Parker has developed a fully integrated fieldbus manifold system for the control of pneumatic actuators in Zone 1 and Zone 2 process industry environments. The EExPress Bus Manifold is a stackable valve system that fully integrates 5/2 solenoid valves, control electronics and input sensors, and uses the Profibus DP fieldbus communications protocol. One bus address can operate up to 32 individual 5/2 modular solenoid valves, or a combination of valves and actuator position sensors.
The concept consists of an integrated solution which permits to install the manifold close to the pneumatic actuators – without the need for expensive explosion-proof pressurised cabinets. The EEx p [ia] m IIC T5 protection is reached by putting the complete block under 50 mbar safety pres-sure. Diagnostics is another safety factor thanks to a wide diagnostics capability – from the uninterrupted power supply (UPS) to the solenoid valves and sensors. The sensors are directly connected to the manifold which is a complete integrated control system.
