Resistive 1000 Ω Temperature Sensor; Table 5 Analog Input Wiring - Mircom OpenBAS-LC-NX12R Installation Manual

Table 4 Analog Input Wiring (Continued)
Type of field device Power source
3 wire transducer with 4-
20 mA or 0-20 mA
output
Connect an external 250
Ω ½ Watt 1% load
resistor in parallel
between the universal
input terminal and 0V to
provide a return path for
the transducer signal
current.
J or K Thermocouples
When using J or K
thermocouples, install a
x200 low offset amplifier.
4.5.3 Resistive 1000 Ω Temperature Sensor
For resistive temperature sensors, the jumper J1 must be shorted. See section 4.4 on
page 22. For all other devices, the jumper must be open.
