• Save Time in the Field
  Set the Data Courier in the office so field personnel can easily accomplish tasks using pushbuttons, instead of navigating through a laptop operating system, file trees, and application software.
  Quickly load new firmware, send or retrieve settings, and gather reports. Start data transfers without waiting up to 7 minutes for a laptop to start up. Configure the Data Courier in the office to minimize time spent at remote sites.
• Apply Easily
  Go everywhere with the portable battery-powered device. At your desk, use SEL-5891 Data Courier Configuration Software to easily configure pushbuttons and store associated settings or firmware. In the field, complete tasks with simple button sequences.
• Prevent Misuse
  Lock out unauthorized use with a PIN in case of loss or theft. Device access passwords are protected in memory with encryption.

• Gather event reports from relays at sites that do not have remote communications links. Event reports provide important information to evaluate relay operations and analyze power system problems.
• Load new firmware into relays to activate new features (for example, synchrophasors) or to upgrade to the newest firmware version.
• Transfer new settings into relays to support expansion of the power system and to activate new capabilities. Retrieve settings to check that field device settings match approved settings files as a part of protection configuration control or audits.
