GE Digital 8922-RB-IS Specifications

PAC8000 Railbus Isolator

The PAC8000 Railbus Isolator is required when using any 2/1 modules in a node. The unit provides
galvanic isolation between those modules interfacing to Intrinsic Safe field wiring on the 2/1 side
of the isolator and those with conventional wiring on the 2/2 side. The unit mounts on its dedicated
Railbus Isolator Carrier 8725-CA-RB.
Note: System Power is not passed from one side of the Railbus Isolator to the other, so System
Power on the 2/1 side must be supplied by IS System Power Supplies.
