Terminal Block
Wire your thermoelectric module and sensor via
the 12-contact screw terminal connector. Connect
the external setpoint voltage input here, also. Other
signals are available on the PCB as well as on
the terminal block: Actual and Setpoint monitors,
Integrator Time Constant Capacitor, and Supply
Voltage.
We recommend using a minimum of 22 AWG wire
to the thermoelectric.
To Install the HTC on the HTCEVALPCB
Evaluation Board with HTC Heatsink
1. Feed the HTC pins through the large opening in
the HTCEVALPCB board so that the HTC pins
are on the top side of the evaluation board and
the mounting tabs are against the back side of
the board.
2. Line up the heatsink holes behind the HTC and
insert the screws through the evaluation board
and HTC unit into the tapped heatsink holes.
3. Line up the HTC pins on the solder pads on the
evaluation board and tighten the screws.
4. Solder the HTC pins to the solder pads.
NOTE: Do not exceed 700°F soldering
temperature for more than 5 seconds on any pin.
5. If you are using a PCB that is not 0.062” thick,
the HTC pins need to be bent. Clamp the pins
between the HTC housing and the bend to avoid
damage to the HTC.
Configuration Switch - SW1
The Configuration Switch selects the OUTPUT
MODE, LIMIT RANGE, SETPOINT INPUT, and
SENSOR BIAS CURRENT. Before applying
voltage to the HTCEVALPCB, check the switch
settings for proper configuration.
