GEYA Delay Off Single Function Time Relay 2 Outputs 16A Electronic Power Off Timer Delay Relay(GRT8-B2,AC/DC12V-240V)

Relay works as described except for the input voltage.It requires a neutral on one leg of the input or it will fry the timing circuit.The description says it will use up to 240vac but should read 230v for the European voltage levels with a neutral.

This is a useful little smart relay.But, one gotcha that I didn't catch - the relay fires a cycle on power-up. I thought it was only on assertion of the S signal, but it does happen at power up also.And one other minor complaint - there's a high-pitched tone from this when operating off of 12V. Sounds like a switching power supply.

worked great , easy to install .

Great little relay. Fyi when the power is cycled to the relay (not talking trigger power) it will activate. I used mine for strobes so its fine. But if used in a more sensitive situation just be mindful.

NOT a Delay-OFF timer. This does NOT have a true Delay-OFF timer function. It is an Interval timer as the contacts switch state immediately after power is applied, starting the initial time interval WITHOUT any signal provided. It will then switch contacts back to original state after the initial automatic interval times out. This can be very DANGEROUS if trying to control equipment. Subsequent application of the Signal line will cause contacts to change state. Thereafter when Signal is removed, the time interval restarts and the contacts will return to original state at the end of the time interval.NOTE: Model GRT6-Mxx DOES have a true Delay-Off function.
