Terminal layouts and connection diagrams

BIO-Tester follows the same terminal description as in REX640 protection relays. It
is equipped with test switches and indication LEDs for power supply and BIO
modules. Using pre-wired connectors, test switches can be wired to the protection
relay's binary input terminals to simulate process signals connected to the protection
relay, and indication LEDs can be wired to a protection relay' binary output terminal
to indicate the binary output status.
