ABB NU8976A HIEE320693R0001 function board
CMU modules available:
• Serial Line Interface board 560SLI02
• Ethernet Adapter board 560ETH03
• Communication Unit 560CMU04
• Communication Unit 560CMU80
Each CPU communication board has an additional
serial interface for MMI to a PC. The MMI is used
for diagnostics,up and download of configuration
files,etc.
I/O Boards
Only five I/O board types are needed to cover the
main requirements for the I/O signals connected to
the RTU. This is possible because of a microprocessor-controlled kernel module which is identical on
all types of I/O boards,whereas the individual I/O
function is provided by type specific hardware circuit extensions to the kernel.
• Binary Input Board 23BE21
• Binary Output Board 23BA20
• Binary Output Supervision Board 23BA22
• Analog Input Board 23AE21
• Analog Output Board 23AA20
Direct interfacing of 110-220 V DC binary IO
without interposing relays is possible with:
• Binary Input Board 23BE40
• Binary Output Board 23BA40
Modems
For communication with telecontrol lines differnt
types of FSK Modems are available:
• Universal FSK Modem 23WT22
• V.23 Modem 23WT23
• 9600 bps FSK Modem 23WT24
For fibre optic communication are available:
• fibre optic coupler 23OK22
RTU560 does also provide interfaces to all kind of
analog and digital comminication equipement.

Configurable Process Data Points
Overall total per RTU560 approx.3000 directly connected data
points,including data points from IEDs and subordinate RTUs.
Higher volumes are possible on request.
