PCI390
RTD Temperature Measusrement Module
The PCI390 is a 6-channel RTD Measurement PCI card that provides high-accuracy temperature measurement data for industrial automation applications to ensure both product quality and safety.
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.
The PCI390 is also available as a M-Module, VMEbus (3U and 6U) and CompactPCI (3U and 6U) product.
