VIBRO-METER 244-127-000-017-A2-B02 | Meggitt GSI127 Galvanic Separation Unit

VIBRO - METER 244 - 127 - 000 - 017 - A2 - B02 is a specific model of Meggitt's GSI127 current isolation unit. The following is an introduction to it:

Functional use: It is a power supply and current isolation unit for sensors and/or signal conditioners, suitable for devices with current or voltage output. It can provide 4kV rms current isolation between the sensor end and the monitoring end, and 50V rms current isolation between the power supply and the output signal, which can effectively prevent electrical interference between different circuits and ensure the stability and accuracy of signal transmission.

Signal transmission and compatibility: It has a transfer function of μA to mV for long-distance signal transmission; it also has a transfer function of V to V for short-distance signal transmission. At the same time, it is compatible with industry-standard IEPE sensors and 4-20mA loop-powered sensors, such as CE620, CE630 and PV660 vibration sensors, as well as CE687 and PV685 vibration sensors, etc., and has a wide range of applications.

Application scenarios: It can be used in a variety of measurement systems, including CA vibration, CP dynamic pressure, TQ proximity, VE speed measurement, etc. It can be used for long-distance high-frequency AC signal transmission in measurement chains using current signal transmission, and can also be used as a safety isolation unit in measurement chains using voltage signal transmission. In addition, it can suppress a large amount of frame voltage that may introduce noise into the measurement chain. The isolation unit is certified for use in potentially explosive environments and/or safety-related applications, and complies with the SIL2 standard of IEC 61508, with high safety and reliability.

Technical parameters: Input signal range (sensor end) is 0 - 20.75mA or 0 - 20.3V (DC), output signal range (monitoring end) is 0.8 - 20.8V (DC). Transfer function (sensitivity) is available in 0.5V/mA, 1V/mA, 3.2V/mA, 1V/V or -1V/V ± 1%, output offset voltage is available in 0, 7, 8 or 10Vdc ± 0.2Vdc. Frequency range is DC to 20000Hz, linearity is less than 0.2%, operating temperature range is -20℃ to 70℃.
