<ul>  
<li> * Excellent accuracy, better than 0.05% of span</li>  
<li> * Slimline housing of 6 mm</li>  
<li> * Excellent EMC performance and 50/60 Hz noise suppression</li>  
<li> * Selectable < 30 ms / 300 ms response time</li>  
<li> * Pre-calibrated temperature ranges selectable via DIP-switches</li></ul>  <br /><br />
<h3>Application</h3> 
<ul>  
<li> * The 3331 temperature converter measures a standard Pt100, TC J and K temperature sensor, and provides an isolated passive analog current output signal.</li>  
<li> * High 2 port isolation provides surge suppresion and protects the control system from transients and noise.</li>  
<li> * The 3331 can be mounted in the safe area or in Zone 2 / Division 2 areas.</li>  
<li> * Approved for marine applications.</li></ul> <br /><br />
<h3>Technical characteristics</h3> 
<ul>  
<li> * Flexibly loop powered by 5.5...35 VDC via connectors.</li>  
<li> * < 30 ms fast response time with simultaneus sensor error detection when selected.</li>  
<li> * Selectable 300 ms response time when signal dampening is needed.</li>  
<li> * Selectable internal/external CJC.</li>  
<li> * Excellent conversion accuracy in all available ranges, better than 0.05% of span.</li>  
<li> * Meeting the NAMUR NE21 recommendations, the 3331 provides top measurement performance in harsh EMC environments.</li>  
<li> * The device meets the NAMUR NE43 standard defining out of range and sensor error output values.</li>  
<li> * All terminals are protected against overvoltage and polarity error.</li>  
<li> * High galvanic isolation of 2.5 kVAC.</li>  
<li> * Excellent signal/noise ratio of > 60 dB.</li></ul> <br /><br />
<h3>Mounting / installation / programming</h3> 
<ul>  
<li> * Selectable DIP-settings for easy configuration of more than 1000 factory calibrated measurement ranges.</li>  
<li> * The narrow 6 mm housing allows up to 165 units to be mounted per meter of DIN rail, without any air gap between units.</li>  
<li> * Wide ambient temperature range of: -25...+70°C</li></ul>
