4‑Channel 24‑Bit
Differential Up/Down Counter

The CNT24‑4D(PCI)H provides four 24‑bit up/down counter channels on a PCI board. It supports differential line receiver or TTL‑level 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
  • Differential or TTL input (software select)
  • 1 MHz max input frequency
  • 2‑phase or single‑phase counting
  • General‑purpose input per channel
Output & Timing
  • Count match interrupt (per channel)
  • One‑shot match output (selectable OC/TTL)
  • 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 differential or TTL‑level input via software. Count match events can generate interrupts and/or output pulses.

Built for Precision Counting

  • Flexible input — differential (1 MHz, up to 1200m) 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 (differential and TTL‑level).
  • Universal key PCI — compatible with 3.3V and 5V slots (requires +5V supply).

Connector & Cabling

The board uses a 96‑pin half‑pitch connector (CN1). Signals include differential/TTL phase inputs, general‑purpose inputs, one‑shot outputs, ground, and NC. Termination resistors can be enabled/disabled via switches.

  • Differential inputs — line receiver inputs with 100Ω termination (switchable), ±200mV sensitivity, ±7V common‑mode range.
  • TTL inputs — standard TTL‑level inputs, 1.5m cable length max.
  • One‑shot outputs — selectable open‑collector (50V, 90mA) or TTL via SW2.
  • Optional cables — shielded/flat 96‑pin half‑pitch cables (PCB69PS, PCB69P), distribution cables to 37‑pin D‑SUB (PCB69WS).
  • Terminal boards — EPD‑96A (M3 × 96), EPD‑96, EPD‑37A, EPD‑37, DTP‑64A, DTP‑3C, DTP‑4C; connector conversion board CCB‑96.

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.
