Wiring the Relay Contact

EDS-508 has two sets of relay output— relay 1 and relay 2. Each Relay Contact

consists of the two contacts of the terminal block on EDS-508’s top panel. You

may refer to the next section for detailed instructions on how to connect the

wires to the terminal block connector, and how to attach the terminal block

connector to the terminal block receptor.

In this section, we will explain the meaning of the two contacts used to connect

the Relay Contact.

FAULT: The two sets of relay contacts of the

6-pin terminal block connector are used to

detect user-configured events. The two wires

attached to the Fault contacts form an open

circuit when a user-configured event is

triggered. If a user-configured event does not

occur, the Fault circuit will be closed.
