TC01 Temperature Controller

The TC01 temperature controller is a microprocessor based, PID controller currently used in Sun's EC0X model temperature chambers. The TC01 controller has also been electrically and mechanically designed to be incorporated into temperature chambers manufactured by Delta Design, Inc. and Tenney Engineering Inc. or may also be easily installed into other temperature chambers and custom systems. The TC01 offers features and flexibility unmatched with analog controllers and was designed to be incorporated into modern computer systems or to stand alone as an intelligent local controller.
In the local mode the 16 key keyboard allows the operator to:

• set and read any of 10 SCAN temperatures
  set and read any of 10 SCAN times
  set number of cycles for SCAN mode
  read remaining time-at-temperature
  read chamber temperature
  start SCAN mode
  start single temperature/time mode
  reset controller

 

In addition, the temperature controller gives an audio and visual indication when time-at-temperature expires.

The remote mode of the TC01 allows all functions mentioned above to be executable via the IEEE-488 (GPIB) or RS232 bus. Audio and visual indications of time- at-temperature expiration is accompanied by an "interrupt" on the IEEE-488 bus and RS232 port. Local control can be enabled or disabled via IEEE-488 and/or RS232 commands. Two auxiliary outputs (TTL) are controlled by IEEE-488/RS232 to provide on/off control of external events (e.g.compressor). Local control can be enabled or disabled via IEEE-488/RS232.
An extra feature of the TC01 is its ability to act as a bidirectional IEEE-488 to RS232 interface. As such, commands are supported which allow ASCII characters to be input via the TC01 and IEEE-488 bus and sent out via the RS232 port, and vice-versa. This feature allows control and status of an RS232 compatible device or RS232 compatible user-installed hardware.

Installation of the TC01 into custom systems is easily accomplished via an 8 position terminal strip. Heat and cool outputs are switched
by triacs which in turn are controlled by the TC01 logic. See sample wiring diagram below. A retrofit kit is available for installation into Tenney Jr. systems.
