FA: 6 Chromalox 2002 Environmental Test Chamber Controllers
Text from the auction listing:
These were known to be working units pulled from industrial equipment and replaced by more recent Watlow units during a corporate upgrade but they are sold as-is due to age and since we do not repair these units.
6 units are available, and two of them were calibrated as recently as October of 2004.See manufacturer's full product info (similar to this listing) online at:
An original manual will accompany the units.
2002 1/4 DIN Heat/Cool Temperature Controller- PID or ON/OFF Control
- Dual PID Outputs, Dual Display
- Four Types Plug-in Output Modules for Heat or Cool Output
- J, K, E, T, R, N, S Thermocouples, RTD and Analog Inputs
- Self-Tuning
- 16 Interval Ramp/Soak Program
Description
The Chromalox 2002 temperature and process controller has unlimited applications flexibility, providing heating and cooling control for a broad range of heat/cool applications, as well as other applications requiring bidirectional, dual output PID control.
Features
- Two programmable PID outputs, heat (Output #1) and cool (Output #2). Field selectable Proportional, PID or ON/OFF control modes may be programmed for each output.
- Heat/Cool Ratio (gain ratio) and Offset adjustment optimize heat/cool performance, balancing between heating and cooling control and yielding stable process control.
- Expertly engineered Cold Start and Adaptive self-tuning algorithms determine the optimum PID control parameters, eliminat- ing tedious and time-consuming start-ups.
- One Alarm and Event Relay Output may be selected as normally-energized or normally- de-energized with upper and lower limits.
- Digital Communications option accommodates RS-232, RS-422 and RS-485 serial interfaces and operates using a simple ASCII data terminal or specialized software on a computer. ChromaSoft=99, Chromalox's remote operator interface software, communicates with up to 255 controllers in any combination.
- Digital Communications Interface also operates without a software program. Using a standard ASCII data terminal or personal computer, any parameter that can be accessed from the controller's front panel can be changed or adjusted. Automatic Data Logging provides a printout and/or display of up to 10 different control parameters and variables.
- Optional Process Signal Output and Remote Setpoint features allow the
2002 to operate with other system peripherals.- 16 Interval Ramp/Soak Program includes HOLD, STANDBY and RUN selections, 16 separate setpoints plus a Standby setpoint, Guaranteed Soak, individually timed intervals, and the option of assigning the Alarm Relay as an Event Output.
