Functional highlights
- Temperature converter which measures a standard 2-, 3- or 4-wire Pt100 temperature sensor, and provides a passive analog current output signal.
- All terminals are over-voltage protected, polarity protected and short-circuit protected.
- The device can be mounted in Safe area or in Zone 2 / Division 2 areas and is approved for marine applications.
Technical highlights
- Flexibly loop-powered by 3.3...35 VDC via connectors.
- Excellent conversion accuracy in all available ranges, better than 0.1% of span.
- < 30 ms fast response time with simultaneous sensor error detection when selected.
- Selectable 300 ms response time when signal dampening is needed.
- Meeting the NAMUR NE21 recommendations, this device ensures top measurement performance in harsh EMC environments.
- The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
- Excellent signal / noise ratio > 60 dB.
- Wide ambient temperature range: -25...+70°C.
Programming
- Easy configuration via DIP switches.
- Selectable DIP settings for easy configuration of more than 1000 factory calibrated measurement ranges.
Mounting / installation
- The narrow 6.1 mm housing allows up to 163 units per meter.
- Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 70°C ambient temperature.
