Eaton Time Delay Relays

More Information about Eaton Time Delay Relays

Another advantage of Eaton time delay relays is their reliability. They are designed to operate in harsh environments and to withstand high levels of vibration and shock. They are also designed with features such as surge protection and noise suppression to prevent damage from electrical surges and interference.

Eaton time delay relays are designed to meet or exceed industry standards for safety and performance. They are tested to ensure they can withstand extreme temperatures, humidity, and other environmental factors, and are certified to meet various international standards, such as UL, CSA, and CE.

Time Delay Relay Basics

ON Delay Relays 

When the coil in a normal relay is energized, the contacts are instantly closed, allowing the current to pass through. When the coil in an ON delay relay is energized, the contacts are delayed for a given period of time, before they close. A common use for an ON delay relay is to reduce the inrush current when powering on several devices at once. The ON delay relay can power on one device slightly later than another device. This can prevent too much inrush current that might blow a fuse or trip a breaker in an electrical circuit. 

OFF Delay Relays

OFF delay relays are similar to ON delay relays, however, the delay occurs when the coil is de-energized. When the coil is energized, the contacts instantly close. When the coil is de-energized, there is a delay before the contacts open. A common use for OFF delay relays is when using motors with fans. When the motor is turned off, an OFF delay relay allows the fan to continue cooling the motor for a given period of time before turning off.
