the electronic switch will be ON, and the multi-function output ports will be in the valid status.
The open collector can be powered on internally or by an external power supply (12-30V).
The relay output is from the internal
relay of the inverter. The relay has one set of
normally open contacts and one set of
normally closed contacts. When the selected
function is disabled, the EB-EC is normally
closed and EA-EC is normally open. When
the selected function is enabled, the internal
relay coil will be powered on, the EB-EC
will be disconnected, and the EA-EC will be
