PANTOGRAPH


The pantograph is typically, a single or double wire is used, with the return current running through the rails. Other types of current collectors include the bow collector and the trolley pole.

pantograph (or "pan" or "panto") is an apparatus mounted on the roof of an electric train, tram or electric bus[1] to collect power through contact with an overhead line. The term stems from the resemblance of some styles to the mechanical pantographs used for copying handwriting and drawings.

The pantograph is a common type of current collector; typically, a single or double wire is used, with the return current running through the rails. Other types of current collectors include the bow collector and the trolley pole

PLC COUNTERS

Image
  Counters in PLC programming serve as  invaluable tools for keeping track of various processes and events within industrial automation systems . Their operation revolves around monitoring input signals, which could be anything from sensor readings to specific conditions in the production line. Types of PLC counters There are two main types of PLC counters, the count-up counter, and the count-down counter. For the counter-up counters, we have a counter file name, a counter preset value, a counter accumulated value, a counter count-up bit, and a counter done bit. For the counter-down counters, we have the same bits and values. The only thing that is different is the  counter-down  bit on the output. As you can see below, we have this as  counter-up  bit for the counter-up counter. There are also two internal memory bits of counter overflow and counter underflow which we’ll discuss later in this article. PLC counter values The counter file name is a PLC tag. ...

FLOOD LIGHTNING

Image
  Floodlight  is a broad-beamed,  high-intensity   artificial light . They are often used to illuminate outdoor  playing fields  while an outdoor sports event is  being held during low-light conditions . More focused kinds are often used as a  stage lighting instrument  in live performances such as  concerts  and  plays . Floodlights Association football  field at a sports center illuminated with floodlights. In the top tiers of many  professional sports , it is a requirement for  stadiums  to have floodlights to allow games to be scheduled outside daylight hours. Evening or night matches may suit spectators who have work or other commitments earlier in the day, and enable television broadcasts during lucrative  primetime  hours. Some sports grounds which do not have permanent floodlights installed may make use of portable temporary ones instead. Many larger floodlights (see bottom picture) will ha...
