16 opto‑isolated inputs (current sink compatible) and 16 opto‑isolated open‑collector outputs (current sink type) on a PCI board. On‑board 12VDC power supply for opto‑couplers — no external supply needed. 200 µs response, interrupt on all inputs, digital filter, surge and overcurrent protection.
The PIO‑16/16B(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 features an on‑board 12VDC power supply (240 mA) for driving opto‑couplers, eliminating the need for an external supply. All 16 inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.
On‑board power supply — 12 VDC, 240 mA provided for opto‑coupler operation. Jumpers let you choose internal or external power per block (inputs/outputs separately).
