RTD Measurement for VMEbus

The VME390 features 24 two, three or four wire high-accuracy PT100 measurement channels. Each channel has programmable alarm limits on which an interrupt can be issued.
Quad. local DSPs (TMS320C203) perform 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.
This VMEbus board has a 6U form and is also available as 3U VMEbus board.
