It features a standard coil voltage of 12 volts DC, with a maximum working current of 30 amperes and a maximum working voltage of 250 volts AC or 30 volts DC. This relay is suitable for both AC and DC circuits.

The contact rating for the 1174663 relay is 10A at 250V AC or 30V DC. It operates quietly due to its low contact resistance and comes with a replaceable silver-plated contacts that ensure reliability and longevity. This relay also features a form C PCB mounting design, ensuring easy installation on printed circuit boards.

The contact normal voltage drop of this relay is 15 millivolts, and the coil resistance is 340 ohms. It has a contact bounce time of 30ms, which ensures smooth and accurate switching action. The operating temperature range for the 1174663 relay is from -25 C to 60 C. It comes with a clear plastic case that protects against dust and moisture.

This SPST relay comes with a coil to prevent magnetization, ensuring that it does not remain in the on position after the power source is removed. The terminals of the relay are labeled for ease of identification and wiring. It is essential to ensure that the relay is handled properly and installed correctly to minimize the risk of damage and ensure proper functionality.

Overall, the 1174663 SPST relay is a high-quality, robust, and reliable component suitable for various electrical applications that require remote control or automation of electrical loads. Its compact size, broad compatibility with voltage and current specifications, and quiet operation make it an excellent choice for a wide range of applications.

The SPST (Single Pole Single Throw) relay with model number 1174663 is a commonly used electromechanical switching device. In this response, I will provide you with pros and cons to help you make an informed decision about purchasing this relay.

1. Reliable: SPST relays like the model 1174663 are known for their reliability. They have a simple construction which makes them less prone to failure compared to complex relays.

2. Cost-Effective: SPST relays are generally economical as they have fewer moving contacts and require fewer coil voltages and energies.

3. Easy to use: SPST relays can be controlled with a single input, simplifying their implementation in various applications. Often used in overcurrent protection, interlocking systems, and signaling circuits.

4. Easy to repair: In case of any malfunctions or issues, SPST relays can be repaired with minimal effort due to their simple design.

1. Limited switching capacity: As SPST relays can only switch between one pole or position, they might not be suitable for more complex applications requiring multiple pole switching.

2. Slower response time: SPST relays use mechanical contacts that may cause longer response times compared to solid-state switches or relays with faster switching technologies.

3. More susceptible to noise: Due to their mechanical construction, electromechanical switches like the SPST relay are more susceptible to noise, which might affect their performance.

4. Contact bounce: With continual switching, an issue called contact bounce might occur, producing intermittent or incorrect switching for brief periods.

In conclusion, the 1174663 SPST relay is an economical and reliable solution for applications requiring basic switching functionality with a simple interface. Although it comes with limitations like limited switching capacity, slower response time, and susceptibility to noise, its reliability and ease of use may outweigh these drawbacks for certain applications.

If the specifications and performance requirements of your project align with the features offered by the SPST relay, we recommend this component for your application. However, if you require more complex switching, faster response time, or noise reduction, it might be more suitable to invest in alternatives like solid-state relays or more advanced electromechanical relays.
