Coil H16-12D-29W-DE-DB - Danfoss ICS robust coils R13, R16 and H16 with the product code DB use two-way transient diodes (TVS) integrated in the coil. TVS diodes have the task of protecting the system against unwanted voltage spikes induced from the coil. These are two-way diodes and are therefore not polarity dependent. This means that no account must be taken of which pins must be used.
