SEL-3061 Data Sheet

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
