Relays are switches operated by electrical signals. They are often straightforward mechanical switches or complex semiconductor arrays without having moving parts, nonetheless they all operate by opening or closing a switch when a signal is received. These simple items are critical components within an equipment protection plan.

Common Relays: Breakers and Surge Protectors

Every electrical system has circuit breakers made to shut down power when electrical faults are detected. These simple relays are a critical safety feature as without them a minor fault could cause significant equipment damage or damage to workers. Most people are acquainted with these switches from your electrical panels in their own homes. Circuit breakers really should not be confused with fuses which aren't switches but rather connections deliberately meant to be weak so they really fail predictably in the event of overvoltage.

Another familiar form of relay is the surge protector. Like circuit breakers these relays are created to shut down power in case of dangerous voltage spikes that can from lightning strikes and other power surges.

Other Types of Protective Relays

The versatility of relays gives them other protective uses. Essentially any characteristic that could be measured electronically can be used to trigger a relay and initiate or stop equipment.

Certain kinds of flow and level switches which can be driven electronically are used to protect pumps from damage. A pump that continues operating even without the liquid can overheat and breakdown far more quickly than the usual human operator can shut it down. Relays that monitor fluid level and flow de-activate the pump before liquid supply ends.

Temperature relays shut down equipment before overheating or energize thermal tape to safeguard pipes from freezing temperatures. Optical relays detect the presence smoke and sound alarms to warn people of the possibility of fire.

Relays Improve Equipment Efficiency

Relays allow machinery to automatically start and off as a result of changing conditions, that may do more than just protect equipment from damage. A fairly easy example is a thermostat set to activate heating or cooling as temperatures move away from comfortable ranges.

Plants with critical power needs use relays to react to power failures. When external power fails, these switches automatically activate batteries or generators to deliver supplementary power. This could happen so quickly there is no interruption of power in any way.

Many offices are installing automatic light switches so that you can conserve energy. When it detects people in the area, generally with motion sensors, the lights think about it and when the people leave the lights automatically turn off. These can installed to manipulate anything from an entire building's lights to individual fixtures in cubicles.

Relays happen to be a component of everyday industrial and business life, but information mill finding creative new ways to use these switches to protect equipment and improve operational efficiency.
