8.4 Output Contact Setup
8.4.1 Output Contact
Mechanical relays provide contact outputs. Be sure to observe relay contact ratings. (For details,
see Section 2.1, “General Specications.”) The following sets forth the operation mode of each
contact output. Output contact 1 you can select open or closed contact when the contact is
“operated”. For output contact 2, contact is closed. The relay for output contact 1 is energized
when its contacts are closed and vice versa. Accordingly, when no power is supplied to the
equipment, those contacts remain open. In addition, the relay for output contact 2 is energized
when the corresponding contact is open and de-energized when that contact is closed.
