WIRING
•
Use 18 - 24 AWG shielded wiring for all connections. Do not locate the device wires in the same conduit with wiring used to supply inductive
loads such as motors. Make all connections in accordance with national and local codes.
•
Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wiring diagrams below. All
connections should be made using either butt-splices or soldering. The use of wire nuts is not recommended.
•
All thermistors and most RTD's are a 2 wire hook up and are not polarity sensitive. See Figure 6.
•
For RTD’s that are 3 wire connection see Figure 7.

TYPICAL WIRE RESISTANCE VALUES
When using low resistance sensors, long wire runs can add
significant error to the readings. Use the following chart to
determine errors due to wire resistance or consider using a
1000 ohm sensor or a transmitter for better accuracy. Locate
the type of wire being used. Multiply the total length of the
wire (distance from the controller to the sensor and back)
by the number found in the chart below for total resistance.
