Traditionally, safety circuits were independent of the network. This was deemed the fastest, least complex and most reliable way to implement safe function. Isolated circuits working alongside the ...

The Machine Primary Control Elements (MPCE) 1 and 2 are typically a relay with force guided contacts. When a safety interlock, light curtain, or e-stop switch opens a circuit, the MPCE NO contacts ...

Faced with ever-increasing cost pressures and demands for improved performance, machine builders are actively seeking new automation solutions with improved cost/performance ratios. In response to ...

Disconnect switches play an important role in ensuring the safety and efficiency of industrial machinery. As key components in electrical systems, they provide a reliable means for safety isolating ...

Functional safety accounts for time — to build on existing safety structure (category) approaches. As we explored last month in this article series, accounting for time requires more work from safety ...

A single PSR-TRISAFE safety controller can monitor an entire safety circuit from emergency stops to safety doors in a machine or plant. The 67.5-mm controller monitors up to 20 safety input signals ...

A single global machine safety standard has been in the works for a long time and will now be a little longer. The merger of safety standards ISO 13849 and IEC 62061 into one standard, IEC/ISO 17305, ...
