Breaker Interface Module
General Description
Eaton’s Cutler-Hammer Breaker
Interface Module is a panel-mounted
device which performs the following
functions:
■ Monitors and displays parameters
(right) from any combination of
Digitrip RMS 810, 910, Digitrip 1150
when set up to communicate as
a 910 and Digitrip OPTIM Trip
Units, Energy Sentinels and Power
Sentinels, supporting as many as
50 of these devices up to 10,000 feet
(3,048 m) away.
■ Communicates the information
from these protective and energy
monitoring devices over a Cutler-
Hammer INCOM network.
■ Continuously monitors breaker’s
recording and time stamping trip
events along with approximate fault
currents. Events are logged into
non-volatile RAM.
Parameters Displayed
■ Phase current
■ Energy
■ Present demand watts
■ Peak demand watts
■ Average demand current
■ Cause and magnitude of trip
■ Trip history
■ % Total Harmonic Distortion (THD)
for each phase
■ % Harmonic Content for each phase
(1st – 27th harmonic)
■ Custom circuit description
Note: The Breaker Interface Module
displays only a portion of the information
it receives from the Digitrip RMS 910
and Power Sentinels. The balance of the
information (such as waveform analysis
and power factor) can be passed through
the unit to a master computer, where it
can be viewed.
Communications
A PONI card can be easily field-
mounted to the back of the Breaker
Interface Module, enabling the unit
to pass the information from its
subnetwork to a remote master
control unit up to 10,000 feet (3,048 m)
away. No reprogramming of the unit
is required when the IPONI is added.
The Breaker Interface Module can
be mounted directly on the assembly
or at a remote location and can be
used to access, configure and display
information from OPTIM Trip Units.
An operator can use the Breaker
Interface Module to:
■ Complete initial system setup:
❑ Select system frequency
(50/60 Hz)
❑ Set password
■ Configure the system:
❑ Change time-current set points
for Digitrip OPTIM breakers
❑ Select protection options
❑ Select alarm levels
■ Display information:
❑ Breaker information
❑ Time-current set points
❑ Metered values
❑ Trip event information
■ Test trip unit performance:
❑ Phase and ground
❑ Trip/no trip
■ Expanded energy monitoring:
❑ Set addresses for group energy
monitoring
❑ Group energy readings
■ Local and remote indication:
❑ Remote indication/alarming
❑ Breaker status LED indication
■ Expanded communications.
Communicate with:
❑ OPTIM Trip Units
❑ Digitrip RMS 810 and 910
(1150 as 910) Trip Units
❑ IQ Energy Sentinels
❑ IQ Power Sentinel
❑ A total of 50 devices
Password Protection
A user-defined password is included
for added security when changing
settings or performing breaker tests.
Non-Volatile Memory
The programmed functions, addresses
and circuit descriptions are stored in
non-volatile memory.
External Power
A 24 Vdc supply is required for
the BIMII. (No external power supply
is required for the PONI Card.) A 120
or 240 Vac supply is required for
the BIMPS.
Rear Access Area
All wiring connections to the Breaker
Interface Module are made at the
chassis’ rear and include:
■ Relay connection for “alarm”
condition, “high load” condition,
“peak exceed” for device or group,
and watthour pulse
■ Initiator
■ 24 Vdc input — BIMII
■ 120 or 240 Vac input — BIMPS
■ DIP switches for selecting an
operating mode
■ Three-contact connector with
subnetwork
■ Connector for PONI card for remote
communications Local Display Units
