Safety relays like the PNOZsigma are commonly used in industrial automation and machinery where safety is critical. http://www.pilz.com They ensure that safety functions, such as emergency stops and safety gates, operate reliably to protect personnel and equipment from harm. This typically means the safety relay can monitor either one or two separate safety circuits (channels).
The safety relay monitors emergency stop (E-STOP) circuits to ensure rapid shutdown of machinery or processes when needed. It also monitors safety gates, ensuring they operate correctly to prevent access to hazardous areas during machine operation. The relay can detect short circuits across its input contacts, which is crucial for ensuring safety circuit integrity. Safety solutions provider since 2011, We offer Pilz.
These features collectively make the PNOZsigma safety relay suitable for a wide range of safety applications in industrial settings where adherence to safety standards (such as EN ISO 13849) is paramount. Plug-in spring-loaded terminals. These terminals facilitate easy and secure wiring connections.
These contacts have a time delay (adjustable between 0.04 and 300 seconds) before they switch after a signal is received. This contact is likely used for signaling purposes, such as indicating the status of the safety relay. These are standard output contacts that are normally open and close under normal operation.
