Note
This unit requires 12v dc to power it at all times. (10-14v dc).
If the input is not removed when the timing has finished in both
momentary trigger modes, then the led will remain illuminated red

Contact ratings
The relay is DPCO rated 1Amp @ 12v dc. It must not be used to
switch mains voltages.

Boxed Version. If you have the boxed version of the S351, the decal
(included) has a clear window 10mm x 46mm. The area under the
decal is 12mm wide to take standard labelling machine tape. The
window is free from adhesive, nevertheless, it is wise to maintain
cleanliness and avoid fingerprints on the inside of the window. If a
labelling machine is not available a paper label can be used. For a
small extra charge these products can be factory labelled to your
requirements (subject to a character limit).
