- Automatic
Database
Collect, store, and forward meter reports, targets, digital input status,
event reports, demand meter reports, and more. Use the optional Flash memory
for nonvolatile storage.
- Modbus® Slave, DNP3, and ASCII Serial Protocols
Provides easy-to-configure support for these popular serial protocols. SCADA
links, local Human Machine Interface (HMI), and dial-in modems can access
data from multiple IEDs or communicate directly with individual IEDs.
- Multi-Tasking,
Multi-User Communications Processor
Requests, receives, and configures information from connected Intelligent
Electronic Devices (IEDs) and communicates with master devices. Configure
any of the 16 rear ports as IED or master ports.
- Programmable
Logic Controller (PLC) Functions
Use Boolean and arithmetic operators to create logical schemes to produce
and forward information or to perform control. Reduce overall system costs
and improve system reliability by reducing the number of auxiliary devices.
- SEL
Binary Messages, Interleaved With ASCII Messages
A single bidirectional communications port carries ASCII commands and responses,
interleaved with SEL binary messages. SEL binary messages include SEL Fast
Meter messages for analog and digital SCADA information, SEL Fast Meter messages
to rapidly send control commands, and SEL Block Transfer messages for efficient
communications between communications processors. An example use of these
interleaved messages is that they allow an engineer to communicate with a
relay in ASCII through a dial-in port without impacting the real-time updates
from the relay to a SCADA system.
- IED
Communications
Powerful parsing, conversion, checksum calculation, and command response
setting features allow fast development of IED information retrieval and
control schemes. SEL provides "Job Done" examples that show you how to communicate
with many IEDs, using the native protocol commands and responses of each
IED.
- Time
Synchronization
Accepts time-code input from IRIG-B time source for its own internal clock
and redistributes it to IEDs. Or use the internal clock to generate IRIG-B
formatted time to the IEDs.

- Sixteen
additional optoisolated inputs and four programmable
output contacts.
- Two
MB Flash memory.
- Internal
modem for telephone connection.
- Rack-mount
or panel-mount hardware.
- Simplify,
improve the reliability, and reduce the total cost of
SCADA systems by using the SEL-2020 to collect and scale
meter data, and also collect targets, contact input status,
and fault location directly from relays. Use the contact
outputs of relays and other IEDs for control. Directly
support Modbus RTU Slave and DNP3 protocols for links
to RTUs or masters.
- Connect
IEDs that do not support Modbus to a Distributed Control
System (DCS). The communications processor provides faster
updates to the DCS than would a multidrop system because
it groups data for more efficient multiple-register or
block access. Arithmetic functions can change scaling,
calculate virtual analog inputs, and compare analog values
to thresholds. Use SELOGIC® control
equations to combine digital inputs to initiate and qualify
automatic control, or for interlocks.
- Support
local HMI on a PC or industrial computer using the SEL-2020
as a communications hub for gathering data from and directing
control commands to IEDs in the substation. Local event
report collection, settings management, and data archiving
may also be included in the local HMI.
- Set
the communications processor to detect critical conditions
and dial a pager. Send an ASCII message to an alphanumeric
pager.
- Use
the SEL-2020 as a hub to enable low-cost, point-to-point fiber-optic
links that isolate equipment from hazardous and damaging
ground potential rise; eliminate RFI, EMI, and communications
system ground loops; and allow longer signal paths than
possible with EIA-232 copper connections.
- Acquire
and forward information from relays and specialized equipment
monitoring devices to maintenance databases and expert
systems.
- Use SEL-5020
Settings Assistant Software to prepare settings
and communicate with the communications processor.
- Use
with SEL-5040 Power System Report
Manager Software to automatically gather relay event
reports and manage them with a database.
- Use SEL-5010
Relay Assistant Software to manage your relay settings.
