Product Description
TEC-8A-24V-PID-HC is improved digital temperature controller. The present
version can heat and cool without changing any jumpers. The controller is available
in two versions of the program: Basic and Advanced. Beyond the basic functionality,
Advanced version offers the possibility to set various parameters of the controller
using UART.
TEC-8A-24V-PID-HC has an open collector output which allows to use it as a
signal for other devices. Open collector will indicate when the measured
temperature is out of the Tmin/Tmax range. In addition to open collector, warning
LED will indicate this also. The indication LEDs show heating or cooling activity.
Also, the dimensions of the PCB are smaller and mounting holes were added.
You can use UART to read the temperature setpoint, actual temperature and
PID parameters values. To read accurately the value of the temperature use a
thermistor with BETA value of 3950 for basic and advanced versions and for
advanced ±100°C version you need a P0K1.202.3FW.B.007 thermistor.
Its small size, simplicity of regulation and versatility make it widely used in
many areas. It is dedicated to work with 12 V thermocouples (Peltier modules) yet
it does well with all modules whose supply voltage falls in the range of 5 to 24 V.
With the use of four trimmers, the temperature setpoint as well as values of
the PID controller parameters can be set. The controller operates in PWM mode
(Pulse Width Modulation) and can control currents of up to 8 A. For the temperature
sensor, it uses a standard 10k NTC B=3950 thermistor for basic and advanced
version and for advanced ±100°C version it uses a P0K1.202.3FW.B.007
thermistor. By default, the temperature setpoint is set to 25 degrees Celsius.
Due to the possibility to set the parameters of a PID controller, the driver can
be adapted to almost any system. Depending on the inertia of the system, properly
adjusted driver is able to maintain the desired temperature with an accuracy better
than ±0.05°C.
The current flowing through the Peltier cell depends on the supply voltage
used. Most of the common modules should be supplied with the voltage of 5 to 24V,
and the maximum current that flows through them is defined by a cell symbol.
The driver is working in TTL 3.3V standard.
