Peel magnetic relays - characteristics and principles of use of safety relays

1. Breaking and closing. Because it has a certain arc extinguishing ability, it can be used to break and close the load current and the overload current of a certain multiple (usually 3-4 times) of the small stem; It can also be used to break and close a no-load transformer with a larger capacity than the disconnector allows, a longer no-load line ...

Pilz's safety validation services for plants and machines can now be customised to suit your needs, choosing between three different validation levels.

As one of the core equipment of intelligent factory logistics, mobile handling robots play an important role in the factory logistics automation system. The AGV is equipped with an automatic guided vehicle, which can ensure that the system can be flexible and changeable along the ...

1. 3-pin relay wiring The common 3-pin relay is the car horn relay. No. 1 is the contact terminal, which connects the load; No. 2 is the common terminal between the contact and the coil, which is connected to the power supply; No. 3 is the coil terminal, which connects the button switch (such as the horn on the steering wheel).

In the context of industrial automation, the term "safety" refers to the functional safety of equipment, which means that people and the environment are protected from damage from foreseeable coercion from machines, and the residual risk is more or less always present, but the residual risk cannot exceed the acceptable level. Through the use of security relay ...

1. After opening, establish a reliable insulation gap to separate the equipment or line that needs to be overhauled from the power supply with an obvious disconnection point to ensure the safety of maintenance personnel and equipment. 2. According to the operation needs, change the line. 3. It can be used to divide and combine small currents in the line, ...

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 ...

Why can't ordinary relays be used in safety-related applications? Ordinary relays use the mechanical action of coils and metal contacts to switch loads. Metal contacts may be fusion welded due to repeated operations. Once this happens, the machine will also be ...

1. The structure/working principle of the two is different Mechanical relays consist of an iron core, coils, and contacts. When the coil is energized, the current in the coil generates a magnetic field that makes the contacts act, thus completing the working principle of the mechanical relay. Solid state relays are made up entirely of electronic components. That...

1. When the emergency stop is lifted, the machine cannot be suddenly restarted 2. In case of failure of the machine safety circuit, the power supply of the machine can be stopped 3. When the safety circuit fails, the machine can no longer be started Confirm safe input such as safety switches, light curtains, etc.

With the increasingly widespread use of industrial robots, the trend of China's manufacturing industry to a higher degree of automation has been bright, and the transformation and upgrading of China's manufacturing industry is on the way. The emergence of collaborative robots means that more intelligent robots will become the future intelligent system of China's manufacturing enterprises.

1. Presses = inflexible? In the past, presses were often labelled as "sluggish", "inflexible" and "high-risk". With the development of technology, safety solutions for presses are emerging one after another, and the safety of presses is greatly improved. In the event that security is ensured...

At the Hannover Messe 2022 at the Industrial Fair (30 May 2022 * 2 June), Pilz will be presenting complete automation solutions including security and industrial security that can be automated independently and flexibly. Visitors can enjoy a tour of the Peel ...

(1) Use The high-voltage load switch is an electrical appliance with a function between the high-voltage circuit breaker and the high-voltage isolation switch, and the high-voltage load switch is often used in series with the high-voltage fuse; It is used to control power transformers. The high-voltage load switch has a simple arc extinguishing device, because it can turn on and off ...

1. Check the alarm cause of the relay, if there is a fault, reset the relay urgently, and replace the relay in time. 2. Check whether there is a protection alarm in the control system, if there is a protection alarm, the cause of the alarm will be eliminated, and the protection alarm system will be reset according to the corresponding steps. ...

The development of IT technology is changing all walks of life, automation is no exception, the degree of networking of production equipment and the use of standard protocols such as Ethernet for physical transmission of data has greatly increased, standardized protocols such as OPC UA allow access to controllers through IT systems, making data communication changeable.

PILZ SAFETY RELAYS GENERALLY CONSIST OF AN IRON CORE, COILS, ARMATURES, CONTACT REEDS, ETC. As long as a certain voltage is added to both ends of the coil, a certain current will flow through the coil, resulting in an electromagnetic effect, and the armature will overcome the tensile force of the return spring under the action of electromagnetic force attraction to ...

The "Safety Standardization" theme exhibition organized by the China Machinery Industry Safety and Health Association and the National Machinery Safety Standardization Technical Committee was unveiled at the China Yiwu International Commodities (Standards) Expo held from November 24 to 27, 2022. Automation specialist Pilz was invited to participate in the exhibition to demonstrate ...

Pilz safety light curtains provide cost-effective safety for applications that require body protection. The safety light curtains have a wide operating range of up to 55 m and are ideally suited for the demarcation of external areas. Whether the user wants a single beam or a multi-beam encoder, in the PSENopt and PSENopt II series, there is a choice of 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 ...
