Requirements for safety circuits for Pilz safety relays

When building a safety system, it is particularly important to arrange the components of the safety system reasonably, which determines whether the reliability of the entire system can be guaranteed. Nowadays, with the gradual popularization of safety concepts, people's requirements for safety automation are getting higher and higher, and the scenarios of safety PLC applications are also increasing. ...

PNOZ s5 belongs to the PNOZSigma family and is a safety relay with a time-delay function There are 8 terminal blocks on the top and bottom of the module, where: A1 and A2 are the terminal blocks of the module power supply; S11 and S12 are terminal blocks for a set of safety input channels; S21 and ...

The safety switch prevents personnel from entering the hazardous area until all safety conditions have been met Provide bolt switches, safety magnetic switches, safety door lock switches, safety rope pull switches, emergency stop buttons, twisted chain interlocking switches, safety enable switches, safety limit switches, explosion-proof open...

1. High-precision detection: high and low voltage relays can detect high and low voltage signals with high precision, and realize accurate monitoring and control of electrical equipment. 2. Large capacitance switch: High and low voltage relays have good durability and stability when switching high capacitance loads. ...

On fully enclosed rail transit lines, viaducts or tunnels are usually used to avoid the impact of rail lines on the distance, while on non-fully enclosed rail transit lines, the plane intersection between the railway and the distance, that is, level crossings, is more common. In the early stage, rail transit ...

In machinery safety, if it is an access door that prevents entry into the hazardous movement area, it is usually necessary to use a safety interlock switch to realize the "linkage" between the access door and the movement of the hazardous equipment, and when the access door is opened, the dangerous movement stops. In some cases, it is also necessary to prevent the access door from being hit.

For the monitoring of safe protected areas under harsh conditions, such as dust, dirt, rain, light, sparks or shocks, the safety radar sensor PSENradar in combination with the configurable small controller PNOZmulti 2 offers the best solution: in addition to outdoor applications as well as woodworking and ...

1. Some common faults of high-voltage relay coils 1. The common fault cause of the coil is often disconnected: whether the ultrasonic wave is used to clean the high-voltage relay, or whether the overvoltage is added to the coil will also promote the probability of the coil being disconnected. 2 ...

The debut of "Mouse Wire" in the world of automation dates back to 2002 at the SPS trade fair in Nuremberg, where Pilz presented users for the first time with a configurable small safety controller: no need to know a "higher-level" programming language, thanks to the ease of operation, the graphical ...

The fundamental characteristics of safety relays: Feature 1, can be used in some automatic control occasions: safety relay - a kind of equipment that can control safety, this equipment is very easy to use in the automatic control field. Generally, there are emergency stops or safety doors, as well as safety gratings and other input devices.

With the continuous development of the city, the operation technology and demand of rail transit continue to upgrade. Many vehicle manufacturers have set their sights on "automatic guided track systems". Under this standard, the vehicle system has a high degree of automation, and can even achieve full automation and unmanned driving. Eye...

1. The role of intermediate relays It plays the role of converting and transmitting control signals, that is to say, its input signal is the energizing and power-off signal of the coil, and the output signal is the contact action of the intermediate relay. Essentially, it is a type of voltage relay ...

1. After the power failure, the armature cannot be released immediately, which may be due to the stuck movable core, the core air gap is too small, the spring strain and the oil caused by the core contact surface, etc. Universal relay maintenance should be treated differently by the cause of failure, or adjust the air gap to protect it from 0.02 to 0.05 mm, ...

The technology and business of rail freight have remained the same for decades. Until now, in order to test the brakes of freight trains, the crew would walk around the entire train and hit each axle with a special hammer to check the proper operation of the braking system. Rail transport systems in Austria ...

With 168,000 employees in 17 countries, steel giant ArcelorMittal is the world's leading steel producer. The Ghent site in Belgium alone produces more than 6 million tons of steel per year. Its industries mainly include automotive and mobility, construction, energy, and packaging. 　　As the world's leading steel ...

The myPNOZ Creator online tool, the configurator for the modular configurable safety relay myPNOZ, can be used via a PC with an Internet connection and no need for local installation in advance. Find the entrance to myPNOZ Creator on this page and start an extraordinary experience. ...

EU standards have no legal significance in themselves. However, it acquires legal status after publication in the Official Journal of the European Union or citation in domestic laws and regulations. The publication of these harmonized standards will result in a "presumption of conformity". As a result, users who adopt the standard can assume that their actions are in compliance with laws and directives. If it happens ...

1. When the load exceeds the action current, the circuit will be automatically cut off; 2. After the circuit is automatically cut off, the panel indicator light is on, which is convenient for the judgment of the fault part; 3. After troubleshooting, press the red button at the bottom of the panel to restore the normal power supply; 4. For other reasons, the shell ...

Smart factories, Industry 4.0 and autonomous production – the mechanical engineering department is now looking forward to a bright future. The pace of innovation and ever-shortening development moments are playing an increasingly important role in the global race. To streamline the engineering process and add reusability to individual components, the regulations ...

1. Rated working voltage It refers to the voltage required by the coil when the relay is working normally. Depending on the model of the relay, it can be either AC voltage or DC voltage. 2. DC resistance Refers to the DC resistance of the coil in the relay, which can be passed by a universal meter.
