The new CDCN-90 is specifically designed to monitor and control conductivity levels of aqueous solutions. The compact 14 DIN enclosure is NEMA 4X/IP65 rated and ideal for installations with limited space. Modular output cards can be customized to meet your requirements and are field installable. Output options include 4 to 20/0 to 20 mA, 0 to 5/0 to 10 Vdc card, 2 relay card and dual proportional relay card. Relays can be separately configured to operate as HI or LO alarms or proportional relays can be set for pulse rates from 1 to 120 pulses per minute.

All functions are easily accessed and programmed from the front keypad. The two-line LCD features a 4-1/2 digit main display and eight character alphanumeric line that provides calibration, setup, and operation instructions. Standard displays include conductivity and relay status information. Display options include °S, mS or ppm. In addition solution temperature can be quickly accessed with the touch of a button.
