Autotuning Benchtop Temperature Controller; Universal Input; 100-240V
Large dual-LED display—monitor set point and measured temperature values simultaneously
Ramp and soak features up to 56 programmable segments
Select reverse or direct control for heating or cooling
Program alarm set point to track the process
This autotuning benchtop controller monitors process temperature and set point values simultaneously on two large LED displays. The autotuning feature will automatically adjust the proportional band, rate, and reset once you have entered a set point. The controller can be manually set for customized control. For more complex processes the ramp and soak function provides for up to 56 discrete programmable segments. The controller also features universal input, status lights that indicate output and alarm conditions, programmable alarms, pattern end functions that allow for endless program runs, and a SPDT relay that is connected to an audible alarm with adjustable volume.
The built-in security system protects set point and alarm values from accidental or unauthorized changes. Nonvolatile memory retains parameters during power failures. Programming and remote monitoring of the controller can be done through the built-in RS-485 port that accepts MODBUS® ASCII/RTU communication protocol. Connect easily to any USB capable computer, by ordering the optional RS-485 to USB converter.
What's Included:
