Advantages of choosing an isolated capture card
Galvanic isolation separates the sensor signal from the low-voltage backplane of the measurement system that may be exposed to dangerous voltages. Isolation offers a number of advantages, including: Protects expensive equipment, user lives, and data from transient voltages Improved immunity Removal of ground loops Improved Common-Mode Voltage RejectionThe isolated measurement system provides a ground plane for the analog front end and system backplane, separating the sensor measurements from the rest of the system. The ground connection of the isolation front end is a floating pin that can operate at a different electric potential than the ground. Any common-mode voltages that exist between the sensor ground and the measurement system ground are suppressed. This prevents the formation of ground loops and rejects any noise on the sensor lines.
Isolation technology is recommended for measurement systems that involve any of the following:
Immediate proximity to dangerous voltages.
Industrial environments where transient voltages may be present.
Environments where there are fluctuating common-mode voltages or ground potentials.
Electrically noisy environments, such as those where industrial motors are present.
Transient voltage sensitive applications such as common mode voltage, transient high voltage, and electrical noise must be prevented from transmitting through the measurement system, and the more common applications are industrial control, process control, and automotive testing. Measuring devices with isolation provide reliable measurements in these harsh environments. For medical devices that come into direct contact with a patient, isolation helps prevent transient current transmission from the power lines through the device.
