PR3331, DIN rail temperature converter, loop-powered - isolated
* Excellent accuracy, better than 0.05% of span
* Slimline housing of 6 mm
* Excellent EMC performance and 50/60 Hz noise suppression
* Selectable < 30 ms / 300 ms response time
* Pre-calibrated temperature ranges selectable via DIP-switches
Application
* The 3331 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated passive analog current output signal.
* High 2 port isolation provides surge suppresion and protects the control system from transients and noise.
* The 3331 can be mounted in the safe area or in Zone 2 / Division 2 areas.
* Approved for marine applications.
Technical characteristics
* Flexibly loop powered by 5.5...35 VDC via connectors.
* < 30 ms fast response time with simultaneus sensor error detection when selected.
* Selectable 300 ms response time when signal dampening is needed.
* Selectable internal/external CJC.
* Excellent conversion accuracy in all available ranges, better than 0.05% of span.
* Meeting the NAMUR NE21 recommendations, the 3331 provides top measurement performance in harsh EMC environments.
* The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
* All terminals are protected against overvoltage and polarity error.
* High galvanic isolation of 2.5 kVAC.
* Excellent signal/noise ratio of > 60 dB.
Mounting / installation / programming
* Selectable DIP-settings for easy configuration of more than 1000 factory calibrated measurement ranges.
* The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.
