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".
At the trade fair, Pilz will be presenting its star products: safety relays, a benchmark in safety technology, PNOZmulti controllers, a pioneer in configurable safety technology, and an automation system PSS4000 for Industry 4.0.
PNOZ safety relays monitor emergency stop buttons, safety gates, light barriers, light barriers, two-hand controls, pressure-sensitive carpets, speed and stationary and many other safety functions.
The configurable small controller PNOZmulti is mainly used to implement a wide range of safety functions, allowing users to protect man and machine simply and flexibly.
With PSS4000 automation system, the user can individually configure it to meet the actual requirements. Users can configure the system with a wide range of performance classes, a wide range of I/O modules, and visualization and engineering software.
Pilz is showcasing complete solutions for motion drive technology, from controller operation to highly dynamic drives. Pilz's servo drive technology has an open, modular drive concept, which makes it easy to integrate individual components or complete systems into existing system environments, regardless of whether the user's needs are for a new installation or a retrofit.
Pilz offers a wide range of safety sensors that comply with international standards and have been tested by certification bodies. Sensors on display include: the safety laser scanner PSENscan, which enables a wide range of applications in the monitoring range of fixed and moving areas; PSENopt encoders can be used in all industrial sectors where the concept of barrier-free safety needs to be implemented; and PSENmat, the world's first pressure-sensitive safety mat with integrated switching.
As a specialist in safe automation, Pilz has extensive experience in the development of safety-focused automation solutions and is able to provide users with individualized overall technical solutions and service support to protect people, machines and the environment.

The Pilz automation system PSS 4000 assists in railway braking tests
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 ...

Peel magnetic relays – the difference between solid state relays and mechanical relays
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...

Peel magnetic relays – a common fault of electromagnetic relays
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, ...

The working principle and characteristics of Pilz safety relays
Pilz safety relays generally consist of an iron core, a coil, an armature, a contact reed, 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. Under the action of electromagnetic attraction, the armature overcomes the pulling force of the return spring and sucks in the iron ...

Common faults with Pilz safety relays
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 ...

REASONS FOR USE OF PILZ SAFETY RELAYS
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 ...
