NEW! Siemens 3RQ2000-1BW00 SIRIUS 24-240V AC/DC Coupling Relay
This relay carries the Allen-Bradley brand, which many electric the job.
You will find that Uxcell is the brand on this relay, and that may matter for your setup.
What stands out about this relay is the Brown Boveri Electric Inc. name on it, and I like that.
