All About Time Delay Relays

By: Ariel | 2011-03-28 | Electronics
If you work with electronics, then you are most likely familiar with the different types of relays out there today, but for those who are not, it can be confusing territory to try to learn about. In the case of time delay relays, the basic concept involved in this type of relay is actually fairly simple. Most relays are activated with very low levels of electricity via a control circuit. read more

Practical Applications Of Electric Relays

By: Ariel | 2011-04-18 | Construction
In the old days, relays were required for long distance telegraphs in order to repeat the incoming signal from one circuit and then retransmitting that signal to another circuit. Electric relays are used to switch a mechanism mechanically, but can also be used for a variety of other operating principles. read more

PLC Programming Using Relay Ladder Logic

By: PLC | 2011-01-10 | Training
PLCs (Programmable Logic Controllers) were introduced firstly into manufacturing in 1969, and are now the most widely employed industrial process control technology used today. PLCs are typically used to collect and disseminate information, to sequence robots and other automated devices, and to control conveyor systems in the industrial environment. read more

How Does a Latching Relay Work?

By: Ariel | 2011-04-11 | Tools and equipment
Relays are electromechanical devices that control the voltage of switches. Latching relays send volts to a coil that runs the relay. Unlike other relays, a latching relay does not need unbroken voltage. Taking away the voltage does not place the relay back in its first position. It takes another force action to force it back, such as another operation or a mechanical reset. read more
