In Action

The thermocouple Soft-Device provides for direct connection to any mix of eight standard thermocouple types.  There are no external amplifiers or interface circuits required.  What could be simpler?  Of course, you can use an external amplifier to convert the thermocouple signal to a standard format such as 4--20mA for long signal runs, but hooking the thermocouple directly to Soft-I/O is simpler and less expensive.  You need to be cognizant of the fact that connecting a thermocouple to the Soft-I/O connector will result in one or two additional thermocouple junctions, so you will need cold junction compensation.  But Soft-I/O provides cold junction compensation at the Soft-I/O connector.  You simply need to insure that the junctions are iso-thermal with the Soft-I/O connector.  How do you do that?  Merely connect the thermocouple directly to the Soft-I/O connector.  It's that simple. 

Technical Specifications

Each Thermocouple Soft-Device will provide one continuously variable--analog input to Soft-I/O.  You select the thermocouple type.  Soft-I/O supports type K, J, B, N, E, R, S and T thermocouples.  You select the type of cold junction compensation.  The simplest is the Soft-I/O internal cold junction compensation where Soft-I/O assumes that the thermocouple wires are iso-thermal with respect to the Soft-I/O connector.  Soft-I/O will compensate for the temperature of the connector.  Soft-I/O produces a compensated temperature measurement in your choice of engineering units, degrees C, F or Kelvin.  You can then use your configured thermocouples for temperature measurement, temperature control or data logging.  What could be simpler or less expensive?
