32-bit high-speed digital input board with 6 front-panel channels. Trigger logic and trigger threshold are programmable; the effective threshold can be checked with a meter from a front-panel test point. Built-in frequency, period and RPM counting.
The same input function is also available on the R combined I/O modules, which mix inputs and outputs on one board over optical links (TX/RX, 50 or 100 MHz link clock) and can also be used to remotize the I/O.
