You shouldn't be worrying about "impedance" on a DC relay. Just measure the resistance with a Voltmeter/Ohmmeter. If you need to know the current draw, it will be 24/resistance The impedance of an AC relay changes as the armature moves from the "off

Could anyone send me equations to calculate controlled impedance of traces on circuit boards. I am most interested in the buried traces in multi layer boards. Thanks, David - piengr@verinet.com

For the last couple of years, the main concerns regarding the electrical performance of blank PCB boards were impedance and ohmic resistance. Just recently, the need to reduce insertion loss came up in discussions with blank board customers (...) The paper describes the test vehicle and the testing methodology and discusses in detail the electrical performance characteristics. The influence of the independent variables on the performance characteristics is presented. Finally the thermal reliability of the boards built applying different copper foils and oxide replacements was investigated.
