Maximizing Flexibility in Distributed I/O and Valve Systems

Manufacturers of automation components have long made pneumatic valve terminals with IP65 and IP67 ratings that can be mounted anywhere on a machine. This is particularly useful for connecting valves as close to pneumatic actuators as possible. Doing so shortens the length of tubing, reduces the occurrence and severity of leaks, and increases actuator performance by shortening cycle times. Decentralized valve terminals communicate with the machine controller or PLC via an industrial Ethernet network. In addition to valves, terminals are configured with input and output modules to allow for easy connection of sensors, switches, and other field-level devices to the industrial network.
