Machinery safety is all about mitigating risks & hazards. Firstly by physical guarding, and where that isn't practical the use of devices which detect unsafe conditions and either prevent the process from starting, or safely stop the process. At the heart of this are safety relays and controllers which monitor safety sensors, switches and other safety circuits continually ensuring any unsafe conditions are spotted and the process or machine stopped.
The PSR classic safety relays for single or two-channel emergency stop (E-Stop) and safety door monitoring from Phoenix Contact can be connected easily without the need for additional settings on the relay.
A family of slender units, providing two safety contacts in a 17.5mm, and three safety contacts in a 22.5mm wide housing with 1 or 2 safety inputs.
Explore the XPS range of safety relays to find options covering all applications and safety functions.
The market leading range of safety relays from the company that pioneered the creation of the modern safety relay.
The current generation of PNOZ safety relays, slimmer and offering more functions from a smaller range simplifying relay selection.
A family of safety relays with either Single or Dual channel operation, and designed to mirror the footprint and features of a well-known safety relay which is no longer manufactured.
The PNOZMulti Mini provides full configuration of safety functions and logic from up to 20 safe inputs allowing complex safety monitoring and control from a single controller.
Explore our range of safety controllers and configurable safety relays from Pilz, Rockwell Allen-Bradley, ABB, Phoenix Contact and Schneider Electric.
A safety relay is an automation device that monitors for potential errors or faults in machinery or plants and works to prevent injury and reduce risk. If an error occurs, the safety relay initiates the appropriate response to reduce the risk and bring the environment back to a safe, acceptable level.
