This is a nice manifold but, with just a single photo, precious little information about it in the description and no additional drawings or instructions available, you might have a lot of questions. Hopefully I can answer some of them here (wish I could include photos).
Here's what you need to know:
The mainfold is a single piece of aluminum which measures 53mm (2.1') wide x 71mm (2.8') long x 21mm (0.85') high (without solenoids) or fittings installed. The weight is approximately 158 grams (5.57 oz.). The bottom of the unit is machined to fit onto a DIN rail. There are three threaded (1/8' NPT) holes in each of the short sides. They are labeled 5R, 1P and 3R on the top. In addition to the numerous holes drilled into the manifold to accommodate the solenoids, there are four additional holes (approx. 3/16'), 2 at each end. 2 of these 4 holes are tapped to M5, presumably for mounting or locking the unit onto a DIN rail with an M5 setscrew. The package includes 3 small (1/8' NPT) plugs and no instructions.
If you are trying to determine if you will have space for this on your robot, consider that the dual solenoids increase the total height to approximately 65mm (2.56') with fittings and the pneumatic tubing for your cylinders will have to come in the top as well. Also, the width will increase to a minimum of 102mm (4') with minimal space for the wires. In the long dimension, you will have to add a fitting for the air inlet (1P) and of course associated tubing.
While there are no instructions, if you are familiar with pneumatics it is pretty easy to figure out where everything goes, and it's nearly imposible to install the solenoids incorrectly, as long as you don't forget the gaskets. I hope this has been helpful.
