3.3.2 Switch Output "DO” and S0 Interface
With switch output "DO,” whether the input signal exceeds or falls below the threshold
values can be reported. If it does, the output is set to +24 VDC and delivers a maximum
current of up to 100 mA. Then, e.g., an LED can be actuated.
More detailed information is presented in the following sections:
