Time Delay Relays
Time Delay Relays are electrical relays that are designed to delay the opening or closing of contacts. ESDR125A5P is a type of time delay relay. This relay offers customers good quality, ease of use, and versatility.
ESDR125A5P Application Fields
ESDR125A5P are used for a wide range of applications, such as in industrial, railway, marine, and mobile environments. The broad application field of these relays makes them a popular choice for a variety of applications.
Industrial applications are a primary use for the ESDR125A5P, with applications such as providing control for pumps, blowers, stop and start motors, and fan control. These devices are also used in train and bus CO2 detectors for safety, in Hazardous area category 4 surge and ESD protection, as well as in other heavy-duty machinery.
The mobile environment provides a wide range of novel uses for these time delay relays. These include applications in vehicles, including alarm systems and automobile HVAC systems, as well as on boats and ships. Marine applications include engine control, vent and bilge pump control, and Deck Equipment.
ESDR125A5P Working Principle
ESDR125A5P is a single-output bistable relay and hence has a couple of important characteristics. This relay has an external trip coil and two sets of contacts. When the external trip coil is energized, it causes the mechanism to move into the reset (make) position, causing the contacts to close. When power is removed from the external trip coil, the mechanism moves to the latch (break) position and the contacts open.
The ESDR125A5P also has a delay timer which is adjustable and can be set to delay the reset (make) and/or latch (break) position of the contacts. This allows for time delays in milliseconds up to several minutes. The delay timer is adjustable via a resistor/capacitor (RC) circuit connected to the reset and latch coils.
Conclusion
ESDR125A5P are extremely versatile time delay relays which can be used in a wide range of applications, from industrial to mobile. These relays have adjustable delay timers which can be set to delay the make and break of contacts. This makes them ideal for applications which require an adjustable time delay.
