Tom is right, just as I said at the end of my reply.
power supply + to + wire of probe, - of probe to + of input card, - of input card to - of power supply, not sure what card you have there, assuming it is 4-20ma input the above should work, however if the card is pt100 input then it requires the 3 wires direct from the probe (remove the 4-20 ma converter, if the probe is a four wire (2 red 2 white) then use the 2 reds & one white as the 3 wire configuration & connect both whites together as one wire.
