Electronic timer relay


SteveReed1

Hi, 

we have a customer with a rubber press machine, control voltage is 24VDC. We have a proximity sensor that through a relay switches ON a vacuum valve. Whilst the PS is triggered - up to 20mins, the vacuum valve is open. This valve appears to be over-heating. The machine only requires the vacuum for 20 seconds, so we need a 24vdc timer relay to shut off the supply to the valve after 20seconds. Can you suggest a suitable timer relay, remembering that the supply is ON for 20mins, then off for 5 mins and then back on for 20mins and so on....

Thank you
