Thermocouple Input Card
- 4 thermocouple input channels.
- DIP switch addressable; stack up to 32 modules on the same serial port for 128 inputs.
- Accepts types J, K, T, E (ungrounded) thermocouples.
- Each channel individually selectable to read temperature in Fahrenheit or Celsius.
- Temperature conversions use high-order polynomial equations eliminating look-up table interpolation errors.
- Built-in cold junction reference, no external ice-point necessary.
- Thermocouple inputs protected to ±40 volts.
- Software calibrated; no trim-pots to adjust.
- All user configuration and calibration data stored in non-volatile memory.
- Wide power supply range (8 to 30 VDC).
- Optional enclosure also available.

Connects to a PC or Laptop using our USB Cable or to any other host which incorporates an RS-232 serial port. Stack multiple cards together on the same port. Attach up to four separate thermocouples of various types and use the host to read the temperatures of each. Simple command strings sent from the host will initiate a conversion on an input channel which in turn will, read the thermocouple voltage in µV, convert it to temperature, then add the cold junction reference temperature. The results returned to the host will be equal to the absolute temperature of the thermocouple tip and can be listed in degrees Celsius or Fahrenheit. This module is ideal for wide range temperature measurement in harsh industrial environments using a PC or laptop for data collection.
