TC10 CONTROLLER
The TC10 controller is a user friendly, flexible and precise PID controller that is used in the EC1x, EC1.3W and EC1xHA model temperature chambers.
The TC10 controller has an easy to use, menu driven interface with a 2-line by 16 character, backlit LCD. Temperature testing applications are facilitated by simple
commands defining individual temperature segments. The controller can store up to 10 temperature profiles and up to 100 temperature segments into non-volatile memory and may be entered from the keyboard or uploaded remotely via the built-in GPIB or RS232/422 remote interfaces.Programming the controller to carry out multiple segments
automatically is simplified by a BASIC-like command set
consisting of integer variables, nested FOR/NEXT loops, GOSUB
subroutine calls and IN/OUT instructions for communication
with the various I/O ports.
Three menu-driven setup modes are available to tailor the
controller to virtually any application. The CAL, SDEF and
SINT menus respectively, permit selection and calibration of
both chamber and user probes and modification of default and
interrupt configuration parameters defining, for example, GPIB
address, D/A output configuration, alarm function and loudness,
baud rate and timeout interrupts. The controller may also be configured to operate cooling valve options available on EC1x models such as LN2 Auto Line Purge, 2 or 3 tank LN2/LCO2 and LN2 redundant valve.
The TC10 controller has 2 probe channels - the chamber probe, which senses chamber air temperature and the user probe which may be attached to the DUT - and either the chamber, the user or a combination of the two probes may be used for control. Both probes are electrically isolated to 250 volts and can be an RTD or J/K thermocouple. An additional 2 read-only probes (K thermocouple only) may be installed upon request to be used for monitoring product temperature. An expanded I/O interface allows the user to install custom test fixturing and accessories. The provision of analog input and output channels, auxiliary relay control, a user digital parallel port empower the fullest control and monitoring of all aspects of the application.
