Max. permissible residual ripple 10 % at 24 V / maximum 300 Ω Load

Power supply input protected against reverse polarity

Power supply eect ± 0.025 % / V

Electromagnetic compatibility

(EMC)

2004/108/EC, DIN EN 61326 emission (Group 1, Class B) and immunity

(industrial application)

, and also per NAMUR NE21

Temperature units congurable °C, °F, K

Info data TAG No., descriptor and message can be stored in transmitter

Conguration and calibration data

permanently stored in EEPROM

Electrical connection Angular DIN connector Form A, M12 x 1 circular connector, 4-pin

Explosion protection (option)

Intrinsically safe to Ex-i (ATEX) gas/dust, per Directive 94/9/EC

Marking: II 1G Ex ia IIC T* or II 2D Ex iaD 21 T*

Safety-related maximum values for the current loop (+ and - connections):

Ui = DC 30 V C

= 6.2 nF I

= 120 mA L

= 110 µH Pi = 800 mW

Readings in % refer to the measuring span

For a correct determination of the overall measuring error, both sensor and transmitter measuring deviations have to

be considered.

For detailed specications for Pt100 sensors, see Technical Information IN 00.17 at www.wika.com.

The temperature transmitter should therefore be protected from temperatures over 85 °C

For measuring spans smaller than 50 K additional 0.1 K

± 0.2 % for measuring ranges with a lower limit less than 0 °C

Use RTDs with shielded cable, and ground the shield on at least one end of the lead, if the cables are longer than 30 m or leave the

building.
