Peel magnetic relays - what are the connection methods of relays?

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.

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 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, the inaugural meeting of the Youth Safety Expert Working Committee of China Machinery Industry Safety and Health Association and the first China Equipment Manufacturing Youth Safety Expert Forum were held in Chengdu, Sichuan.

The naming of solid state relay models has not been unified, and the following conditions should be considered when selecting the manufacturer's manual. (1) Rated input voltage Refers to the maximum allowable effective voltage of a steady-state resistive load that can be withstood under a given condition. When used for inductive loads ...

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) Use The high-voltage load switch is an electrical appliance with a function between the high-voltage circuit breaker and the high-voltage isolation switch, and the high-voltage load switch is often used in series with the high-voltage fuse; It is used to control power transformers. The high-voltage load switch has a simple arc extinguishing device, because it can turn on and off ...

Power supply: AC: Terminals A1 and A2 are connected to the power supply, and the ground wire is connected to the protective ground. DC: A2 is connected to the ground terminal of the power supply. Start-up loop: Auto-start: S13-S14 shorted. Manual monitoring start-up mode: S33-S34 ...

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

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.

1. Classification by use In terms of use, the classification of relays can be divided into two types: control relays and protection relays. In the meantime: thermal relays, overcurrent relays, and undervoltage relays are all protective relays. And moment relays, speed relays, intermediate relays ...

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 ...
