Thermocouple inputs offer a choice of two or four terminals that allow direct connection of thermocouples. They allow for temperature selection, with a linear response across the full temperature range. The 2-channel analogue input device allows for direct connection of two thermocouples and the 4-channel analogue input device allows for direct connection of four thermocouples. The Bus Terminal’s circuitry can operate thermocouple sensors using the 2-wire technique. The temperature range is selectable and the response is linear. Compensation for the cold junction is made through an internal temperature measurement at the terminals. In addition to temperature, these inputs can also be used for mV measurement.
