Negative‑Common Isolated I/O
for Current Source Applications

The DIO‑1616RL‑PE provides 16 opto‑isolated inputs (compatible with current source output) and 16 opto‑isolated open‑collector outputs (current source type) on a PCI Express board. It features negative‑common configuration with positive logic. All 16 inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.

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

Negative‑common configuration — inputs use negative common (IN‑0/1); outputs use positive common (OP‑2/3). Positive logic: ON = High level ("1"). Compatible with PIO‑16/16RL(PCI)H for easy migration.

Built for Reliable Operation

  • Opto‑isolated bus — 1000 Vrms isolation between PCI Express bus and I/O interfaces, excellent noise immunity.
  • Current source I/O — inputs compatible with current source output; outputs are current source type (PNP).
  • Positive logic — data "1" corresponds to High level; data "0" corresponds to Low level.
  • 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 16 inputs — edge selectable (rising/falling) per bit; disable/enable in bit units.

Connector & Cabling

The board uses a 37‑pin D‑SUB connector (female). Pin assignments: I‑00 to I‑17 (inputs), O‑20 to O‑37 (outputs), IN‑0/1 (input common negative), OP‑2/3 (output common positive), and NC. Positive logic: ON = High level.

  • Input common (IN‑0/1) — negative side of external supply; common to 16 input signals.
  • Output common (OP‑2/3) — positive side of external supply; common to 16 output signals.
  • Positive logic — ON = High level ("1"); OFF = Low level ("0").
  • Optional cables — shielded/flat 37‑pin D‑SUB cables (PCB37PS, PCB37P).
  • Terminal boards — EPD‑37A (M3 spring‑up), EPD‑37 (M3.5), DTP‑3C, DTP‑4C.

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.
