When choosing your logo when do you decide to use either the following.

Relay contacts or Transitor outputs

Thanks

The output of the transistoroutput is always the same as the power to the LOGO and is suppleyed by the power of the LOGO!, its always 24VDC.

With relais contacts you are independet to the power of the LOGO. The relaiscontacts are potential-free, so you can use them on different voltages,.

Pe you can use Q1 on 230VAC, Q2 on 24VDC, Q3 on 12 VAC etc.

Transistoroutputs are more Quick, so you can switch faster (PWM)

Transistoroutputs make no noise when switching. Relais you can hear when switching.

Transistoroutputs have an internal electronic "fuse" (current limmetter)
