8.5 Output Contact Setup
8.5.1 Output Contact
Mechanical relays provide contact outputs. Be sure to observe relay contact ratings. (For details, see
Section 2.1, "General Specifications.") 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.
