Q: I want to run a 12 volt motor for 30 seconds each time a float switch is actuated.. will this do that

You will have to have a DC “trigger” to activate the fan. In ours we have a 12 volt DC motion detector as the trigger. When the motion detector senses motion it sends a 12 volt signal to the relay on the trigger side. That initiated the timer. Ours is set in the P2 mode which makes the timer reset each time it receives a signal. In other words if we set it for 900 second, which is 15 minutes, and the motion detector sends another signal to the timer at the 400 (or any other time) second mark, as it counts down, it will reset to 900 seconds each time. You will need DC voltage on the float switch to make it work.

Q: Can this be setup to leave the relay on until the contact input is released and then wait 20 seconds before releasing the relay?

Yes. Program P7 will energize the relay immediately after a high or low trigger, then delay a set interval after the signal stops before de-energizing.

Q: What are the dimensions of this board please? Do you have any recommended enclosures?

Outside dimensions are 1.513"(38.42mm) wide and 3.143"(79.83mm) long. Thickness is .783"(19.9mm). Hole spacing is 1.25"(31.75mm) by 2.9"(73.67mm). You need space at both ends of the board for the wires, and if you are going to use the micro USB connector, you need space at the top edge also. The board has components mounted to the bottom, so when mounting it into a box, you need to use standoffs, Parts on bottom stick out 1/8"(3mm). I would recommend a plastic box with plastic standoffs. The board comes with plastic feet that clip into the mounting holes, but they are not useful for permanent mounting. The enclosure is determined by the voltage used, and the type of environment. (low voltage or AC mains, indoor or outdoor, wet or dry) I used mine to drive a 120V AC motor, indoor. So I used a plastic Bud Box, and a solid state relay to switch the current. (I needed to switch about 15 amps) I had to make holes in the box to vent the heat from the solid state relay heat sink and low voltage power supply. If outdoors, it would have been a sealed box, and probably made out of cast aluminum to dissipate the heat from the solid state relay. (The box itself would be the heat sink) I would recommend a Hammond or Bud enclosure. The cheap Uxcell enclosures I purchased were both crap and needed modification/repair before I could use them. And they cost just as much as the better Bud box.
