How Pilz replaces the safety switch

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 ...

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 ...

An autonomously running burner management system has a complex structure and must comply with many international standards. Due to the high level of danger, strict safety regulations need to be applied to avoid the presence of unburned fuel in the combustion chamber. Pilz has a safe burner management system specifically tailored to these requirements. ...

ACMI S.p.A. is an Italy company specializing in high-tech bottling and packaging lines. Based in Fornovo Taro, in the province of Parma, Italy, the company initially produced palletizers and depalletizers for the food and beverage industry, and later specialized in all packaging processes. For...

1. Contact failure (1) The phenomenon that cannot be disconnected due to mechanical occlusion of the contact (the needle-like protrusion and pit formed on the contact bite each other), fusion welding, or cold welding. (2) The contact wear of the relay is caused by the absence of arc extinguishing devices or measures, or improper parameter selection, ...

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. Determine the voltage range that needs to be regulated: First of all, you must clarify the voltage range you need to regulate, as well as the specifications of the high and low voltage relays and the voltage range that can be adjusted. If there is no clear scope and specifications, you can check the relevant manuals of high and low voltage relays or consult the equipment manufacturer.

In the process of adjustment, cleaning, maintenance and repair of mechanical equipment, the unexpected start of equipment due to various reasons is one of the most typical accident causes. Many companies may also be struggling with how to effectively control unplanned start-ups during maintenance. In order to have ...

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. The security door can also be called the anti-theft door, and the safety door switch, as the name suggests, is an automatic inductive control switch to ensure the safety of the door, and the opening and closing of the door needs to be detected by it to open and close. For example, this kind of safety door switch will be used in the community or factory, traffic, etc., which is conducive to monitoring ...

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 ...

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's modular safety relay myPNOZ has received a lot of attention and acceptance since its introduction. It has been nominated for the Hermes Award, the Germany Innovation Award (GIA) and the Red Dot Design Award. This safety app, which can be customized and mass-produced according to user requirements, can be customized according to user requirements.

On March 1, 2023, the National Printing Machinery Standardization Annual Conference and the First National Coating Machine Standardization Annual Conference were held in Yiwu, Zhejiang. The meeting was guided by the Standardization Administration of the People's Republic of China, the China Machinery Industry Federation, and the Yiwu Municipal People's Government.

Features of the safety door switch: The safety gate switch is composed of two independent parts: the switch body and the operating part of the switch. When the safety door is opened, the switch actuator is pulled out of the switch body and the normally closed contacts in the switch are disconnected by a mechanical rebound device. While...

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 ...

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

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 ...

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 ...

From June 12 to June 16, 2023, Pilz will be present at the THERMPROCESS trade fair in Düsseldorf, Germany, at booth B10 in Hall 9. Germany Düsseldorf Thermprocess is Germany most important trade fair for industrial furnaces and heat treatment ...
