Output Contact

Mechanical relays provide contact outputs. Be sure to observe relay contact ratings. (For
details, see Section 2.1, General Specifications.) The operation modes of each contact
output are as follows. Output contact 1 enables the selection of an open or closed
contact when the contact is "operated". For output contact 2, contact remains 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.
