I tried to find more information with no luck, can you help?
Yes Charles, the relay we currently use on SR-RCS-202U as of Aug 2016 is model number SRA-09VDC-CL from Songle Relay.
SRA product family belongs to Songle automotive relay family, which can provide higher current switching capability while keeping a smaller size.
We have uploaded the tech specs to Scribd, you can see it here https://www.scribd.com/document/320884861/Songle-SRA-Relay-Specification
- However, please note, receiver’s current rating also depends on circuit board design, and usually is lower than that of relay’s.
Thanks for your very fast reply, and the tech specs link, it helps a lot!
