Breaker Interface
Module (BIM)
The Breaker Interface Module (BIM) is a
panel mounted user interface device
that is mounted on the front of an elec-
trical assembly or at a remote location.
The BIM is used to access, configure,
test and display information for OPTIM
trip units and other devices. The BIM
consists of four display windows, eight
function buttons, 18 LEDs, and a graph-
ical time/current curve to provide
breaker status, operational information,
protection status and energy monitor-
ing. A 24 Vdc power supply is required
to provide power to the BIM. This is
supplied by the switchboard builder to
Eaton’s specifications. The BIM is a
member of Eaton’s Cutler-Hammer
PowerNet family of communicating
devices that connects OPTIM trip units,
Digitrip RMS 810/910 trip units and
energy sentinels as a subnetwork sys-
tem. The BIM can also be connected
to a main network via a PONI module
to PowerNet software.

Digitrip OPTIMizer
The Digitrip OPTIMizer is a hand-held
programmer that is used to access,
configure, test and display information
from OPTIM trip units. The OPTIMizer
plugs into the front of an OPTIM trip
unit via an eight-pin telephone jack
and is powered by a nine-volt battery
or the auxiliary power module. One
highlighted feature is the “Copy” and
“Download” commands. Setting up
multiple OPTIM trips can be finished in
minutes and with no errors. An Auxil-
iary Power Module connection provides
a trip test when control power is not
present at the breaker. The OPTIMizer
is supplied as a standard package to
include the programmer, the eight-pin
connection cord, battery and carrying
case. The Auxiliary Power Module
is optional.
Table 12-542. Digitrip OPTIMizer
Note: 24 Vdc Power Supply
A 24 Vdc power supply is required for all
Digitrip OPTIM trip units that are required to
communicate either on the main Eaton’s
Cutler-Hammer PowerNet network or as a
subnetwork to a BIM. The breaker’s load is
45 mA of current. Typically one power sup-
ply is required per switchboard and can pro-
vide control power to a BIM and the OPTIM
trip units. The 24 Vdc power supply should
be an “isolated high quality” power supply
with a “CE” label, and is normally provided
by the switchboard manufacturer to Eaton’s
recommendations.

Auxiliary Power Module
The Auxiliary Power Module is a
power supply requiring 120 Vac input
at 50 or 60 Hz that provides a 32 Vdc
output. The Auxiliary Power Module
provides control power for testing an
OPTIM trip unit when other means of
control power is not available or for
continuous OPTIMizer operation versus
temporary with a battery. The Auxiliary
Power Module connects into the top
of the Digitrip OPTIMizer via a keyed
receptacle. The main application for
the Auxiliary Power Module would
be for the testing of a stand-alone
non-communicating OPTIM breaker
that ordinarily would not have
control power.
Note: The OPTIMizer can work off of 32 Vdc
control power, although 24 Vdc is the stan-
dard on OPTIM breakers.
