Pilz releases version 1.23 of the automation system PSS 4000

1. The effect is not the same: The primary effect of the relay is: signal detection, transmission, conversion or disposal, the circuit current it is on and off is generally small, and it is generally used in the control circuit to control weak signals. The primary effect of the contactor is to turn on or off the main circuit. Host...

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 ...

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.

There are 3 basic forms of relay contacts: (1) The two contacts are disconnected when the dynamic type (normally open, H-type) coil is not energized, and the two contacts are closed after the energizing is applied. It is represented by the pinyin prefix "H" of the word "合". (2) Dynamic breaking type (normally closed, D-type) coil is not energized when the two contacts ...

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 ...

With the progress of the industrial level and the improvement of people's safety awareness, more and more attention has been paid to the safe operation of equipment in the workshop. As a professional supplier of safe automation solutions, Pilz's safety products are used in a wide range of industries. Configurable safety control system PNOZmulti ...

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, ...

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 ...

As one of the core equipment of smart factory logistics, automatic guided vehicles (AGVs) play an increasingly important role in the factory logistics automation system. They travel through the warehouse and complete the handling task efficiently, which brings great convenience to the production, but also has certain safety hazards.

1. Determine whether the safety relay itself is faulty: 1. Separate from the three circuits of short-circuit S10/S12, S11/S12, S21/S22. 2. Turn on the 24V power supply (A1 is positive, A2 is negative), and the Power light should be on at this moment; 3. Reset the S33/S34 terminals, and the K1 and K2 lamps ...

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 ...

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 ...

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 ...

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 ...

In addition to the usual emergency stop monitoring, safety gate monitoring, light barrier monitoring and two-hand button monitoring, the safety relays of the PNOZsigma family are also functional, as well as safe speed monitoring, safe braking and braking monitoring. Voltage monitoring safety relays are also one of its features. PNO ...

Thermal energy utilization is very common in today's industrial fields, such as metal thermoprocessing, food baking, paint drying, grain drying, glass/plastic melting, fiber hair removal, etc. The sources of heat energy used in these fields are usually in 2 forms: 1 is the conversion of electrical energy into thermal energy ( ...

Industrial security has become an integral part of automation, but with new requirements and specifications, manufacturers, integrators, and operators are faced with the question of how their employees can meet the new challenges. In response, Pilz has launched a new safety training course that can help students learn ...

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.

There are many applications that you can achieve with PMC EZ servo motors. Their compact design is a convincing feature that also makes them ideal for space-critical applications. In addition, you benefit from high dynamics and low cogging torque. 　　Servo motor PMC EZ ...

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 ...
