The new CDCN-90A is specifically designed to monitor and control conductivity levels of aqueous solutions. The compact 1 /4 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 µS, mS or ppm. In addition solution temperature can be quickly accessed with the touch of a button.
