PI-32B(PCI)H

32 opto‑isolated digital inputs (current sink compatible) on a PCI board. All inputs can be used as interrupts with selectable edge triggering. Digital filter rejects noise and contact bounce. Internal 12 VDC power supply for opto‑couplers – no external supply needed.

The PI‑32B(PCI)H provides 32 opto‑isolated digital input channels (current sink compatible) on a PCI bus board. It accepts 12‑24 VDC signals and features a response time of 200 µsec. All inputs can be used as interrupt request signals with per‑bit enable/disable and selectable edge triggering.

• Opto‑isolated inputs — 1000 Vrms isolation between PC bus and input interface, excellent noise immunity.
• Digital filter — prevents false recognition from noise or chattering; software‑configurable for all inputs.
• Interrupt on all channels — edge selectable (rising/falling) per bit; disable/enable in bit units.
• Flexible power — internal 12VDC supply or external 12‑24VDC; jumper selection per 16 channels.
• Compact design — 121.69(L) x 105.68(H) mm, fits standard PCI slots.

The board uses a 37‑pin D‑SUB connector (female). Pin assignments include I‑00 to I‑31 (inputs), common minus pins for +0/+1 ports, and a supply power jumper. A separate common terminal is provided per 16 channels.

• Input common — separate common per 16 channels; supports different external power supplies for each block.
• Internal power option — jumpers let you select internal (12V) or external supply per 16‑point group.
• Optional cables — shielded and flat cables (PCB37PS, PCB37P, PCA37PS, PCA37P) from 0.5m to 5m.
• Terminal boards — EPD‑37A (M3 spring‑up), EPD‑37 (M3.5), DTP‑3C, DTP‑4C, CIM‑32L signal monitor.

• 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.
