What is cable screen? A protected cable or screened cable is an electrical cable connected by a prevalent conductive layer of one or more isolated wires. The cover may consist of braided copper threads (or other metals such as aluminium), an unbraided copper cable loop wrapping, or a conductive fabric coating. This cover is usually …
What are Armoured cables? Armoured cable is the name given to any electrical cable built with an armour of aluminium wire or steel wire armour. The armour sits under the cable sheath to protect the driver and isolate the layers. Why armoured cables are used? For use outside or in direct burial projects, the electrical …

The performance of cable screen depends on their construction. There are different types of cable screens available depending on the applications, specialized screen constructions, such as optimized or multiple braids You can also run an unscreened cable in a shielded conduit, in a separate braided screen, or wrap it with screening or permeable material. For …
What is an Antenna? An antenna is a circuit element that provides a transition from a guided wave on a transmission line to a free space wave, and vice versa. It is made of a thin electrical conductor to efficiently radiate electromagnetic (EM) energy. Antenna characteristics are the same, whether a transmitting antenna or a …
WiFi 802.11: The 802.11 standard specifies requirements in the 2.4 GHz and 5 MHz ISM bands for wireless Ethernet devices using DSSS. This standard is popularly known as WiFi (wireless fidelity short). Since the late 1990s, WiFi devices have been on the market, with several 802.11 standards emerging, from 802.11a to 802.11n. The most frequently …
Instrument cabling usually runs from the control room to the plant area (either below or above ground) in multicore cables and then from field junction boxes in single pairs to field measuring or actuating devices. Cabling requirements: They should be kept as short as possible. They should not cause any obstruction to prohibit access to …
Common Industrial Protocol is an ODVA-supported open industrial protocol. It is used and used in EtherNet / IP, DeviceNet, CompoNet and ControlNet for industrial automation applications. It includes a full set of messages and services for collecting automation applications for manufacturing–control, safety, synchronization, movement, configuration, and information. It permits users to integrate these manufacturing applications …
SCADA (Supervisory Control And Data Acquisition) is a system that refers to a combination of telemetry and data acquisition. This consists of gathering information, transferring it back to the control center, carrying out the necessary analysis and control, and then displaying this data on a number of display operators SCADA protocol: The Survalent SCADA feature …
RS232 and RS485 are standards for data cables. To exchange data between nodes in a network, the most commonly used tools are line controllers and receivers. RS232: The RS-232 serial port, present in all current computers, is the most commonly used way to perform data transmissions between computers. The RS-232 consists of a 25-pin type …
Ethernet refers to the local area networks and devices that was defined by the Institute for Electrical and Electronic Engineers (IEEE) under the IEEE 802.3 standard that defines the CSMA / CD protocol. Ethernet is popular because it allows a good balance between speed, cost and ease of installation. This is currently used for approximately …
