The EDR-5000 distribution protection relay includes programmable

logic functions . Logic gates and timers may be defined and arranged

for customized applications . Programmable logic control functions

make the EDR-5000 relay ideally suited for main-tie-main and main

1/main 2 transfer schemes . Flash memory is used for the program

ming and all settings are stored in nonvolatile memory . The relay

allows for four preprogrammed setting groups which can be acti

vated through software or contact input .

Flash memory is used for the programming and all settings are

stored in nonvolatile memory . The relay allows for four prepro

grammed setting groups which can be activated through software,

the display or a contact input .

The EDR-5000 distribution protection relay has mass memory for

data storage and a real-time clock with 1 ms time resolution . The

relay will log 300 sequence of event records, 20 detailed trip logs,

minimum/maximum values, load profiles, breaker wear information

and oscillography data .

The EDR-5000 has eight programmable binary inputs, 2 normally

opened and 8 Form C heavy duty outputs and one form C signal

alarm relay . It can be powered from 19 Vdc to 300 Vdc or 40 Vac to

250 Vac auxiliary power
