Whether you control a process with a computer, process control system, PLC, or a field device, a surge protector can eliminate or reduce the risk of damage to sensitive electronics caused by transient overvoltage. In this article, we outline four surge protection solutions.
If you want to establish internal food traceability in a meat processing plant, you face a number of challenges: Diverse processes, harsh environmental conditions, hygiene requirements and different transport routes demand a flexible and at the same time reliable technology. Industrial RFID offers a solution for this and also, depending on the application, other additional benefits.
The fieldbus terminator, also referred to as a terminator, is a component in a fieldbus system. This terminator takes the shape of a series connection featuring a 1 µF capacitor and a 100 Ω resistor. The main task of the fieldbus terminator is to transform the data signal transmitted as a current change into a voltage change that can be detected by all nodes.
RFID is one of the most versatile technologies in industrial automation. Whatever industry you may be thinking of—it is highly likely that RFID will be used there. We have compiled ten RFID applications that give you ideas for possible applications and demonstrate the advantages of this identification technology.
RFID tags carry information on a certain object or transport container. The size of an RFID tag can vary from the dimensions of a match head to a brick. While some tags are used simply as an attachable ID for an object, others carry a variety of different attributes relating to the object.
To enable noncontact data exchange via an RFID system, radio waves are used for communication. Depending on the application requirements, RFID systems utilize different frequency ranges. As a general principle, most RFID systems use the so-called ISM bands (Industrial, Scientific, and Medical Band) in order to avoid cross-talk of radio systems and ensure reliable data information exchange. Commonly, passive RFID systems use either low frequency (LF), high frequency (HF), or ultra-high frequency (UHF).
