Reference Data
Materials of construction for optional junction box
Weight
A.2.3 Environmental ratings
NEMA Type 4X and IP66 with optional junction box. JX3 Explosion-proof enclosure rated to -4 °F
(-20 °C).
A.3 Function blocks
A.3.1 Analog input (AI)
Processes the measurement and makes it available on the fieldbus segment.
Allows filtering, alarming, and engineering unit changes.
A.3.2 Input selector (ISEL)
Used to select between inputs and generate an output using specific selection
strategies such as minimum, maximum, midpoint, or average temperature.
Since the temperature value always contains the measurement status, this block allows
the selection to be restricted to the first “good” measurement.
A.3.3 Multiple analog input block (MAI)
The MAI block allows the eight AI blocks to be multiplexed together so they serve as
one function block on the H1 segment, resulting in greater network efficiency.
