Based on the Rs value connected between pins 1 and 2, the corresponding RTD Type look up table is
utilized.
Plug connectors are available for customers that want to make up their own RTD Type standards. If no
Rs resistor is installed between pins 1 and 2, a copper wire (Rs = 0) must be wired between pins 1 and 2.
When Rs = 0 is detected, the RTD Type setting will be defaulted to the last RTD Types setting used.
This setting will display briefly at the bottom of the MFT display when the cable is attached to the RIO
module.
Option 1: RTD wiring styles for User Wired RTD Type with Manufacturer’s Plug
IMPORTANT: Pins 3 – 6 on the custom connector must all be connected for readings to take place!
2-wire RTDs
Connect pins 3 and 4 to one wire/terminal of the
RTD. Connect pins 5 and 6 to the other wire/terminal.
3-wire
RTDs
3-wire RTDs have two wires/terminals that are the same
color. Connect pin 3 to one of these wires/terminals and
connect pin 4 to the other wire/terminal of the same color.
Connect both pins 5 and 6 to the remaining, different
color wire/terminal.
4-wire
RTDs
4-wire RTDs have two wires/terminals of one color and two
of another color. Connect pins 3 and 4 to each of two
wires/terminals of the same color. Connect pins 5 and 6
to each of two wires/terminals of the other color.
