The NI SCC-CTR01 is a two input and one output isolation module for
general-purpose counter/timers on DAQ devices. The gate and source
inputs are optically isolated to allow an increased voltage range and protect
against common-mode voltages. The inputs also have reverse and
overvoltage protection. The output channel is isolated and has advanced
short-circuit protection, which allows the circuit to recover automatically
250 ms after a short is removed.
