3100V106-UK 9
6 mm series of temperature and converters
3101 / 3102 / 3111 / 3112 / 3113 / 3331 / 3333 / 3337
• Converts process measurements from Pt100, TC J and K temperature sensors to
voltage or current outputs
• Multiple pre-calibrated temperature ranges are selectable via DIP-switches
• High accuracy, better than 0.05% and excellent 50/60 Hz noise suppression
• Fast signal response time < 30 ms
• 3113 and 3337 with HART 7 protocol and fast signal response time < 60 ms
• HART 7 protocol enables extended device programming for 3113 and 3337
Applications
• The temperature converters measure standard 2-, 3- or 4-wire Pt100 and/or TC J & K temperature sensors, and provides
an analog voltage or current output.
• High 3 port isolation provides surge suppression and protects the control system from transients and noise.
• The loop powered devices have high 2-port galvanic separation to eliminate ground loops.
• The devices can be mounted in the Safe area or in Zone 2 / Division 2 areas.
• Approved for marine applications.
Technical characteristics
• High conversion accuracy, better than 0.05% of span.
• A visible green LED indicates operational status and status of the input sensor.
• All terminals are protected against overvoltage and polarity error.
• Meeting the NAMUR NE21 recommendations, the system 3000 devices ensure top measurement performance in harsh
EMC environments.
• The devices meet the NAMUR NE43 standard defining out of range and sensor error output values.
• High galvanic isolation of 2.5 kVAC.
• Excellent signal/noise ratio of > 60 dB.
• Wide temperature operation range of -25...+70°C.
Programming
• Selectable DIP-mode for easy configuration of more than 1000 factory calibrated measurement ranges with HART read
only feature.
• Selectable HART-mode to enable full HART read-write capabilitytur
Mounting
• Units can be mounted side by side, horizontally and vertically, without air gap on a standard DIN rail, even at 70°C ambient
temperature.
• Units can be supplied separately (3101 / 3102 / 3331 / 3333 / 3337) or installed on PR 9400 power rail (3111 / 3112 /
3113).
• The narrow 6.1 mm housing allows up to 163 units per meter.
