DC150 Data Concentrator
Function
The DC150 data concentrator is used to:
n Centralize all the information supplied by the various communicating devices:
o Auxiliary switches and motor operator
o SC150 indication and control interface
n Make information available to a personal computer or programmable logic controller (PLC) via the
MODBUS/JBUS protocol
n Log status changes and tripping of the communicating circuit breakers in order to provide the
user with a list of time-stamped events
n Supply the 24 V and 15 V power required by the communicating devices and the internal bus
n Carry out addressing for the communicating devices
Each DC150 data concentrator can be connected to a maximum of 48 instrumented outgoing or
incoming circuits.
