eWON Cosy 131 Ethernet User Manual

Appendix A - Connector Pinout & Related
Specifications
The digital output is activated by an open drain MOSFET transistor driven by an optocoupler.
The maximum current flow inside this transistor has a value above the one specified in the
eWON, in order to cope with the switching power losses.
The transistor used is in an open drain type with predrive. This means the relay power supply
has to be supplied from an external source to the predrive electronics. The diagram below
shows the external wiring needed for proper operation of the digital output. A relay has
been chosen for this sample application but any load within the specifications can be used
instead.
- Note -
This is a sink only output to ground (the transistor acts like a switch ground).
Possible features :
Digital Output & Inputs can be used on the COSY 131, some features can be externalized by
wiring the main connector.
