CDCN-91 Series Specifications General Compatible Sensors: CDCE-90 Series standard conductivity/resistivity sensors Operating Range: Conductivity: 0.055 to 400,000 µS/cm Resistivity: 10 kΩ/cm to 18.26 MΩ/cm (0.055 to 100 µS/cm) TDS: 0.001 to 999999 ppm or ppb (display limit) Temperature: PT1000: -25 to 120°C (-13 to 248°F) Accuracy: Conductivity/Resistivity: ±2% of reading Temperature: ±0.5°C Power Requirements: 100 to 240 Vac: ±10%, 50 to 60 Hz, 20 VA 11 to 24 Vdc: ±10% reg., 0.5A max Display: Alphanumeric 2 x 16 LCD Contrast: User selected, 5 levels Update rate: 1.5 seconds Current Outputs: (3 each) 4 to 20 mA, isolated, fully adjustable and reversible Max Loop Impedance: 150 Ω @ 12V, 450 Ω @ 18V, 750 Ω @ 24V Update Rate: Approx. 100 mS Accuracy: ±0.03 mA @ 25°C, 24 Vdc Open Collector Outputs: (2 each) Isolated, 50 mA sink or source, 30 Vdc max pull-up voltage Operational Settings: Hi, Lo, USP, Pulse, Off Hysteresis: User adjustable Time Delay: 0 to 6400 seconds Maximum Pulse Rate: 400 pulses/minute Alarm Contacts: (up to 4 each) SPDT Relays Maximum Voltage Ratings: 5A @ 30 Vdc or 5A @ 250 Vac Operational Settings: Hi, Lo, USP, Pulse, Off ELECTRONICS The CDCN-91 Series dual channel conductivity/resistivity controller is a two-channel input device equipped with three scalable 4 to 20 mA outputs and four programmable relays. A selector switch activates two open collector outputs in place of two of the relays for extraordinary output versatility. Dual input and advanced control capability, including percent rejection, difference and ratio calculations, together with the CDCE-91 Series conductivity sensors listed below, form the perfect measurement and control system for water treatment applications and more. Two versions are available: one accepts AC line-voltage, the other low voltage DC for power. The four-button keypad arrangement with intuitive software design is user-friendly, and the NEMA 4X (IP65) integrity of the front panel can be extended to the entire enclosure by using the optional rear cover kit.
