Introduction
Getting Started
General Description
The SEL-DTA2 serves as an extension to the SEL family of digital relays.
New faults are automatically captured, stored in a 30-event fault history, and
displayed, effectively eliminating the need for a separate automatic message
output device. The SEL-DTA2 also provides access to metering and relay
status information. A set of eight voltage outputs and eight current outputs
presents fault and meter data to monitor and control equipment.
The SEL-DTA2 provides two communications ports. Port 1 may be used for
changing the analog output scaling and other settings, while Port 2 links to the
relay for communications. Refer to
Relay Compatibility on page A.2 in
Appendix A: Firmware Versions and Relay Compatibility for a list of
compatible SEL devices.
