PHCN-37 Series Microprocessor-Based pH Controller with Automatic Temperature Compensation This microprocessor-based family of pH, ORP and pH/ORP panel mounted controller is designed for a wide variety of environmental monitoring applications. The units feature automatic or manual temperature compensation of pH, two 5 A mechanical relays and a choice of a scalable 4 to 20 mA, or 0 to 20 mA control or recording output or a 0 to 10V output. For ease of operation all calibration and parameter setpoints are selectable through the front keypad. The PHCN/ORCN/ OPCN-37 can be interfaced with a variety of pH and ORP electrodes. Specifications ORP Range: ORCN-37: ±2 Vdc OPCN-37: ±620 mV Resolution: 0.1, 1 mV Accuracy: 0.1 mV @ 25°C Decimal Point: 2 position auto ranging pH and Temperature Range: 0 to 14.00 pH; 0 to 100°C (32 to 212°F) Resolution: 0.01 pH, 0.1°C Calibration pH: 2 or 3 point Accuracy: ±0.03 pH; ±0.5°C Common Specifications Display: 4-digit, LED, 13.7 mm (0.54") Relays: Dual SPDT (form C) 5 A @ 240 Vac, mechanical relay. Programmable deadband hysteresis around setpoints. Output: 4 to 20 mA, 0 to 20 mA or 0 to 10V (scalable) software selectable Input Impedance: >10 12 Ω Temperature Compensation: Manual or Automatic, 0 to 100°C using Pt 100 Ω or Pt 1000 Ω RTD Comes complete with operator’s manual. To order with isolated analog output, add suffix “-AI” to model number for additional cost. To order with 10 to 32 Vdc power, add suffix “-DC10/32” to model number for additional cost. To order with 26 to 56 Vac power, add suffix “-DC26/56” to model number for additional cost. Ordering Examples: PHCN-37 microprocessor-based pH controller.
