The digital input module receives control signal from the digital field devices
(sensors, etc.).
IN
t < 1ms 1ms < t < 10ms Retrigger t < 10ms t > 10ms
This input module extends input signals to at least 10ms. Only signals ≥ 1ms
will be acquired. Input signals > 10ms will not be extended (see timing
technical data).
