Control- and feedback head for integrated mounting on Robolux valves Type 2036

Feedback Type 8685 and control head Type 8686 are optimized for integrated mounting on pneumatically operated actuators Type 2036 Robolux. The adjustment to the individual actuator size is done through DIP-switches. As compact units the devices contain the complete automation functionality of both individually operated actuator pistons. Depending on the conﬁguration the electrical and visual position feedback is done by non-contact switches and high-power LEDs. Integrated pilot valves control the actuator pistons and AS-interface communication is available. Using appropriate barriers both types feature intrinsically safety acc. to ATEX. In this way a complete concept for decentralized automation is feasible. The compact body is especially destinguished by its hygienic design, materials beeing chemically resistant against cleaning media and a proven IP protection. In addition the Control Head Type 8686 features an integrated compressed air ﬁlter to protect the pilot valve function against particles through the compressed air supply.
