Vibro-Meter GSI124 244-124-000-022 Galvanic Separation Unit

Description

The Vibro-Meter GSI124 244-124-000-022 is a galvanic separation unit designed for use with Vibro-Meter machinery monitoring systems. It provides power for 2-wire transducers and signal conditioners, including piezoelectric transducers with integrated electronics, signal conditioners, and proximity probe signal conditioners. The unit provides galvanic isolation between the transducer and monitoring system, supports long-distance AC signal transmission, reduces the effects of ground noise, and eliminates the need for Zener barriers in intrinsically safe applications. Its compact, DIN-rail mountable design makes it suitable for reliable continuous operation in industrial environments.

Frequently asked questions

Q:What is the Vibro-Meter GSI124 244-124-000-022?
A:The Vibro-Meter GSI124 244-124-000-022 is a galvanic separation unit designed for machinery monitoring systems. It supplies power to compatible 2-wire transducers and signal conditioners while providing galvanic isolation for reliable signal transmission.

Q:What types of devices can the GSI124 be used with?
A:The GSI124 is designed for use with piezoelectric transducers with integrated electronics (such as the CE series), piezoelectric transducer signal conditioners (IPC series), and proximity probe signal conditioners (IQS 4xx series). It can also power other electronic devices with a current consumption of less than 20 mA.

Q:Does the GSI124 help reduce electrical interference?
A:Yes. The unit rejects a significant portion of ground noise, minimizes the effects of ground potential differences, and reduces AC noise pickup between the sensor and the monitoring system.

Application areas

The Vibro-Meter GSI124 244-124-000-022 is a highly versatile galvanic separation unit designed to serve as a high-frequency interface and safety barrier within machinery protection systems. 

• Hydroelectric Generator Deflection: Handling low-frequency to high-frequency AC dynamic outputs from displacement sensors tracking hydro-turbine main shaft runout and alignment.
• High-Noise Industrial Plant Fans: Rejects massive amounts of RMS ground noise and eliminates potential AC noise pickup between the metallic sensor case and sensor poles, making it perfect for long cable runs found in large steel mills or mining ventilation systems.
• Refinery Air Blowers & Crackers: Isolating high-frequency vibration signals on key refinery assets while blocking dangerous ground loops or fault voltages from reaching the central monitoring room.
