4.4.3 Input/Output connections
1. Analog output – Iout 0 is used for the current signals of the measurement. Other analog
outputs can be freely linked to different parameters like measurement, temperature – refer
to the section entitled User Setup on page 79 for details.
2. Relays – Rel 8 is linked to the system alarm and is normally energized. Rel 7 is linked to
the warning alarm. The position of the contact represented on the diagram above
corresponds to a state when the relay is not energized. See Alarms on page 84 for more
information on the relays.
3. Logical inputs (5) – four inputs allow sample measurement to be by-passed on selected
channels by providing 1 dry circuit for each selected channel, which will then be closed to
by-pass channel measurement until that circuit is re-opened. The fifth input is to launch the
remote calibration (same principle as sample measurement by-pass).
4. Close the I/O box.
