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 16/DO 
16 x DC 24 V/0.5 A, its outputs will carry "1" signal for the duration of approx. 50 µs, due to 
the circuit structure.
