Use of the module with high-speed counters
Please note when using the module in combination with high-speed counters:
Note
When using a mechanical contact to switch on the 24
-V power supply to
SM 323; DI 8/DO 8
x DC 24 V/0.5 A, its outputs will carry "1" signal for the duration of ca. 50
µs, due to the circuit structure.
