TU507-ETH and TU508-ETH for ETHERNET Communication Interface Modules¶
- TU507-ETH, ETHERNET terminal unit, screw-type terminals
- TU508-ETH, ETHERNET terminal unit, spring terminals
- XC version for usage in extreme ambient conditions available (TU508-ETH only)
The ETHERNET communication interface modules plug into the ETHERNET terminal unit. When properly seated, they are secured with two mechanical locks. All the electrical connections are made through the ETHERNET terminal unit, which allows removal and replacement of the ETHERNET communication interface modules without disturbing the wiring at the ETHERNET terminal unit.
The ETHERNET terminal units TU507-ETH and TU508-ETH are specifically designed for use with AC500/S500 ETHERNET communication interface modules (e. g. CI501-PNIO).

Note
For a detailed description of the mounting, disassembly and electrical connection of the terminal units and the I/O modules, please refer to the “System Assembly, Construction and Connection” chapter AC500 (Standard).
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
Terminals 1.9, 2.9 and 3.9: Process supply voltage ZP = 0 V
The assignment of the other terminals is dependent on the inserted communication interface module.
Attention
:strong:Risk of corrosion!
Unused connectors and slots may corrode if XC devices are used in salt-mist environments.
Protect unused connectors and slots with TA535 protective caps for XC devices TA535: Protective Caps TA535 for XC Devices TA535 - Protective Caps for XC Devices.
