Technical data

DC541-CM interrupt I/O and fast counter module
In the operating mode counter, the channels can be configured as follows:
Input, Output, 32-bit up/down counter (uses C0...C3) as a 32-bit counter without limit, 32-bit periodic
counter as a 32-bit counter with a limit, limiter for a 32-bit counter (limit channel 0), 32-bit up counter
(forward counter) with the frequencies 50 kHz, 5 kHz and 2.5 kHz, pulse-width modulation (PWM) with
a resolution of 10 kHz, time and frequency measurement, frequency output.
