Integrated control for ATEX compliant module
Burkert's Type 8650 AirLine-EX valve system offers the control engineer the opportunities of significantly reduced design, installation, validation and operating costs in ATEX applications.
The 8650 valve design integrates directly into the Siemens ET200iSP Profibus DPV1 distributed I/O system, combining digital pneumatic output modules with integrated electronic analogue and digital I/O. The resulting system uses a single fieldbus node and is suitable for installation in Zone 1/21, with electronic I/O and actuation/air connection possibilities into Zone 0/20. This system concept also allows for redundancy of both the bus coupler and power supply module. The system allows up to 48 Bürkert EExia solenoid valves to be combined with the Siemens ET200iSP EExia/ib I/O modules.
The 8650 system offers the way forward for control system design in hazardous areas. Its cost-effective integration of pneumatic and electronic control technologies and advanced Profibus DPV1 communications relieves the control engineer of the task of installing the many special expensive electrical junctions and terminals required by conventional field-wired systems in ATEX areas.
