Emerson enables reduced cost and complexitywith zoned safety valve island
Emerson has introduced the ability to integrate multiple safety zones within a single ASCO Numatics™ Series 503 valve island. This enables the creation of up to three independent electro-pneumatic safety zones, while also allowing independent non-safe sections to co-exist within one valve island assembly. Alternative solutions enable the isolation of one zone only per island. The zoned safety approach helps the design engineer satisfy the Machinery Directive 2006/42/EC and comply with ISO 13849-1 while eliminating the components and complexity commonly found in existing safety circuits.
“With this functionality, the original equipment manufacturer (OEM) and end user can easily and cost-effectively configure up to three safety circuits in a machine using a single ASCO Numatics Series 503 valve island with G3 fieldbus electronics,” said Scott Weickel, Vice President of Engineering for Machine Automation applications at Emerson. “Our simple, user-friendly zoned safety
