- Provides local operator key entry for the associated Mark V interface
- BA603 suffix remains part of the complete keypad hardware identity
- Connector, key legend and host-interface assignment must match the installed unit
NP104X905BA603 is a legacy GE operator keypad used with a Mark V operator-interface arrangement rather than a turbine protection or I/O processor board.
Its purchasing risk lies in the physical execution: key legends, overlay, connector location, mounting cutout and host electronics can differ even when an assembly is described generically as NP104X905.
Public manufacturer material for the complete BA603 execution was not located, so communication protocol, supply voltage and environmental ratings are left unpublished until an exact drawing or label is available.
Availability, condition, price, and shipping time for NP104X905BA603 are confirmed during quotation.
