SIPOD description
SIPOD is a remotely operated electro-
mechanical contactor device that is
attached to Siemens BQD molded case
circuit breaker. The purpose of a SIPOD is
to allow switching of a load, ON and OFF,
from a remote location or according
to a pre-arranged time schedule.
The SIPOD will connect to the load side of
the breaker using a conductor tab inserted
into the breaker load lug. The wiring to the
loads will be connected to the load lug of
the SIPOD, which is the same size as the
circuit breaker load lug.
The SIPOD communicates with the
controller in the P1 Lighting Panel via
a 4-wire connection to the data rail.
The 4 wire connections to the data
rail are:
•
A common line
•
A 24 volt power for the electronics and
operation of the solenoid
•
A selector line used by the I/O Controller
Board to select a SIPOD
•
A communication line
