Safety Doesn’t End with Relays: The Broader Role of Monitoring and Output

While safety relays handle many critical functions such as emergency stops and guard monitoring, they represent only one part of an effective safety system. The safety monitoring and output range at Venus Automation provides tailored solutions to meet the needs of diverse machines and projects.

A key component in modern safety systems is the safety PLC. These programmable devices allow custom safety logic, with flexible input/output terminal assignments. Venus Automation offers a variety of models, including the MOSAIC PLC from Reer, Samos PLC from Wieland, and GEMNIS PLC from Pizzato—each delivering advanced and reliable safety functionality.

Where complex programmability is unnecessary, alternative options such as the safety relay range are available. This includes standalone relays, time-delay relay, speed-monitoring relay, standstill monitoring and timer, PCB relay, relay expansion modules, and control relays like the emergency stop relay, safety edge relay, light curtains relay, and two-hand control relay. These options provide effective and application-specific safety responses.

Essential manual inputs such as the emergency stop remain integral to any safety architecture, despite lacking an automatic safety input. Venus Automation supplies complete solutions including emergency stop accessories, pushbuttons, two-hand stops, and specialized devices like the rope pull emergency stop. For modern installations, wireless safety systems, including wireless emergency stop units, remote controls and accessories, are also available.

Critical integration elements such as contact blocks are supplied to ensure seamless circuit connections. Additional safety monitoring components include the safety encoder, which monitors motor speed, and interlock devices such as tongue solenoid interlock switch and electro-magnetic switches. For more complex safety guarding, multifunctional gatebox units provide a consolidated interface, easily mounted on protective enclosures like concertina guards.

Access restriction and control can also be achieved through electronic key systems, ensuring machinery operates only under authorized conditions. Finally, for output-side protection, safety contactors and pneumatic safety valve solutions are available to ensure reliable machine stoppage when hazardous conditions are detected.
