4‑Channel 24‑Bit
Up/Down Counter

The CNT24‑4(PCI)H provides four 24‑bit up/down counter channels on a PCI board. It supports opto‑isolated (500 kHz) or TTL‑level (1 MHz) input selection per channel. Counts 2‑phase (quadrature) or single‑phase signals from rotary encoders, linear scales, and other pulse sources.

Counter Features
  • 4 independent 24‑bit counters
  • Opto-isolated or TTL input (software select)
  • 500 kHz (opto) / 1 MHz (TTL) max input
  • 2‑phase or single‑phase counting
  • General‑purpose input per channel
Output & Timing
  • Count match interrupt (per channel)
  • One‑shot match output (opto-isolated)
  • Programmable timer (1 ms – 200 sec)
  • Digital filter per channel
  • PCI Universal key (requires +5V)

Flexible input selection — each channel can be independently configured for opto‑isolated or TTL‑level input via software. Count match events can generate interrupts and/or output pulses.

Built for Precision Counting

  • Flexible input — opto‑isolated (500 kHz) or TTL (1 MHz) input per channel; software selectable.
  • Count match — generate interrupt and/or one‑shot output when count matches preset value.
  • Programmable timer — 1 ms to 200 sec for periodic interrupt generation.
  • Digital filter — programmable per channel (0.1 µsec to 1056.1 µsec) to reject noise.
  • General‑purpose input — one per channel (opto‑isolated and TTL‑level).
  • Universal key PCI — compatible with 3.3V and 5V slots (requires +5V supply).

Connector & Cabling

The board uses two connectors: CN1 for opto‑isolated inputs (37‑pin D‑SUB) and match outputs, and CN2 for TTL‑level inputs (30‑pin header). CN1 includes phase inputs, general‑purpose inputs, common pins, and match outputs. CN2 provides TTL inputs with +5V output (500 mA max).

  • CN1 (Opto‑isolated) — 37‑pin D‑SUB: phase A/B/Z inputs, general‑purpose inputs, plus common, match outputs.
  • CN2 (TTL‑level) — 30‑pin header: phase A/B/Z inputs, general‑purpose inputs, Vcc (+5V output), GND.
  • Vcc output — +5V power (500 mA max) for external devices such as encoders.
  • Optional cables — shielded/flat 37‑pin D‑SUB cables (PCB37PS, PCB37P), 30‑pin to 37‑pin conversion cable (D7/B2).
  • Terminal boards — EPD‑37A (M3 spring‑up), EPD‑37 (M3.5), 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.
