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.

From April 25 to 27, at the LogiMAT international logistics trade fair in Stuttgart, Germany, Pilz will present its safe and complete AGV safety automation solutions. 　　At Pilz's booth in Hall 6 – A21, visitors to the show will experience how AGVs are considering ...

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 ...

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 ...

Maintenance method: 1. When selecting the solid-state relay used in the printed circuit board with small current specifications, because the lead terminal is made of high thermal conductivity material, the soldering should be carried out under the condition that the temperature is less than 250 °C and the time is less than 10S.

1. 3-pin relay wiring The common 3-pin relay is the car horn relay. No. 1 is the contact terminal, which connects the load; No. 2 is the common terminal between the contact and the coil, which is connected to the power supply; No. 3 is the coil terminal, which connects the button switch (such as the horn on the steering wheel).

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 ...

The two-handed button is a commonly used safety start device, which is commonly used in punches, presses, cutting machines and other equipment; The purpose is to force the operator to leave the danger zone with his hands when driving the machine, so as not to come into contact with dangerous moving parts and cause safety accidents. 　　The "standard" of two-handed control says ...

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...

Whether Pilz products are to be used in Canada, Italy or China, Pilz customers do not have to worry about the required certifications. 　　The various quality marks on the products show that customers can rely on Pilz, for example in the modular safety relay myPNOZ: 1. By sticking ...

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 ...

Franz Haas, the founder of the Bühler Group, invented the first wafer machine as early as the end of the 40s of the 20th century. Today, its subsidiaries are spread all over the world. In the wafer area of the consumer food division in Leobendorf, 700 employees are engaged in development, design and production, as well as sales, service, maintenance ...

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 ...

In combination with the safety controller, safety sensor technology from PSEN gives you the protection you covered! . Contactless magnetic safety switch PSENmag Magnetic switches can be used to monitor the position of mobile guards and are also suitable for difficult to precisely guide doors, which are susceptible to strong shocks.

Pilz safety light curtains provide cost-effective safety for applications that require body protection. The safety light curtains have a wide operating range of up to 55 m and are ideally suited for the demarcation of external areas. Whether the user wants a single beam or a multi-beam encoder, in the PSENopt and PSENopt II series, there is a choice of 2 ...

When building a safety system, it is particularly important to arrange the components of the safety system reasonably, which determines whether the reliability of the entire system can be guaranteed. Nowadays, with the gradual popularization of safety concepts, people's requirements for safety automation are getting higher and higher, and the scenarios of safety PLC applications are also increasing. ...
