● 8 digital outputs 24 V DC in 1 group (3.0...3.7)
● Cam switch functionality
The inputs/outputs are galvanically isolated from the Ethernet network. There is no potential
separation between the channels. The configuration of the analog inputs/outputs is performed
by software.

1.7.3.1.3 Connections
The Ethernet communication interface module CI511-ETHCAT is plugged on the I/O terminal
unit TU507-ETH or TU508-ETH. Properly seat the module and press until it locks in place. The
terminal unit is mounted on a DIN rail or with 2 screws plus the additional accessory for wall
mounting (TA526).
The connection of the I/O channels is carried out using the 30 terminals of the I/O terminal unit.
I/O modules can be replaced without re-wiring the terminal units.
The terminals 1.8 and 2.8 as well as 1.9, 2.9 and 3.9 are electrically interconnected within the
terminal unit and have always the same assignment, independent of the inserted module:
Terminals 1.8 and 2.8: Process supply voltage UP = +24 V DC
Terminal 3.8: Process supply voltage UP3 = +24 V DC
