Bürkert control system
Bürkert are offering a modular pneumatic/electronic control and communication system that reduces wiring in ATEX applications to a single Profibus cable. The company’s 8650 system 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 result is a device that uses a single fieldbus node, which is suitable for installation in zone 1/21, with electronic I/O and actuation/air connection possibilities in zone 1/20. This system concept also allows for redundancy of both the bus coupler and power supply module.
Bürkert say their 8650 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 engineer of the task of installing the many special and expensive electrical junctions and terminations required by conventional field-wired systems in ATEX applications.
