I am developing a prototype 12V system comprising a solenoid activated by a PIR sensor. I am looking for a timer device so that the power to the solenoid cuts 1 or 2 seconds after activation.
This is as a safety back-up. The PIR sensor should cut out after a minute but it's a bit long and sometimes the power to the solenoid is getting stuck on.
Would this timer be suitable :RS Stock No.: 178-5026 (https://uk.rs-online.com/web/p/timer-relays/1785026?cm_mmc=UK-PLA-DS3A-_-google-_-PLA_UK_EN_Relays_Whoop-_-Timer+Relays_Whoop-_-1785026&matchtype=&pla-419938658867&gclid=EAIaIQobChMI5PCB_rSE9wIVyOvtCh3mPQkXEAQYASABEgLCN_D_BwE&gclsrc=aw.ds be suitable) .
