RSA: Rail System Assemblies

Click image to enlarge
The 1-1/2”x3” Aluminum extrusion profiles include 3/8” NPSF ports at each end, one for air supply and the other for a plug or a pressure gauge. Rails are drilled to mount modules on center-to-center distances to your specifications. The minimum recommended spacing is 1-1/2 in. (38.1 mm) but is also dependent on suction cup diameter. RS18 modules will be mounted to the rail and tested by EDCO USA. Pilot port fittings, zone tubing, and 3-way air solenoid pilot valves must be installed by the system integrator because of the many possible configurations.

Pump modules, pipe plugs, vacuum cups, and supply line fittings are sold separately. When  rail system assembly is ordered with the correct number of rail system pump modules, we will ship your rail system assembled with the pump modules in place. All vacuum cups, pipe plugs, and supply line fittings will be included with your shipment and must be assembled by you.

How to Order

Please be sure to include a zero when the dimension is less than one and round all dimensions to two decimal places as shown in the examples below.

Please double check that your configuration will not exceed the maximum 48" length of the rail. Details for figuring out the total rail length can be found below. The equation for figuring out total rail lengh is listed below.



Profile Length

Minimum recommended center-to-center spacing is 1.5 inches. It's important to know the diameter of the cup you'll be using as this will also determine the minimum spacing required. The minimum recommended end spacing is 0.9 inches. Machined rails have a maximum length of 48".

Equation:

((Number of Modules on one side - 1) x Module Spacing) + (End Spacing x 2) = Profile Length
 

Examples:

RSA20-1.5-0.9-S: 20 Modules, 1.5 Module Spacing, 0.9 End Spacing, Single Sided: ((20-1) x 1.5) + (0.9 x 2) = 30.3
RSA14-1.75-1.2-D: 14 Modules, 1.75 Module Spacing, 1.2 End Spacing, Double Sided: ((7-1) x 1.75) + (1.2 x 2) = 12.9
