode surge protection
  • Overcurrent protector (8 ch/group)

Isolation & protection — opto‑coupler bus isolation (1000 Vrms), digital filter, surge protection (zener diode), and overcurrent protection per 8 output channels.

Built for Reliable Operation

  • Opto‑isolated bus — 1000 Vrms isolation between PCI Express bus and I/O interfaces, excellent noise immunity.
  • Surge protection — zener diode (RD47FM or equivalent) on each output transistor.
  • Overcurrent protection — per 8 output channels; protects output transistors from excessive current.
  • Digital filter — software‑configurable per input to reject noise and contact bounce.
  • Interrupt on all 32 inputs — edge selectable (rising/falling) per bit; disable/enable in bit units.
  • Compatibility — same functions and connector pinout as PIO‑32/32L(PCI)H for easy migration.

Connector & Cabling

The board uses a 96‑pin half‑pitch connector (CN1). Pin assignments: I‑00 to I‑37 (inputs), O‑40 to O‑77 (outputs), IP‑0/1 and IP‑2/3 (input common positive), OP‑4/5 and OP‑6/7 (output common positive), ON‑4/5 and ON‑6/7 (output common negative), and NC. One pin permissible current is 1A; connect multiple pins for higher total current.

  • Input common — positive side of external supply; separate common per 16 channels (IP‑0/1 and IP‑2/3).
  • Output common — positive and negative sides; separate common per 16 channels. Connect multiple pins for full 100mA/channel load.
  • Optional cables — shielded/flat 96‑pin half‑pitch cables (PCB69PS, PCB69P), conversion cables to 37‑pin D‑SUB (PCB69WS).
  • Terminal boards — EPD‑96A (M3 × 96), EPD‑96, EPD‑37A, EPD‑37, DTP‑64A, DTP‑3C, DTP‑4C; signal monitors CIM‑64L, CIM‑32L; connector conversion board CCB‑96.

Certifications & Compliance

  • 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.
