16 opto‑isolated inputs (current sink compatible) and 16 opto‑isolated open‑collector outputs (current sink type) on a PCI board. 12‑24 VDC operation, 200 µs response, interrupt on all inputs, digital filter, surge and overcurrent protection.
Isolated Digital I/O
for Industrial Control
The PIO‑16/16L(PCI)H provides 16 opto‑isolated inputs (current sink compatible) and 16 opto‑isolated open‑collector outputs (current sink type) on a PCI bus 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.
- 16 channels, opto-isolated
- Current sink compatible
- 12‑24 VDC external supply
- Common terminal per 16 channels
- All inputs can be interrupt sources
- 16 channels, open-collector
- Current sink type
- 35 VDC max, 100 mA per channel
- Zener diode surge protection
- Overcurrent protector (8 ch/group)
Opto‑isolated bus — 1000 Vrms isolation between PCI bus and I/O interfaces, excellent noise immunity. Surge protection (zener diode) and overcurrent protection per 8 output channels.
Built for Reliable Operation
-
Opto‑isolated bus — 1000 Vrms isolation between PCI bus and I/O interfaces, excellent noise immunity.
-
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.
-
Compact design — 121.69(L) × 105.68(H) mm.
