16 digit alpha-numeric LED display for fault report,
metering values, alarm messages, setting parameters, etc.
keypad includes 20 keys for user friendly
local interface with the DGP
dual color LED indicates relay status
RS232 port facilitates connection of lap-top PC
MODULES
System Processor (SSP),
Analog Interface (ANI),
Data Acquisition (DAP), &
Digital Signal Processor
(DSP) modules are plug-in
type for ease of maintenance
and trouble-shooting.
DIGITAL INPUT & TARGET
MODULE (DIT) LED targets
indicate ALL the fuctions
that operated during a
trip event
MAGNETIC MODULES
(MGM) Two identical
modules contain CT's, VT's,
output relays, etc. and are
interchangeable.
OPTIONAL TEST BLOCKS
facilitate injection of
analog input signals and
monitoring of DGP outputs
for test purpose without
disturbing field wiring.
POWER SUPPLY MODULES
are located behind the
cover plate. Module PS2
is optional
RS232 PLUG (PL-1)
provides connection to modem
for remote communications
or an interface to station
integration system.
OPTIONAL SERIAL PORT (PL-2)
Can be used to connect a
printer for automatic/manual
printout of data or a Contact
Expansion Unit DEC1000.
OPTIONAL PLUG (PL-3)
Available for IRIG-B signal input
to synchronize the DGP internal
clock to a common reference
clock e.g. GPS receiver.
