RTD Measurement for PCI

The PCI390 features six 2-, 3-, or 4-wire high-accuracy RTD measurement channels. Each channel has programmable alarm limits on which an interrupt can be issued.
The local DSP (TMS320C203) performs linearization, auto-calibration and alarm-limit checking. Sensor-data is available in °C, °F, K and Ohms. All inputs are optically isolated from the system.
