I am currently working on my first large project, which involves switching a small solenoid (sprinkler valve) via a relay for ~1-2 second(s) every 1-2 minute(s) for 6 hours / day (< 1,000 / day).
I have been able to find some information about switching higher voltage + amperage inductive loads, but was looking for a bit of guidance re: lower voltage + amperage.
Solenoid is a 24VAC Orbit 57281
AC power supply reduces main voltage to provide 25.5 VAC / 650mA
Relay module is a multi-channel opto-isolated module; 5VDC power supply (https://www.amazon.com/gp/product/B01HEQF5HU/ref=ppx_yo_dt_b_asin_title_o01_s00)
The relay module is using a pretty standard Songle SRD-05VDC-SL-C, which is rated for 10A @ 250VAC
I have read from various sources (including this forum) that if the relay is sufficiently oversized, potential inductive loads don’t present a significant issue. I come from a SWE background and am still working on my EE (quite a ways to go!), so would really appreciate any thoughts. Thanks!
