| High‑frequency pulse clock source | 4 MHz |
|---|---|
| Low‑frequency pulse clock source | 100 kHz |
| Pulse count register width | 32‑bit |
| Terminal block pins | 16‑pin |
| Maximum pulse frequency | 400 kHz |
High‑frequency pulses are generated by an internal 4 MHz counter that can produce output frequencies from 100 Hz up to 400 kHz.
Each PTO channel uses a 32‑bit counter to count the number of output pulses.
