The OMEGA® CN2120 Ramp/Soak Controller is a fully functional controller with flexibility to meet many demanding control applications. The controller has many standard and special features that allow precise programming for any profile application.
Program
The 200 segments can be used in up to 90 programs. These programs can be linked together or run separately. For each of the programs, it is possible to:
• Use up to 99 segments
• Set program repetitions
• At the end of program, either turn on an "end of program" digital output, turn off the control outputs, set the control output to a set value, or use the last set point of the program for control.
• Set up to 14 events
• Choose one of 5 PID groups/segment
• Choose one of 10 Wait bands/segment
Real Time Clock Option: Allows for auto start program at specific time and on specific days.
Special Control Features
The CN2120 provides special programming features that will improve the control for some applications. The CN2120 has the capability of splitting the control output between 2 outputs in the "Split Range" feature. Another program feature allows use with quick opening and equal percentage type valves.
Digital Inputs
Three Digital inputs are standard on the CN2120 with options for up to 8 additional inputs. These inputs can be programmed to:
• Select between Run/Hold
• Abort a program
• Select a program
• Auto/manual selection
• Set output limit
• Reset alarm
• Reverse or direct control action
Digital Outputs
Outputs 2, 3 and 4 can be used as digital outputs. In addition, options are available for 5 or 10 additional outputs. These outputs can be programmed as:
• Break event
• Timer event
• End of cycle annunciator
• Program in Run, Hold or Wait State
• Controller in manual or auto state
• Error annunciation
