Pierre Switches – An introduction to the basics of safety switches

In the safe configurable small controller series PNOZmulti 2 from Pilz, a new stand-alone base module PNOZ m C0 is now available. PNOZ m C0 has the structural characteristics of a safety relay, but it is just as powerful as a safety controller. It offers 8 ...

Since its launch, Pilz's flagship product, the configurable and safe small controller PNOZmulti, has been impressed by users for its robustness, flexibility and ease of operation. PNOZmulti Configurator as a configuration tool for the safe small controller PNOZmulti ...

1. Selection of relay coil application power supply Under normal circumstances, most of the relays of direct current are selected in the circuit design, and the types of power supplies used in relays can also be considered according to the characteristics of the control circuit. Secondly, it is necessary to think about the power consumed by the relay, and assume that the relay coil is supplied ...

How do you grasp the issues of employee protection, responsibility protection, work efficiency, and data protection? How can you improve quality and at the same time prevent machines from being tampered with? How can data and employees be protected in equal measure? Through I.A.M. (Identification and Access Management) "...

The most common ones are the following: (1) Contact failure 1. The phenomenon that cannot be disconnected due to mechanical occlusion of the contact (the needle-like protrusion formed on the contact and the pit biting each other), fusion welding, or cold welding. 2. Due to the contact resistance becoming large and unstable, the circuit cannot be normal ...

Recently, Pilz won the China Machinery Industry Science and Technology Award jointly issued by the China Machinery Industry Federation and the China Mechanical Engineering Society, in recognition of Pilz in the "Machinery Safety Hazardous Energy Control Method Locking/Listing (GB/T33579-2017 Standard Number) Standard Formulation, Application and Publicity...

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 ...

Pilz safety relays consist of several relays and circuits to compensate for each other's abnormal defects and achieve the full functionality of a relay with low misoperation or even correct relays. The lower the fault value and fault, the higher the safety factor. In order to prevent unavoidable misoperation or natural wear and tear of the machine, it should also be ...

When using Pilz safety relays, it is necessary to pay attention to the correct way to use them. The key to the correct use of safety relays is to protect the wiring method of the input circuit. In general, the wiring method of the safety relay is divided into three types.

Whether on the assembly line or on the machine, the safety rope pull switch is a proven and reliable solution for triggering an emergency stop function from any point on the pull rope to shut down dangerous work processes. Pilz's rope pull switch PSENrope is available in rope lengths up to ...

1. The relationship between the specifications of the relay and the installation location For different star/triangle control positions, the specifications of the selected thermal relays are also different. As shown in Figure 1, the current setting value of the selected thermal relay is equal to the rated current value of the protected motor. In Fig. 2, the selected thermal relay ...

With the rapid development of industrial technology, on-site equipment is also developing towards a high degree of integration and automation. But no matter how the technology develops, behind the dazzling technology, the basic common equipment is always a solid backing. The hydraulic press is one of the old industrial basic equipment, and it is almost ...

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 ...

Radar technology is ubiquitous in our lives, from the surveillance radar on the car to the safety radar on the industry, the purpose is to make the dangerous equipment have the ability to detect the surrounding moving objects, and effectively remind and brake when the moving objects are found to be approaching. The Pilz Safety Radar has been ...

With the increasing functional requirements of industrial production, the continuous optimization of process levels and the escalation of the complexity of production conditions, systems that effectively record and manage relevant data are particularly important for machine safety, especially for production safety. PITreader Authorization ...

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, ...

Visualization solution PASvisu with OPC UA interface Pilz is expanding its web-based visualisation solution PASvisu: From the new version 1.3 onwards, the OPC UA interface can be connected to the small controller PNOZmulti and other control systems. Use...

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. ...

At the SIAF Guangzhou Automation Exhibition, which opened on March 10th, Pilz once again brought new automation solutions to visitors under the concept of "WeAutomate Safely". The exhibition ...

When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the electrical appliances that make the output circuit to be controlled on or off can be divided into two categories: electrical quantity (such as current, voltage, frequency, power, etc.) relays and non-electric (such as temperature, pressure, speed, etc.) relays.
