Relays In Series. Safety rated contactors have built in monitoring and built in dual contacts in series The above photo is of a pair of nonsafety rated contactors that have been configured to comply as a safety rated power contactor From the description of a safety rated contactor from Rockwell / Allen Bradley Bulletin 100SC/104SC safety contactors provide.
We want to use two zener diodes in series reverse biased across the relay coil so that we can build one board and utilize either PLC output style without modifications The relay coil common voltage is jumper selectable The relay draws 51mA when energized We are having trouble deciding what power rating the zeners need to be.

ANSWER • We cannot recommend the use of relays in series connection on the input side because it may cause (transitionally) an undervoltage or an overvoltage due to differences in coil resistance • When you use multiple relays connect them in parallel basically to make sure that the rated voltage is applied to the coils.
