Note
When a mechanical contact turns on output power to the S7
-200 SMART CPU, or any
digital
expansion module, it sends a "1" signal to the digital outputs for approximately 150
microseconds. This could cause unexpected machine or process operation which could
result in death or serious injury to personnel and/or damage to equipment. You must plan for
this, especially if you are using devices which respond to short duration pulses.
