F 6220 (0625)
300
3 Technical data
3.1 Low voltage input
Input voltage -100 mV...+100 mV
Linearization <
±0.1 %
Resolution 0.01 mV (with scaling 0.1 %)
Value in ELOP II -10000...+10000 (variable type INT)
3.2 Input for comparison measurement
Input for comparison Pt100 with two-wire measurement
Measurement (max. line length 6 m)
Reference temperature
Limits -40 °C...+80 °C
Resolution 0.1 °C
Value in ELOP II -400...+800 (variable type INT)
The Pt 100 input of the module F 6220 can be used as reference temperature for all channels.
As alternative it is possible to use for each channel of the module an own reference tempera-
ture.
3.3 Further data
Input resistance > 1 MΩ
Line length approx. 300 m, double screened cable,
twisted pair,
circuits load impedance max. 500
Ω
Noise voltage suppression ≥ 60 dB (common-mode 50 / 60 Hz)
Voltage endurance
< 375 V (Ex circuit -> non Ex circuit)
< 7 V (Ex circuit -> non Ex circuit)
The value in ELOP II can be scaled (0...1000) by the software function block HF-TMP-. It is
possible to select only a window of the range.
