4‑channel 32‑bit isolated up/down counter for USB. The CNT‑3204IN‑USB counts two‑phase and single‑phase signals at up to 500 kHz – ideal for rotary encoders and linear scales. Features opto‑isolated inputs, control I/O, digital filter, sampling timer, and interrupt support. Windows driver included. From Contec Americas.
The CNT‑3204IN‑USB is a USB2.0 counter unit that adds four channels of 32‑bit up/down counting to any PC. It counts two‑phase (A/B) and single‑phase signals from rotary encoders, linear scales, and other pulse generators at up to 500 kHz. The opto‑isolated inputs provide excellent noise immunity, and the unit includes control I/O, sampling timer, and interrupt capabilities for advanced measurement and control applications.
