What is a Pilz relay?
Pilz launched the first PNOZ emergency stop relay on to the market in 1987. The resulting comprehensive range of electronic safety relays for monitoring E-STOP, safety gates, two-hand controls, light barriers etc. is constantly being expanded.
How does a Pilz safety relay work?
The device is designed in such a way that any faults in the input circuit are detected, e.g. contact welding on an emergency stop pushbutton or on one of the safety contacts on the output relay. The safety device stops the device switching back on and thereby stops the activation of relays K1 and K2.
What is Pilz safety PLC?
With the PLC controllers we offer control systems that enable you to control both automation and safety functions within a project. Our PLC control systems are modular, i.e. you can put them together to suit your requirement. You can simply adapt the system structure to suit your requirements.
How does a 2 channel safety relay work?
The Dual-Channel Emergency Stop Safety Relay monitors emergency stop devices, such as palm buttons and rope/cable pulls, and positive-opening safety switches used for guard/gate interlocking. It is designed to connect safety devices, such as interlock switches, to the machine control unit.
Do you have to use a safety relay?
Safety Relays have forcibly guided contacts to prevent NO and NC contacts from operating at the same time during contact welding, which enables detection of contact welding in the Safety Relay itself. This can be used in building safety circuits.
What is the difference between safety relay and normal relay?
A safety relay is used for the combination of switches. Normal relay is used for linkage of contacts.
How does a light curtain safety relay work?
When an object intrudes into the light curtain field-of-view, the light curtain switches off its two PNP outputs (OSSDs). The safety relay responds by opening its two output relays. This removes 24V from the coils of the two safety contactors whose contacts open and remove power to the motor.
When did Pilz invent the first safety relay?
In 1987 Pilz patented the first emergency stop relay to protect man and machine. That was a milestone in safety technology. The safety relays PNOZ quickly progressed to be the world’s most commonly used safety relays. The PNOZ brand is now synonymous with safety relays. PNOZ – The original!
Which is the best safety relay on the market?
To guarantee this protection, for decades Pilz has been developing innovative safety relays that have proven their worth on the market a million times over. For reliable monitoring of functional safety, we offer the safety relay PNOZ and the modular safety relay myPNOZ.
What are the functions of PNOZ safety relays?
The safety relays PNOZ monitor safety functions such as emergency stop, safety gates, light barriers, light curtains, two-hand controls, speed, standstill and much more besides. Every day, PNOZ safety relays prove themselves in millions of applications worldwide.
