Product Description

Signal Isolators are utilized in a variety of settings, including industrial, medical, and other locations where electrical separation is required for safety. They can also be used to amplify signals, enable the addition of instruments to an overburdened loop, or scale down harmful, high-voltage signals to safer levels. Our Signal isolators are very effective and safe to use. Each channel in a multi-channel device operates separately and is segregated from the others to prevent channel contact. Share, split, boost, protect, and digitize process signals are all common uses for these devices.

Some of the common features of signal isolators include:

1. Galvanic Isolation: Signal isolators provide galvanic isolation, which means they electrically separate the input and output circuits. There is no direct electrical connection between the two sides, preventing the flow of current and eliminating ground loop problems.

2. Noise and Interference Rejection: Signal isolators can reject common-mode noise and electromagnetic interference (EMI) that could otherwise affect the accuracy and performance of the signal being transmitted.

3. Voltage Transient Protection: Signal isolators can protect sensitive equipment from voltage spikes and transients that may occur on one side of the circuit, preventing them from propagating to the other side.

4. Signal Amplification or Attenuation: Some signal isolators offer the ability to amplify or attenuate the signal strength. This feature allows adjusting the signal level to match the requirements of the receiving equipment.

5. Wide Input and Output Range: Signal isolators can handle a wide range of input and output signals, supporting various types of analog and digital signals.

6. High Isolation Voltage: Signal isolators are designed to withstand high voltage differences between input and output circuits, ensuring reliable and safe isolation.

7. Low Signal Distortion: Signal isolators maintain the integrity of the signal being transmitted, minimizing distortion and preserving the accuracy of the original signal.

8. Fast Response Time: Signal isolators provide fast response times to ensure timely transmission of signals in dynamic applications.

9. Compact and DIN Rail Mountable: Signal isolators are often compact in size, suitable for space-constrained installations, and can be mounted on DIN rails for easy integration into control panels.

10. Analog and Digital Compatibility: Signal isolators can work with both analog and digital signals, making them versatile for different types of systems.

11. Intrinsically Safe Design: Some signal isolators are intrinsically safe, meaning they are designed to prevent the release of electrical energy that could cause sparks or explosions in hazardous environments.

12. Isolation Status Indication: Some isolators feature LEDs or indicators to show the status of the isolation, helping with troubleshooting and system maintenance.

13. High Reliability and Industrial-grade Construction: Signal isolators are often built to withstand harsh industrial environments, offering high reliability and longevity.


Q: What is a signal isolator, and how does it work?

A: A signal isolator is an electronic device used to electrically separate two parts of a circuit while allowing the transmission of signals between them. It typically utilizes galvanic isolation, which means there is no direct electrical connection between the input and output circuits. Instead, it uses components like transformers, optocouplers, or capacitors to transfer the signal without allowing the flow of current. This helps protect sensitive equipment from noise, voltage spikes, and ground loop issues.

Q: Why is signal isolation important in electronic systems?

A: Signal isolation is crucial in electronic systems for several reasons:

  • Safety: It prevents the risk of electric shocks and protects operators and sensitive equipment.
  • Noise and Interference Rejection: It helps eliminate common-mode noise and electromagnetic interference, ensuring signal integrity and accuracy.
  • Ground Loop Elimination: Signal isolators prevent ground loop issues that can cause unwanted voltage differences and distort signals.
  • Voltage Transient Protection: It shields equipment from voltage spikes and transients that could damage components.
  • Signal Integrity: By isolating signals, the integrity of the transmitted signals remains intact.

Q: What types of signals can signal isolators handle?

A: Signal isolators can handle various types of signals, including analog signals such as voltage and current, as well as digital signals like RS-232, RS-485, CAN, and others. They are designed to work with a wide range of input and output signal types.

Q: How do I choose the right signal isolator for my application?

A: When selecting a signal isolator, consider the following factors:

  • Signal Type: Ensure the isolator is compatible with the specific type of signal (analog or digital) you are working with.
  • Isolation Rating: Check the isolator's isolation voltage and ensure it can handle the voltage difference between the input and output circuits.
  • Input and Output Range: Make sure the isolator supports the voltage or current range required for your application.
  • Response Time: For dynamic applications, choose an isolator with a fast response time.
  • Environmental Conditions: Consider the operating temperature range, humidity, and any potential exposure to hazardous elements if used in extreme conditions.
  • Mounting and Form Factor: Choose an isolator that is suitable for your installation method, whether it's DIN rail mounting, panel mounting, etc.

Q: Can signal isolators amplify signals?

A: Some signal isolators come with the capability to amplify or attenuate signals. This feature allows adjusting the signal strength to match the requirements of the receiving equipment or compensate for signal losses.

Q: How are signal isolators powered?

A: Signal isolators are typically powered from an external power source. They may require a separate power supply to operate, especially in applications where the isolated circuits have different power sources.

Q: Are signal isolators suitable for hazardous environments?

A: Yes, some signal isolators are designed to be intrinsically safe, making them suitable for use in hazardous environments where the risk of sparks or explosions needs to be minimized.

Q: Can I cascade multiple signal isolators in series?

A: It is generally not recommended to cascade multiple signal isolators in series. Each isolator introduces some signal distortion and delays, and cascading them could compound these effects, leading to decreased signal quality. If higher isolation is needed, it's better to use a single isolator with a higher isolation rating.

Q: What are the maintenance requirements for signal isolators?

A: Signal isolators typically have no moving parts and require minimal maintenance. Regular visual inspections for any signs of damage or wear are recommended. In harsh environments, cleaning to remove dust and debris may be necessary. However, proper installation and adherence to manufacturer guidelines will ensure their reliable operation over time.

Q: Can I use a signal isolator in both AC and DC circuits?

A: Yes, signal isolators are generally suitable for both AC and DC circuits. However, it's essential to choose the appropriate type of isolator based on the type of signal (analog or digital) and the voltage or current requirements of your specific application.
