Field bus system connector for control of solenoids in pneumatic systems - allows bus nodes to be connected to stretch of bus without affecting function to provide pneumatic control of solenoid valves

摘要

The connector has at least three connector parts (3, 4, 5). Each of these has a number of electric contacts (15, 16, 17, 15', 16', 17', 15'', 16'', 17''). The contacts (15, 16, 17) of any connector part (3) used for the filed bus system are connected to corresp. contacts (15', 16', 17', 15'', 16'', 17'') of all remaining parts (4, 5) via internal electric leads (15a, 16a, 17a). ADVANTAGE - Optimises system in simple manner and each part connected is unaffected by failure of others.
