Electrical connection with plug for extendable valves (cable plug Type 1057 for individual wiring)

Cable plug Type 1057 can be selected with plug configuration at top (see “Connection variants for port connection 2 (working

ports)” on page 9). The main prerequisite is that the base module is selected for width/station 18 mm. Neutral and protective

conductors are looped through and connected centrally once. When connecting the valves, only the control line to each valve must

be installed. The neutral and protective conductors are integrated in the cable plug. The major advantage of this system is that a

valve can be removed from the block without difficulty.

Note:

The cable plug Type 1057 is available only in conjunction with the individual base module width/station 18 mm.
