 CvL's
engineer's went tot work and came up with a compact, NEMA 4 control panel that
uses (2) Watlow 988 controllers with (1) TrenView electronic recorder. The first
988 controller use an RTD input for temperature, while the second receives
a 4-20 mA signal from a relative humidity transmitter Both controllers
retransmit their signal in to the TrendView recorder. The TrendView was selected
because of its ability to record dataright to floppy disk and because of its
data protection.
