Wiring jacks (DI/DQ) for Y cable
To connect digital inputs via a Y cable, you will need:
• A Y cable
• 2 M12 jacks
• A flexible 3-wire or 4-wire copper cable
The assignment of Pin 4 depends on which socket of the ET 200eco PN the Y cable is screwed
to.
Pin assignment of the sockets for inputs/outputs
The pin assignment of the sockets for inputs/outputs can be found in the data for the
individual I/O devices starting in sectionPin assignment of digital inputs (Page 41).
Wiring M12 jacks for analog inputs and analog outputs
For the connection of analog inputs and outputs, you will need:
• one 4-pin or 5-pin M12 jack
• a shielded 4-wire copper cable with a wire cross-section of ≤ 0.75 mm
2
Wire the jack according to the pin assignment of the sockets on the I/O device. You can find
the pin assignment in the data for the individual I/O devices starting in Chapter Pin
assignment for analog inputs (Page 50).
NOTE
Coupler plug for RTD measurement
For RTD measurements, use a coupler plug with gold-plated contacts. Other materials can
create contact resistance that can result in incorrect measured values.
Sealing round sockets not in use
Always seal all unused round sockets using M12 sealing caps to achieve degree of protection
IP65, IP66 or IP67.
