GSI127 244-127-000-017 Galvanic Separation Unit In Stock

Product Details:

Description:

The GSI127 is a galvanic isolating device from the VM product line. It is designed to be used with signal conditioners, charge amplifiers and electronics (connected or integrated) for various measurement chains and/or sensors from the same brand.

The GSI127 galvanic separation unit is a versatile unit that can is used for the transmission of highfrequency AC signals over long distances in measurement chains using current-signal transmission or as a safety barrier unit in measurement chains using voltage-signal transmission. More generally, it may be used to supply any electronic system (sensor side) having a consumption of up to 22 mA.

The GSI127 also rejects a large amount of the frame voltage that can introduce noise into a measurement chain. (Frame voltage is the ground noise and AC noise pickup that can occur between the sensor case (sensor ground) and the monitoring system (electronic ground)). In addition, its redesigned internal power supply results in a floating output signal, eliminating the need for an additional external power supply such as an APF19x. The GSI127 is certified to be installed in an Ex Zone 2 (nA) when supplying measurement chains installed in Ex environments up to Zone 0 ([ia]). The unit also eliminates the need for additional external Zener barriers in intrinsic safety (Ex i) applications. The GSI127 housing features removable screwterminal connectors that can unplugged from the main body of the housing to simplify installation and mounting. It also features a DIN-rail mounting adaptor that allows it to be mounted directly on a DIN rail.

(For standard versions of the GSI127, the housing is completely grey in colour. For Ex approved versions of the GSI127, the housing is grey in colour but with a screw-terminal connector (top) for sensor-side signals (electrical connections) that is blue in colour)
