FA: 6 Chromalox 2002 Environmental Test Chamber Controllers
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=7626323597
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.

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™, 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.
Configuration
The units have configuration numbering as follows:
1. model 2002-11101 serial 0592123
2. model 2002-22101 serial 0492062
