| Question | How should I wire your RTD0100 series of RTDs to the FC-R1 RTD signal conditioner? |
| Answer | The RTD0100 series is our four wire RTDs. Two each of the wires are connected to each side of the RTD. PIN # WIRE COLOR 1 BROWN 2 WHITE 3 BLUE 4 BLACK So for our RTDs, BROWN and WHITE are connected to the same point on the RTD and BLUE and BLACK are connected to the other point. The RTD input of the FC-R1 has three connections: + (plus), - (minus), and COM. In order to wire our four wire RTD to the FC-R1 input, one of the wires should remain disconnected on the RTD0100 cable. The other wire that connects to the unused wire on the RTD is the wire that should be connected to the + (plus) terminal of the FC-R1. As an example, if you don’t use the BROWN wire in the RTD0100, then the WHITE wire should be connected to the + (plus) terminal. The other two wires, BLUE and BLACK in this example, should be connected to the – (minus) and COM terminal. It does not matter which color is connected to which terminal for these two wires. To restate the example, don’t connect the BROWN wire of the RTD0100 to anything. Connect the WHITE wire to the + (plus) terminal of the FC-R1, connect the BLUE wire to the – (minus) terminal, and the BLACK to the COM. This will properly connect the RTD0100 to the FC-R1. Other combinations can be wired and be correct, but this is an illustration of one combination. If you need to extend the wire for the RTD run, we recommend Belden 8403 or equivalent. |
