8.5 Contact Output Setting
8.5.1 Contact Output
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. Contact output 1 you can select open or closed contact when the contact is “operated”.
For contact output 2, contact is closed. The relay for contact output 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 contact output 2 is energized when the corresponding contact is
open and de-energized when that contact is closed.
