A150 Desiccated Case

It is not recommended to insert more than one wire into each

connection on the terminal block. If it is necessary to combine

wires, use the 5-position lever nut to combine the wires, and then

insert the lead wire from the lever nut into the terminal block.

NOTE

When used with a CWS900, the sensor can be used with sensors measuring

analog voltages, frequency, and pulse. The CWS900 can also provide

excitation voltage to a sensor through the A150.

2. Physical Description

The A150 has an 80 mm x 82 mm x 55 mm chassis. Four screws secure the lid

to the rest of the unit. A terminal block is mounted inside the chassis. A small

vent is located on the bottom of the chassis. The vent is protected by a GORE

filter, which prevents moisture and contaminants from entering the unit while

equalizing the interior air pressure to the current atmospheric pressure.

A mounting bracket is attached to the bottom of the chassis. The bracket is

used to fasten the A150 inside an enclosure or, with the included Velcro

strap,

to another location of the user’s choosing.
