details, consult the 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, output contact 2 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.
