Field expandable hardware and software Easy to add/replace module. Software configurable based on installed modules.
Dual RTD and dual Analog Input Module Includes two RTDs and two analog inputs. RTD selectable for 100, 1000, 2500, and DIN 100 Ohms. Analog inputs software configured for temperature, pressure, density, specific gravity or flow. Accuracy: 0.025%. Resolution: 12 bit. Range: 4-20mA, or 1-5V. Overvoltage, overcurrent protected.
Alarms Multiple visual/audio alarms. HI/LO, HI/HI, LO/LO.
Batch, BTU Single/Dual Stage batch operations. Count UP/DOWN. BTU functions (Cooling, Heating, Heat/Cool Auto Switch).
Analog Output Module Flow compensation and calculation methods Includes analog output. 12 bit true D/A. Selectable 4-20mA, 1-5V. Current sourcing or powered from external power supply. 20 point flow linearization. Multiple flowmeter calibration tables(2) including UVC. (2 channels must be analog)
Security Features Dual Relay Module Audit Trails with Time/Date/ID stamping for each change of configuration parameter. Double storage of process variables. Includes two SPDT relays. Vmax 250 VAC, Imax 5A or Vmax 125 VAC, Imax 10A. Software configurable function: flow, temperature, pressure, density alarms (high and low). Optional miniature reed relays available. Hardware Specification Nova-Flow construction allows for full flexibility in selecting flow computer functions. The base Nova-Flow unit provides for one flowmeter input, and 8 digital I/O lines. Seven I/O lines can be configured as Input or Output. The unit has 8 expansion slots for optional I/O modules. Almost any combination of modules can be selected to meet customers individual needs.
