AM16/32 Relay Analog Multiplexer
35
Several enclosures are available for purchase through CSI (models
AM-ENC, ENC 12/14, and ENC 16/18). They offer a degree of
protection against dust, spraying water, oil, falling dirt, or dripping,
noncorrosive liquids. These enclosures contain a mounting plate with
1-inch hole grid suitable for mounting the AM16/32. The enclosures
have a cable bushing (AM-ENC has two) to accommodate the sensor
lines. These standard enclosures are rain-tight, but not water-proof.
The enclosure lids are gasketed. The screws on the outside of the
enclosure should be tightened to form a restrictive seal. In high
humidity environments, user supplied foam, putty, or similar material
helps to reduce the passage of moisture into the enclosure via cable
conduits.
8.1 Mounting Tabs
The AM16/32 has mounting tabs allowing attachment by four screws.
See Figure 21 dimensions.

FIGURE 21. Mounting Tab Hole Pattern
U-bolts are provided with enclosure to attach to a 1.25 inch (32 mm)
diameter pipe. An enclosure may also be lag-bolted to a wall or other
flat surface.
8.2 Controlling Humidity
The multiplexer is susceptible to corrosion in high relative humidity.
Desiccant packs are available from CSI and should be used inside the
enclosure to remove water vapor.
Air movement should not be restricted through an
enclosure containing batteries that may produce
explosive or noxious gases (e.g., lead-acid
batteries).
