PF900-NR 3BDH000357 DP/PA linking device LD 800P

The power feed module supplies the Power Rail with a voltage of 24 V DC and a maximum current of 4 A.
The dual designed power feed terminals 8+ and 11+ or 9- and 12- have the ability to loop the supply (up to a max. of 10 A). The integrated fault evaluation detects shorts and possible collective error messages. In a fault condition, the relays switch closed (terminals 7 and 10) and the fault is indicated by means of a red LED on the front panel. The mode of operation can be adjusted with a plug-in jumper. The terminals 13 and 15 are for the bus connection (only with Power Rail PR 900-N). The terminal 14 is the measuring point for the collective error message (only planned for inspection or test, may not be wired into the system).

APPLICATION

The ABB PF900-NR 3BDH000357 is the FieldIT PF900-NR Power Feed Module manufactured by ABB. Here are some of the key features and functions of the product:
Function: This Power module provides 24 V DC voltage and up to 4 A current to Power Rail.
Power supply: With dual design of power input terminals 8+ and 11+ or 9- and 12-, capable of cyclic power supply (up to 10 A).
Fault detection: Integrated fault assessment can detect short circuits and possible collective error messages.
Fault signal output: Under fault conditions, the relay closes (terminals 7 and 10) and indicates the fault via a red LED on the front panel.
Adjustable operation mode: The operation mode can be adjusted through the plug-in jumper.
Connections: Terminals 13 and 15 are used for bus connections (only in conjunction with Power Rail PR900-N). Terminal 14 is the measuring point for the collective error message (used only for inspection or testing and may not be connected to the system).
Redundant Power supply: Two power supply modules can be used as redundant power supply on Power Rail via reverse diode “R”.
