Peel magnetic relays – Precautions for the selection of relay modules

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 ...

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.

The tightly meshing beam field of the safety light curtains PSENopt and PSENopt II is ideally suited for all applications where hand protection is required. By placing the safety light curtain close to the danger zone, the operator can be optimally protected and the workflow will not be interrupted, making it ideal for spaces with ...

From 8 to 10 November 2022, at the SPS trade fair for intelligent production solutions in Nuremberg, Pilz will focus on automation solutions for safety and industrial security in plants and machinery under the theme "Safe and reliable". 　　Safe and cost-effective control ...

Automated Guided Vehicle, abbreviated as AGV, also commonly known as AGV trolley, refers to a transport vehicle equipped with electromagnetic or optical automatic navigation devices, which can drive along the specified navigation path, and has safety protection and various transfer functions. Due to its flexibility, the degree of intelligence ...

When the input quantity (such as voltage, current, temperature, etc.) reaches the specified value, the electrical appliances that make the output circuit to be controlled on or off can be divided into two categories: electrical quantity (such as current, voltage, frequency, power, etc.) relays and non-electric (such as temperature, pressure, speed, etc.) relays.

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 ...

When part of the production line no longer meets the current production needs, do you choose to buy new equipment or modify old equipment? Scheucher, a hardwood flooring manufacturer based in Austria, was faced with such a choice not so long ago. In Scheuch ...

Wiring method of time relay 1. Control wiring You think of it as a DC relay. 3. 7 is used to connect to 12V control voltage; 2. 7 is used to connect to 24V control voltage. 7 of them are used as the negative electrode of direct current, which is connected to the neutral line when used. 2. Connect to a 220V live wire. 2 ...

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 ...

1. Check the alarm cause of the relay, if there is a fault, reset the relay urgently, and replace the relay in time. 2. Check whether there is a protection alarm in the control system, if there is a protection alarm, the cause of the alarm will be eliminated, and the protection alarm system will be reset according to the corresponding steps. ...

The automation system PSS 4000 offers new features in the new version 1.24. Here's what you need to know: 　　New data types FIXED and LFIXED The data types FIXED (a fixed digit with 6 decimal places) and LFIXED (a fixed number with 11 decimal places) are now ...

1. The shape is larger The dimensions of safety relays are different from ordinary relays, and safety relays are larger. 2. Modules instead of components A safety relay is a module, not an electronic component like a normal relay. 3. Color Quiet...

The "Safety Standardization" theme exhibition organized by the China Machinery Industry Safety and Health Association and the National Machinery Safety Standardization Technical Committee was unveiled at the China Yiwu International Commodities (Standards) Expo held from November 24 to 27, 2022. Automation specialist Pilz was invited to participate in the exhibition to demonstrate ...

1. The fastener itself needs to be reliable and stable enough. 2. Need to rely on special tools to remove, such as hexagon screws, star screws, etc. Phillips/slotted screws are not recommended, as in some cases they can be easily fitted with fingernails or on the go.

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.

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...

With the advancement and vigorous development of the concept of Industry 4.0, machinery and equipment are assisting or replacing personnel to complete the product production and processing process more efficiently and with high precision, and at the same time, the high-speed moving parts of machinery and equipment may cause different degrees of injury to operators. Countries around the world ...

1. Physical location of the installation – "out of reach or out of sight" Consider installing the component in a place that is out of the reach of personnel, or directly outside the interlock switch as a protective cover to prevent disassembly or movement, as shown in the figure, whether it is a mechanical interlock on the left, or a non-...
