Overall dimensions and technical information are provided solely for informative purposes and may be modified without notice Multipolar connections 1 Air distribution Solenoid valves manifold ISO 15407-2 1 | 378 Series 2700 The electrical connection is achieved by a 37 pin connector and can manage up to 32 solenoid pilots. It is also possible use a 25 sub-D pin connector and, in this case, it is possible to manage a maximum of 22 outputs. The management and distribution of the electrical signals between each valve is obtained thanks to an electrical connector which receives the signals from the previous module, uses one, two or none depending on the type, and carries forward to the next module the remaining. Bistable valves, 5/3 and 2x3/2 valves which have two solenoid pilots built in, use two signals; the first is directed to the pilot side 14 the second to the pilot side 12. Modular bases can be fitted with two type of electrical connector: the monostable version uses only one signal (connected to the pilot side 14) and carries forward the remaining, the bistable version which always uses two signals. This solution allows the modification of the manifold (replacement of monostable valves without bistable for example) without having to reset the PLC output layout. On other hand this solution limits the maximum number of valves to 16 when it is used a 37 pin connector or 11 when it is used a 25 pin connector. Intermediate supply/exhaust module uses an electrical connector directly forwarding signals to the next one without any kind of modification. This allows the use of intermediate modules in any position of the manifold. All the electrical signals that have not been used on the manifold can be used placing at the end of the manifold the end plate complete with the 25 sub-D female connector. The number of available signals depends of the connector used to the type of the left end plate and by the total signals used along the manifold: 37 pin connector nr of output = 32 – (total of used signals) 25 pin connector nr of output = 22 – (total of used signals) Following we show some examples of possible combination and the relative pin assignment.
