Figure: Types of terminals

The FBP Terminal Units TU505-FBP (with screw-type terminals) and TU506-FBP (with spring terminals) are specifically designed for use with AC500/S500 FBP Interface Modules (e.g. DC505-FBP).

The FBP Interface Modules plug into the FBP Terminal Unit. When properly seated, they are secured with two mechanical locks. All the electrical connections are made through the FBP Terminal Unit, which allows removal and replacement of the FBP Interface Modules without disturbing the wiring at the FBP 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 to 2.8 and 1.9 to 2.9 are electrically interconnected within the FBP Terminal Unit and have always the same assignment, independent of the inserted module:

  • Terminals 1.8 to 2.8: Process voltage UP = +24 V DC
  • Terminals 1.9 to 2.9: Process voltage ZP = 0 V

The assignment of the other terminals is dependent on the inserted FBP Interface Module (see Overview of FBP Interface Modules S500 FBP Interface Modules Overview).

The supply voltage 24 V DC for the module’s electronic circuitry comes from the FieldBusPlug. If the FieldBusPlug is removed, the FBP Interface Module has no supply voltage. Also, all I/O expansion modules connected through the I/O-Bus have no supply for their electronic parts then.
