UNIVERSAL I/O INTERFACE
preliminary
Rev A1, Page 1/55
FEATURES
• Two channels, each configurable as input or output
• Low-side and high-side switches with up to 500 mA per channel,
current limitation, current measurement, status messages,
cable break detection, freewheeling and reverse polarity
protection, paralleling of both channels possible
• Output of ±10 V or 0/4...20 mA with 14 bit resolution
• Measurement of ±10 V, ±1 V, ±100 mV, ±10 mV, ±20 mA,
4...20 mA with 14 bit resolution
• Input for Pt100, Pt1000 temperature sensors
• Multifunctional 32 bit counter
• Digital output with pulse-width modulation option
• Internal temperature measurement with 1 K resolution
• SPI interface
• Calibration and configuration by external EEPROM via serial
interface
• Error message with hysteresis at overtemperature, overload
and undervoltage
• Shutdown of the outputs in case of error
• Inputs/outputs protected against ESD
APPLICATIONS
• PLC control systems
• Data acquisition
• Sensor interfaces
