5. THE OUTPUT CONNECTOR FUNCTION

The output connectors can be used for a possible connection of a device designed for monitoring
or controlling the supply activity.
IN/OUT INTERFACE is intended for connection to protective hardware systems;
LAN connector can be used for communication purposes via ETHERNET interface in MODBUS
TCP protocol.
RS232 / RS485 connector can be used for communication purposes via RS232 / RS485 interface
in MODBUS RTU protocol.
(Modbus Application Protocol V1.1b3)

Pin layout of IN/OUT Interface connector

Interlock couple wires are open / short inputs. Short shall sustain at least 10 mA, open will present
a 5V voltage difference.
Alarm couple wires are open / short outputs. They can be read with a maximum voltage of 24 Vdc
and a maximum current of 500 mA.
