FlexTop 2211 Universal Transmitter 4...20 mA transmitter RTD, T/C, mV and R inputs Isolation voltage 3.75 kV ac Configuration via FlexProgrammer Accuracy better than 0.1C (Pt100) Configurable linearisation, damping and status indication Local, remote or fixed compensation forcold junctio (CJC) Ex approvals: Ex ia IIC T5/T6, ATEX II 1G Ex nA II T5, ATEX II 3G Description FlexTop 2211 is a 4...20 mA loop-powered, configurable universal FlexTop 2211 is embedded in silicone which makes it resistant to humid transmitter with galvanic isolation between input and output. The input environments. can be configured for RTD or T/C sensors, resistance, current or The configuration can be established from the dedicated FlexProgrammer voltage signals. configuring tool connected to a PC. Either 2-, 3- or 4-wire connection can be selected for the resistance FlexTop 2211 has a 6 mm center hole for fast sensor replacement and input. The built-in temperature sensor or a remote Pt100 sensor can spring loaded mounting screws which ensure a safe fastening even in be used to compensate forcold junctio (CJC) if thermocouples are vibrating environments. connected. www.baumer.com/process Data sheet 2211-1 Design and specifications subject to change without notice Page 1 Technical Data Input EMC data Digital accuracy See Measuring ranges Immunity EN 61326 CJC-compensation 1 Local < 0.5C Emission EN 61326 Remote < 0.2C NAMUR NE 21 RTD measuring current 0.2 mA, continuously Approval Ex ia IIC T5/T6, ATEX II 1G Cable resistance Supply range 6.5...30 V dc 2-wire Max. 30 Ohm/wire 1 Internal inductivity L < 15 H i 3-/4-wire T > 600C: Max. 10 Ohm/wire Internal capacity C < 5 nF 3-/4-wire T < 600C: Max. 30 Ohm/wire i Protection +/- 35 V Barrier data U < 30 V I < 0.1 A P < 0.75 W dc dc Suppression 50 and 60 Hz Temperature class T1...T5: -40 < T < 85C amb Resolution 16 bit T6: -40 < T < 50C amb Repeatability < 0.05C Mechanical data Dimensions 44 x 26.3 mm Output Signal span 4...20 mA, 2-wire 1 Protection class Housing: IP 55 20...4 mA, 2-wire 1 Terminals: IP 10 Characteristic Linear or customised with Other data max. 30 points 1 Isolation 3.75 kV ac Accuracy < 0.1% of signal span Temperature drift Typ. 0.003% per C Supply range 6.5...35 Vdc Max. 0.01% per C Ripple immunity 3 V rms Power-on time 1.8...3.9 sec.
