What Are Variable Message Signs? Variable message signs—also known as changeable or dynamic message signs—are electronic signs commonly used by traffic authorities on roadways to convey important information to motorists. They can be used to indicate speed limits, provide traffic or accident updates, relay public safety messages, or spread local, state, or national news. Some…
The Importance of Oven Igniters in Gas Ovens
The Importance of Oven Igniters in Gas Ovens Gas ovens came into usage in the mid-1800s and remain popular to this day. Early-model gas ovens had to be fired up with a match, and this functionality eventually evolved into the pilot light. In those early model ovens, sometimes user or mechanical error could cause the…
The Importance of Time Delay Relays in Burglar Alarm Systems
The Importance of Time Delay Relays in Burglar Alarm Systems Many homeowners install burglar alarms system in their homes to help keep their family members and possessions safe. When activated, the system provides alerts if and when intruders enter the residence as well as if and when a fire, gas leak, or other potentially dangerous…
What is a One Shot Timer and Why Are They Important?
Optimize Operations With a One-Shot Timer A one-shot timer is a type of timer incorporated in a time delay relay. All relays send signals that initiate or halt operations in connected machines and systems. However, time delay relays have a delay cycle, which defers the delivery of the trigger for a set period of time….
This is Why You Need Normally Open Relays
Understanding Normally Open Relays Relays are electrical switches that rely on electromagnetic mechanisms to convert small electrical inputs into larger outputs. The input of electrical current activates the electromagnets, forcing them to open or close the existing electrical circuit with regard to their rest state. This action may then produce a single output signal or…
The Little Relay in Commercial Coffee Machines Make a Huge Difference
Why are Time Delay Relays So Important for Coffee Makers?: A Guide to the Coffee Maker Relay Though there are up to 100 types of coffee plants, most of us come to know coffee as whole beans or grounds that we purchase at the store. Whether we order from a coffee shop or hit the…
The Importance of High-Quality Time Delays for Air Conditioning Systems
Understanding Normally Closed Delay-on-Break TDRs for Air Conditioning Systems Air conditioning is a cooling method that removes heat and reduces humidity in an enclosed area to create a comfortable environment. Air conditioners provide air treatment by transporting warm air outdoors and replacing it with cooler refrigerated air. Air conditioning systems come in a variety of…
Automobile Turn Signal Flashers
Turn-signal indicators—also known as blinkers or flashers—are perhaps one of the most critical safety features on automobiles today. Automotive flashers are used in turn signals as well as a hazard or warning flashers. They help to communicate the intentions or actions of one driver to other drivers and pedestrians around them. The most common form…
What Are Normally Closed Relays?
Normally Closed Relays Time-delay relays are essential components of a variety of machines and devices. These systems convert electrical currents from different voltage levels to ensure the equipment receives the right amount of power at the right time. Many different types of time-delay relays are in use today, including interval-on-operate, flasher, normally open, and normally…
What is a Relay and Why Are They So Important?
Relays Converting a small electrical input into a high-current output is no easy feat, but this task is necessary to efficiently operate a wide range of standard appliances and vehicles. Many circuits achieve these conversions through the use of relays, which are indispensable in all kinds of electronic equipment. What Is a Relay? Relays are electric…
