See Input/Outputs
The input range extends from 0 to 24VDC (30VDC max). A zero logic (OFF) state is detected when the
input level is below 5Vdc. A one logic (ON) state is detected when the input level is above 10Vdc.

WARNING
-
The logic level is undefined when the input is ranging between 5 and 10VDC.

Value
Type of output
Open drain (MOSFET)
Max current (external source)
200mA @ 30 VDC
Isolation
3,5 kV
Pin-out connector
See Input/Outputs
This digital output is activated by an open drain MOSFET transistor driven by an optocoupler. The
maximum current flow into this transistor has a characteristic above the value specified in the eWON,
in order to cope with the switching power losses. The transistor used is in an open drain type with pre
drive. This means the relay power supply has to be supplied from an external source to the pre drive
electronics.
