2 I/O Port
The I/O part allows communication with external equipment via analog data
(programmable logic control - PLC). Through this connection some functions of the
Ecotec E3000 can be controlled externally or measurement data or the Ecotec E3000
status may be communicated to external equipment. Through relay changeover contacts
the trigger levels as well as the operating mode (Ready) of the Ecotec E3000 may be
monitored.

Hazardous voltage.
The wrong voltage may destroy the device and violate people.
► For all contacts of the I/O Port a maximum voltage of 60 V DC or 25 V AC must not be
exceeded or reached to ground or ground equipment conductors. According to the
type of in- or outputs lower voltages had to be accepted. For this, please refer to the
information given in the corresponding chapters.
