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 ...

Selection and features of Pilz safety relays: 1. Understand the necessary conditions first The power supply voltage of the control circuit, the maximum current that can be delivered; voltage and current in the controlled circuit; How many sets of contacts and what form of contacts are required for the controlled circuit. Choosing the following ...

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 ...

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.

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.

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 larger and unstable, the circuit cannot ...

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 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...

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 ...

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 ...

1) Larger shape: The safety relay is different from the ordinary relay, and the safety relay is larger. 2) Modules instead of components: A safety relay is a module, not an electronic component like a normal relay. 3) Red and yellow: The safety relay has ...

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.

Generally speaking, the input control voltage of the solid state relay is 3.2-32V. The control current is 5-30mA.Usually the SSR input circuit of 1-2 is not a constant current source circuit, and the input control voltage is 4-16V. The control current is 5-20mA, and the SSR input circuit with the larger rated current is connected to the constant current source ...

Applications for Solid State Relays (1) The recommended value of the foreign SSR trigger signal (i.e., the current through the light-emitting tube) is 10mA DC, and the recommended value of the domestic SSR trigger signal is 12-25mA DC. (2) Multiple SSRs can use the same trigger signal, which is common in the control of three-phase AC loads.

Maintenance method: 1. When selecting the solid-state relay used in the printed circuit board with small current specifications, because the lead terminal is made of high thermal conductivity material, the soldering should be carried out under the condition that the temperature is less than 250 °C and the time is less than 10S.

Franz Haas, the founder of the Bühler Group, invented the first wafer machine as early as the end of the 40s of the 20th century. Today, its subsidiaries are spread all over the world. In the wafer area of the consumer food division in Leobendorf, 700 employees are engaged in development, design and production, as well as sales, service, maintenance ...

On machines with electrosensitive protective devices (e.g. laser scanners or light curtains), safety is ensured by the distance between hazardous movements and electrosensitive protective devices. Where there is intervention/access to the danger zone, there will be no more runaway movements. Overrun is a dangerous movement that stops after a shutdown ...

PILZ PILZ SAFETY RELAYS ARE THE MAIN COMPONENTS FOR CONTROL CIRCUITS AND MONITORING AND PROTECTION SYSTEMS FOR ELECTRIC LOCOMOTIVES. WHEN THE ELECTRIC LOCOMOTIVE IS RUNNING, WHEN THE MOTORS, ELECTRICAL APPLIANCES OR CONNECTION LINES IN THE MAIN CIRCUIT AND AUXILIARY CIRCUIT FAIL, THE FAULT CAN BE REPLACED BY THE PILZ SAFETY RELAY OF THE CORRESPONDING MONITORING AND PROTECTION SYSTEM.

1) The installation of the switch panel should be after the installation of the lamp, and the switch must be connected in series on the live line; Application of sealed or protected sockets in wet locations; The allowable deviation of the verticality of the panel is not more than 1mm; The gap between the panels installed in rows should not be greater than 1mm. 2) Where the socket must be facing the switch panel ...

The naming of solid state relay models has not been unified, and the following conditions should be considered when selecting the manufacturer's manual.
