If S1 is down, the 3-channel of this switch is non-functional; the 4-channel still functions normally.
4.11 Multi-Variable Sensor Input/Output (MVS I/O)
The Multi-Variable Sensor Input/Output (MVS I/O) module provides an
interface to a sensor that provides differential pressure, static pressure,
and temperature inputs for the ROC800 for orifice flow calculation.
MVS I/O or
MVS Module?
Remote Automation Solutions offers both an MVS and an MVS I/O
module. These modules have identical functions and differ only by
where you can place them in the ROC800.
You can place the MVS module (shown on the
left
side of
Figure 4-26
)
only
in the first
three
slots of a ROC800. The enhanced design of the
MVS I/O module (shown on the
right
side of
Figure 4-26
) enables you
to place it in
any
available slot on the ROC800. In most other ways the
two modules are identical.
