Secure Cellular Connectivity

Key Features and Benefits

The SEL-3061 Cellular Router provides secure wireless connectivity to a variety of critical infrastructure devices

through the use of cellular networks. With a high data rate, the SEL-3061 serves as a communications backhaul for sys-

tems that need communications links to centralized locations. The router supports 4G LTE and 3G cellular technologies.

➤Multiple Carrier Support. Supports AT&T, Verizon, T-Mobile, Rogers, Bell, and Telus networks.

➤Strong Secure Communication. Offers as many as five concurrent IPsec VPN connections. X.509 certificates

ensure strong authentication with third-party validation.

➤User-Based Accounts with Centralized User-Based Authentication. Provides separate role-based authorization

levels for configuration, maintenance, and usage. Supports Remote Authentication Dial-In User Service

(RADIUS).

➤Syslog. Logs system events for alerts in a consistent fashion for both local and centralized collection.

➤Network Management. Supports SNMP reads and traps for versions v1, v2c, and v3.

➤Application Versatility. Serial and Ethernet ports enable communications with a variety of end devices.

➤Dual-Mode Operation. Gives flexibility of operating as a router or bridge.

➤Stateful Packet Inspection (SPI) Firewall and IP Defense. Dynamic packet filtering prevents unauthorized

traffic from entering your private network. Log all successful or blocked connections to the firewall. IP Defense

mitigates the effects of denial-of-service and brute force attacks.

Product Overview

Features

Secure Communication Over

Cellular Network

The SEL-3061 offers comprehensive security methods

that include VPN, IPsec, SPI firewall, and media access

control (MAC) address filtering to ensure the confidenti-

ality and integrity of data communications over a cellular

network. The SEL-3061 uses RADIUS and user account

privileges to grant access to the device.

Device Management

The SEL-3061 simplifies device monitoring and man-

agement via the web interface of the router including

over-the-air settings changes and firmware upgrades.

Ubiquitous Connectivity

The SEL-3061 supports 4G LTE and 3G cellular technol-

ogy and uses cellular networks to provide wireless con-

nectivity for a variety of critical infrastructure devices.

Reporting and Alarms

The SEL-3061 uses the Syslog format to log events. The

router maintains an internal record of as many as 30,000

event logs in nonvolatile memory that can be down-

loaded into a CSV file. The Syslog supports two Syslog

servers. Notifications and alarms can be triggered by the

events and sent by using either SNMP, email, or short

message service (SMS) messages. The SEL-3061 has an

output alarm contact that pulses for major and minor

alarms.

The SEL-3061 supports SNMP to provide state informa-

tion and notifications (traps) for events that indicate the

device health and status. The SEL-3061 allows Manage-

ment Information Base (MIB) files in zip format to be

downloaded to provide information about data and traps

available via SNMP.

Application Examples

The SEL-3061 serves as the communications link for

field devices or backhaul communications device. For

electric utilities, the SEL-3061 provides connectivity to

devices such as recloser controls, motor-operated

switches, capacitor banks, voltage regulators, meters, and

other IEDs. The combination of serial and Ethernet ports

on the SEL-3061, along with secure tunneling, provides

application flexibility and makes installation easy with-

out sacrificing security.

SCADA

The SEL-3061 provides the communications link to

aggregate data from field devices and forwards it to

SCADA systems and HMIs. The SEL-3061 can be used

in data acquisition and slow-to-medium speed control

applications. SCADA includes analog and discrete I/O

monitoring and metering. The SCADA control includes

set-point changes of processes and operations of discrete

I/Os. Field devices connect directly to either the Ethernet

port or serial port on the SEL-3061. The SEL-3061 links

these devices to a SCADA system via cellular WAN con-

nections and allows the SCADA to poll each device by

using DNP3 over TCP/IP and Modbus TCP/IP.

Engineering Access

The SEL-3061 allows users to access IEDs to view and

modify settings and download oscillographic event

reports through VPNs.

Distributed Data Acquisition

Modern automation systems can be distributed over a

large geographical area. These automation systems mon-

itor and process input signals, execute logic, and enable

or disable outputs. In some instances, it is necessary to

perform data acquisition on the status or value of the

connected I/O. A distributed data acquisition system uses

an automation controller as the data concentrator and a

computer as the SCADA host. The system uses remote,

discrete, and analog I/Os. As shown in Figure 3, a single

SEL-3061 at each site both provides the connectivity

between these remote I/Os with the automation control-

ler and backhauls the collected data to the SCADA com-

puter.

Distribution Automation

The SEL-3061 provides cellular connectivity to remotely

monitor and control recloser controls and sectionalizers

for distribution power systems, as shown in Figure 4. In

cases where customers rely on communications schemes

for power restoration, the SEL-3061 provides the con-

nectivity. The main difference between the distribution

automation (DA) systems that use line-of-sight radios

and DA systems that use an SEL-3061 is that the

SEL-3061 and DA can be installed at any IED location

that has cellular coverage. The DA controller polls data

from each recloser control for monitoring and sends con-

trol signals through the WAN and the SEL-3061.

SEL-FLT/SEL-FL R Network Backhaul

The SEL-FLT and SEL-FLR Fault and Load Transmitter

and Receiver System provides wide-area load monitoring

and fault location from line-powered SEL-FLT devices.

The SEL-FLR collects load data and fault information

from the SEL-FLT devices and sends the collected data

to an Operation Management System (OMS) or Energy

Management System (EMS) via a WAN. The SEL-3061

provides the communications link between the OMS and

the SEL-FLR. When connected to the SEL-FLR the

SEL-3061 provides wireless connectivity for the

SEL-FLT/SEL-FLR networks, as illustrated in Figure 5.

Distributed Generation

The SEL-3061 provides the connectivity to remotely

monitor and control relays, devices, and equipment at

distributed generation (DG) sites. In most applications,

an automation controller interfaces with devices located

inside the DG facility. The SEL-3061 can be connected

to the controller to provide backhaul connectivity for

devices located at the DG sites. The SEL-3061 is suitable

for monitoring and non-protection speed control of the

DG site.

Voltage Regulators

Voltage regulators installed outside the substation use the

SEL-3061 to report their status and receive control com-

mands from either a controller or the SCADA system.

Connect the voltage regulator to the SEL-3061 by using

either the serial or Ethernet interface.

Capacitor Bank Controls

The SEL-3061 provides communication for remote mon-

itoring and automated or manual control of capacitor

banks.

Pump Automation Controls

Monitor and control critical infrastructure, such as water

and wastewater pumps, by using the SEL-3061 to pro-

vide remote access to SEL-2411P Pump Automation

Controllers. During both routine operations and natural

disasters, the cellular network provides a reliable path

from a control center to the field. Use an Ethernet switch

to connect more than one controller to a single

SEL-3061.

Network Backhaul

A radio or Advanced Metering Infrastructure (AMI) net-

work usually has an access point that concentrates data

from remote endpoints. The access point is usually con-

nected to a WAN or another wireless network. The

SEL-3061 can be used as the link between the access

point and the WAN or the wireless network by providing

backhaul for these networks.
