Multi-zone: PID, data acquisition supports ramp/soak control
Modular controller provides multi-zone PID control, data acquisition and I/O modules for PC, DCS or PLC control systems, and integrates data logging and advanced alarm management.
York, PA — Red Lion Controls Inc. announced that its Modular Controller Series PID modules now support ramp/soak control. The company says the modules provide multi-zone PID control, data acquisition and I/O for PC, DCS or PLC control systems, while integrating data logging and advanced alarm management. With the latest update to the company’s Crimson 2.0 programming software, users can integrate multi-segment temperature profiling for complex processes in the autoclave, heat-treating, food and chemical industries.
Ramp/soak functionality consists of a profile, or succession of setpoint ramp and soak periods. The company says the profile can support up to 30 segments, with each segment defined by a setpoint and a time, allowing users to set a temperature range and period of time in which the range will be maintained. The dedicated single and dual PID modules each manage ramp/soak control individually, maintaining independence for each loop and allowing hot-swappable replacement for reduced downtime. Plus, advanced modes are available for critical control requirements, such as guaranteed soak times and ramp rates.
The controller is said to feature a built-in protocol conversion facility and multiple-protocol Ethernet port that allows even the most complex PID, data-acquisition or I/O systems to be configured “in just minutes.”
