0 to 48 V isolated counter/timer
779474-01
The National Instruments SCC-CTR01 is an isolated general-purpose
counter/timer module for the SCC platform. This module performs in a
wide variety of counter/timer tasks, including quadrature encoder
measurement, edge counting, frequency measurement, pulse-width-
modulation (PWM) generation, and pulse-train generation.
With optical isolation, the test system and UUT are protected from
transient voltage spikes when the signals are connected to the
SCC-CTR01. The SCC-CTR01 also features short-circuit protection that
disables the outputs if current limits are reached.
