Review RDL Solid State Audio Relay

The RDL STSSR1-RST-04 Solid State Relay is a high-performance, solid-state alternative to traditional electromechanical relays. This particular model is designed specifically for use in audio applications, making it an ideal choice for those seeking reliable and precise control over their audio systems.

The STSSR1-RST-04 is a 2-form-A, 1-form-B, normally open (NO) relay, meaning it has two control inputs (Form A and Form B) and two normally open output contacts. The relay can handle a maximum voltage of 28V DC and a maximum current of 1.5A, making it suitable for a wide range of audio applications.

This solid-state relay features a high contact bounce rate of less than 1 microsecond, ensuring fast and reliable switching. It also offers low contact resistance, which minimizes the voltage drop across the contacts, resulting in improved signal quality and reduced distortion.

The RDL STSSR1-RST-04 is designed for long-term reliability, with a lifecycle rating of over 100 million operations. It is also immune to electromagnetic interference (EMI) and radio-frequency interference (RFI), making it a great choice for use in complex audio environments where interference could be an issue.

The relay is housed in a compact, 1.25 x 1.25 x 0.5 inch (32 x 32 x 12.7mm) package, making it an ideal solution for space-constrained applications. It also features a screw terminal design for easy and secure wiring, as well as a status indicator LED to indicate the relay's operational status.

Overall, the RDL STSSR1-RST-04 Solid State Relay is a high-performance, reliable, and versatile solution for audio applications that require precise and fast switching. Its fast contact bounce rate, low contact resistance, and long lifecycle make it a favorite among audio professionals and hobbyists alike.

The RDL STSSR1-RST-04 Solid State Relay is a commonly used device in audio applications for controlling high current loads. Here are some pros and cons that might help you in deciding whether to purchase this relay.

1. Solid State Technology: This relay uses solid state technology instead of traditional mechanical relays. Solid state relays have several advantages over mechanical relays, such as faster switching times, longer life, and lower power consumption.

2. High Current Capability: The RDL STSSR1-RST-04 can handle up to 4 amperes of continuous current, making it suitable for controlling high current loads in audio applications.

3. Opto-Isolation: The relay provides opto-isolation between the control circuit and the load, which helps to prevent electrical interference and noise.

4. Compact Size: The relay is relatively small and compact, making it easy to install in various applications.

5. Low Power Consumption: The relay consumes very little power when it is not switching, which can help to reduce power consumption in your audio system.

1. Cost: Solid state relays generally cost more than traditional mechanical relays, and the RDL STSSR1-RST-04 is no exception.

2. Limited Switching Frequency: Although the relay has fast switching times, it may not be suitable for applications that require very high switching frequencies.

3. Complex Wiring: The relay requires a separate power supply for the opto-isolator, which can make the wiring more complex than with a mechanical relay.

In conclusion, the RDL STSSR1-RST-04 Solid State Relay offers several advantages for audio applications, including fast switching times, long life, and high current capability. However, it also has some disadvantages, such as a higher cost and more complex wiring. Ultimately, the decision to purchase this relay will depend on the specific requirements of your audio application and your budget. If you need to control high current loads in a quiet and reliable way, and are willing to pay a premium for the benefits of solid state technology, then the RDL STSSR1-RST-04 may be a good choice for you. If cost is a major factor, or if you do not require the advanced features of a solid state relay, then a traditional mechanical relay may be a more cost-effective option.

Details:

Radio Design Labs' ST-SSR1 is part of a group products in the STICK-ON series from Labs. When is again allowed to go HI, then turned off and switched the output. The durable bottom adhesive permits quick, permanent mounting nearly anywhere, or use it with RDS racking accessories. In the absence of a control input, feeds module output.

The ST-SSR1 has two line level audio inputs and a single output. When terminal is pulled to ground, switched the output and off. The module contains no mechanical relay. The control circuits utilize solid state switching to apply either of these signals a balanced line driver.

The audio inputs are applied to a low-noise pre amplifier. The ST-SSR1 has user-delectable switching rates. The ST-SSR1 offers the ultimate in totally solid state audio switching, with big PLUS. The module can be used in muting applications where audio must switched off extremely fast.
