RTD Measurement for CompactPCI

The CPCI390 has a 3U form factor and 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. Sensordata is available in �C, �F, K and Ohm. All inputs are optically isolated from the system.

This CompactPCI card is availabe in a 3U and a 6U form factor.
