Introduction
The WCU310 series copper controllers are optoelectronic on-line analyzers that may
be used in variety of applications including electroless copper baths, microetch baths
and a number of other chemistries that contain more than 0.10 grams/liter (g/L) of
copper ions.
There are four relays that may be used as control outputs that are activated
simultaneously. The direction of control is selected via software. The outputs each
have timers associated with them, that may be used to track the volume of chemistry
added, or the time that the output has been on.
An optional 4-20 mA output that is proportional to the copper concentration is
available.
Either an immersible in-tank sensor or flow-through out-of-tank sensor may be
specified.
