SCF Controller Circuit Boards (Intelligent)
BJJ1 or BJJ2
Intelligent
Controller Power
Boards Required for any intelligent features. Provides power to the intelligent
controller board and intelligent option boards.
BJJ1 is for 48 volt systems; BJJ2 is for 24 volt systems.
BJH Intelligent
Controller Board Required for all the intelligent functions of the Galaxy SCF Controller.
Contains the microprocessor, memory, real time clock, various serial
interfaces, and interface circuitry to the other intelligent circuit packs.
Enables “intelligent” features, including alarm history, battery reserve
time prediction, peripheral monitoring and control, etc.
Also provides access to the TL1/X.25 interface.
BJL2 Modem
Board Required for data access over telephone lines. Provides the modem
circuitry needed to interface the controller from a remote location over
the switched telephone network at up to 14,400 baud.
BJM1 Peripheral
Monitoring Board Required for any peripheral monitoring or control. Provides interface
circuitry for up to 255 remote monitoring modules, allowing
connections to as many as 1,530 monitoring points.
BJK1 Data Switch Required to operate the Data Switch, an optional interface with XCS,
ECS, RAS, and OMNIpulse units. Data Switch allows call-in and
call-out access to as many as four RS-232 devices via the Galaxy access
ports.
