Installation of EJ modules
EJ6002 24 Version: 1.5
E-bus power supply with CXxxxx and EK1110-004x
The Embedded PC supplies the attached EtherCAT Terminals and the EtherCAT EJ coupler
• with a supply voltage Us of 24 V
DC
(-15 %/+20%). This voltage supplies the E-bus and the bus terminal
electronics.
The CXxxxx units supply the E-bus with up to 2,000 mA E-bus current. If a higher current is required
due to the attached terminals, power feed terminals or power supply plug-in modules must be used for
the E-bus supply.
• with a peripheral voltage Up of 24 V
DC
to supply the field electronics.
The EK1110-004x EtherCAT EJ couplers relay the following parameters to the signal distribution board via
the rear connector:
• the E-bus signals,
• the E-bus voltage U
EBUS
(3.3 V) and
• the peripheral voltage U
P
(24 V
DC
).
