Figure: Types of terminals
The Ethernet Terminal Units TU507-ETH (with screw-type terminals) and TU508-ETH (with spring terminals) are specifically designed for use with AC500/S500 Ethernet Bus Modules (e. g. CI501-PNIO).
The Ethernet Bus 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 Bus Modules without disturbing the wiring at the Ethernet Terminal Unit.
Note
Note: Mounting, disassembling and electrical connection for the Terminal Units and the I/O modules are described in detail in Mounting and disassembling the Terminal Units and the I/O modules Mounting and Disassembling the Terminal Units and the I/O Modules.
The terminals 1.8 and 2.8 as well as 1.9, 2.9 and 3.9 are electrically interconnected within the Ethernet Terminal Unit and have always the same assignment, independent of the inserted Bus 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 PROFINET®- or EtherCAT® Bus Module (see Ethernet Bus Modules Overview).
For usage in extreme ambient conditions (e.g. wider temperature and humidity range), a special XC version of the device is available (TU508-ETH only).
