1.5 Technical Data
Input
Selectable filters for suppres-
sing line frequencies 50/60 Hz (additional 10 Hz for special
applications)
Resistance thermometer
Sensor type Pt10, Pt50, Pt100, Pt200, Pt1000 (IEC 751,
DIN 43760, JIS C 1604-97, BS 1904)
Pt10, Pt50, Pt100 (JIS C 1604-81):
Ni50, Ni100, Ni120, Ni1000 (DIN 43760)
Measuring type Standard (logic channel 1),
Averaging connection or differentiating
connection (of 2 channels)
Standard 1 resistance thermometer in two, three or
four-wire circuit
Averaging connection Averaging connection between two re-
sistance thermometers in two-wire circuit,
parameterizable equivalent value behavior
(e. g. the value of the other channel is output
when the channel is defective)
Differentiating connection Differentiating connection between two resi-
stance thermometers in two-wire circuit, diffe-
rence is parameterizable (e.g. channel 2 –
channel 1).
Series or parallel
circuit
Series or parallel circuiting of several
resistance thermometers in two-wire circuit,
e.g. to adapt other transmitter types, is
implemented as an additional function. This
gives a scaling factor.
Adjustment at
Two-wire circuit Line resistance parameterizable
≤
5 % of the
measuring range
Three-wire circuit No adjustment necessary. The line
resistances must be equal between the
respective sensor connection and the
appropriate connection on the transmitter.
Four-wire circuit No adjustment necessary.
Sensor current
≤
0.55 mA
