Basler Electric IT-D, Isolation Transducer

Up to two IT-D Isolation Transducers can be used with each BE-11d DC

Power Protection System. An IT-D transducer electrically isolates the

BE1-11d from power parameters monitored by the system.

Each IT-D can monitor two parameters. Parameters monitored by the

IT-D include DC system voltages and current (measured through a

metering shunt). The output of each IT-D channel is a pulsed digital signal

with a frequency that is proportional to the monitored input signal.

These fiber optic channel outputs are provided to the BE1-11d DC Power

Protection System.

Two 30-foot fiber optic cables with fiber optic connectors are supplied with

every IT-D module ordered.

The BE1-11d DC Power Protection System provides flexible, reliable, and

economical dc power protection, control, monitoring, and measurement

functions. The capabilities of the BE1-11d make it well suited to provide

comprehensive dc power protection. The BE1-11d offers dc overcurrent,

over/undervoltage, rate of rise, power, and thermal overload protection

functions as well as breaker reclosing and RTD (Resistance Temperature

Detector) inputs with remote module. It offers breaker and trip-circuit

monitoring, and oscillography and sequential events recording.

Control features include virtual selector switches, circuit breaker control,

virtual lockout, and variable-mode timers.

System metering and status information are available at the BE1-11d front

panel and through the BE1-11d communication ports.

The system is suitable for mounting in OEM cubicle or retrofit switchgear

applications.

A front-panel USB port or optional rear Ethernet port enables local

communication between the BE1-11d and a PC operating with BESTCOMSPlus®

software. BESTCOMSPlus software simplifies the commissioning process by

providing a graphical interface for setting the BE1-11d and configuring a protection

and control scheme for your application. Through BESTCOMSPlus, all BE1-11d

settings and logic can be retained in a file for printing or uploading to other

BE1-11d protection systems. Oscillography and sequential events records can

be retrieved from a BE1-11d, viewed, and printed. Front-panel features include

a large, backlit alphanumeric display and LED indicators that display system

parameters, BE1-11d settings, and BE1-11d status. Pushbuttons enable navigation

through the display menu, changes to settings, resetting of targets (with password

access), and direct access to virtual switches.
