Image 4: Internal logic function SWITCH
The current state of the digital input DIx defines the state of the mapped relay output ROx. Only one digital
input must be mapped onto the relay output. IN this mode you cannot overwrite the relay output with serial
commands.

Image 6: Internal logic functions SWITCH ON, SWITCH OFF, TOGGLE and PULSE
If the module detects a rising edge on one of the mapped digital inputs, the affected relay output is
switched into a certain state:
SWITCH ON function: relay will be turned on
SWITCH OFF function: relay will be turned off
TOGGLE function: current relay state will be inverted
PULSE function: relay will be turned on for a adjustable PULSE TIME.
In between the relay state can be changed by serial commands
