Electrical Connection

The FBP Interface Module is plugged on the FBP Terminal Unit TU505 FBP Terminal Units TU505-FBP and TU506-FBP for FBP Interface Modules\ or TU506 FBP Terminal Units TU505-FBP and TU506-FBP for FBP Interface Modules\. Hereby, it clicks in with two mechanical locks. The Terminal Unit is mounted on a DIN rail or with 2 screws plus the additional accessory for wall mounting (TA526 Wall Mounting Accessory TA526).

The electrical connection of the I/O channels is carried out using the 20 terminals of the FBP Terminal Unit. It is possible, to replace FBP Interface Modules and I/O modules without loosening the wiring.

Note

Mounting, disassembling and electrical connection for the Terminal Units, the FBP Interface Modules and the I/O modules are described in detail in S500 system data chapters.

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:

Terminals	Signal	Meaning
1.0 to 1.7	I0 to I7	8 digital inputs
2.0 to 2.7	C8 to C15	8 digital inputs/outputs

The supply voltage 24 V DC for the module’s electronic circuitry comes from the FieldBusPlug.

The module provides several diagnosis functions FBP Interface Module DC505-FBP with Digital Inputs and Outputs.

Caution

Removal of energized modules is not permitted. All power sources (supply and process voltages) must be switched off while working on any AC500 system.

The following figure shows the electrical connection of the FBP Interface Module DC505-FBP.
