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.
