6. P July 2013 E 8 MicroLogix 1200 RTD Resistance Input Module RTD Wiring Considerations Since the operating principle of the RTD module is based on the measurement of resistance take special care when selecting your input cable For 2 wire or 3 wire configurations select a cable that has a consistent impedance throughout its entire length Configuration Recommended Cable 2 wire Belden 9501 or equivalent 3 wire less than 30 48 m 100ft Belden 9533 or equivalent 3 wire greater than 30 48 m 100 ft or high humidity conditions Belden 83503 or equivalent IMPORTANT The RTD module requires three wires to compensate for lead resistance error We recommend that you do not use 2 wire RTDs if long cable runs are required as it reduces the accuracy of the system However if a two wire configuration is required reduce the effect of the lead wire resistance by using a lower gauge wire for the cable for example use AWG 16 instead of AWG 24 The module s terminal block accepts two AWG 14 gauge wires When using a 3 wire configuration the module compensates for resistance error due to lead wire length For example in a 3 wire configuration the module reads the resistance due to the length of one of the wires and assumes that the resistance of the other wire is equal If the resistances of the individual lead wires are much different an error may exist The closer the resistance values are to each ot
