DIO-1616L-LPE

16 opto‑isolated inputs (current sink compatible) and 16 opto‑isolated open‑collector outputs (current sink type) in a Low Profile PCI Express form factor. 12‑24 VDC operation, 200 µs response, interrupt on all inputs, digital filter, surge and overcurrent protection. Includes standard bracket for standard‑size slots.

The DIO‑1616L‑LPE provides 16 opto‑isolated inputs (current sink compatible) and 16 opto‑isolated open‑collector outputs (current sink type) on a Low Profile PCI Express board. It accepts 12‑24 VDC signals and features a 200 µs response time. All 16 inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.

• Opto‑isolated bus — excellent noise immunity, isolates PCI Express bus from I/O interfaces.
• Surge protection — zener diode 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.
• Low Profile / standard — supports both form factors with interchangeable bracket.

The board uses a 50‑pin mini‑ribbon connector (CN1). Pin assignments: I‑00 to I‑17 (inputs), O‑20 to O‑37 (outputs), common pins (positive/negative), and NC. Inputs and outputs share common per 16 channels.

• Input common — positive side of external supply; common per 16 channels.
• Output common — positive and negative sides; common per 16 channels.
• Optional cables — shielded 50‑pin mini‑ribbon cables (PCB50PS, PCA50PS), conversion cable to 37‑pin D‑SUB (PCE50/37PS‑0.5P).
• Terminal boards — EPD‑50A (M3 × 50), EPD‑37A (M3 × 37), EPD‑37, DTP‑4C; signal monitor CIM‑32L.

• 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.
