The PCI temperature measurement board APCI-3200 has 16/8/4 channels for thermocouples or 8 inputs for resistance temperature detectors (RTD). Each channel can be configured either to thermocouples, RTD or as an analog voltage input channel. Furthermore, the board has 8 independent current sources for resistance temperature detectors (RTD) and one current source for the cold junction compensation.
