6.1.2 Technical Information for WTR-230AC
Input Resistance Thermometer
Description
PT100 2-wire connection
according to DIN EN
60751
Sensor line resistance: max. 30 [Ω] per line with a three-wire circuit
Measured current: PT100 ca. 1 [mA]
Line balancing:
For a two-wire circuit, a line balancing can be performed through a correction of the actual value (see
chapter 7.3 Configuration (ConF)).
