Equipment Validation—Verify that your equipment is working properly with the SEL-4388. The LCD shows addressing and communications parameters as well as the detected data rate. The LEDs display the current state of all Receive and Transmit Mirrored Bits.
Field Testing—The SEL-4388 is ideally suited for onsite relay testing. This portable, battery-powered tester goes everywhere. Power is supplied by two AAA batteries or the external 4–18 Vdc power jack.
Commissioning—Save valuable time using the SEL-4388 for commissioning. Streamline the setup process, and verify that the Mirrored Bits implementation and communications circuits are working properly.
Training Aid—Help personnel new to Mirrored Bits communications learn by using the SEL-4388 to interact directly with a relay. The user interface is simple and provides instant visual feedback.
Quickly test communications by automatically detecting and displaying SEL Mirrored Bits information, addresses, and data rate, easily identify cable usage, and use pushbuttons to simulate inputs to force Transmit Mirrored Bits for testing.
Streamline commissioning by easily verifying the Mirrored Bits implementation and communications circuits.
Portable battery-powered tester goes everywhere. Power is supplied by two AAA batteries or through the external power jack.
