Product Description

Overview

The Bently Nevada 1034549-40 Dual Galvanic Isolator Module is engineered for hazardous area installations within the 1701 FieldMonitor system. It provides electrical isolation between field-mounted sensors in high-risk environments and the safe-area electronics, ensuring intrinsically safe signal transmission without compromising measurement accuracy.

This module allows standard Proximitor® probes and vibration sensors to safely operate in explosive atmospheres while preserving the integrity of dynamic vibration and static position signals. Its compact form factor integrates directly into the 1701 Terminal Base, reducing installation complexity and footprint compared to conventional DIN-rail barriers.

Key Features

Intrinsically Safe Signal Isolation

• Galvanic isolation physically separates field and safe circuits, preventing high-energy faults or surges from reaching hazardous zones.

• Compliant with ATEX, IECEx, and CSA standards for Class I, Division 1 or Zone 0/1 environments.

Dual-Channel Configuration

• Supports two independent input channels, maintaining full compatibility with dual-channel monitor modules such as 1701/15 and 1701/25.

• Each channel preserves signal fidelity for accurate vibration and shaft position measurements.

High-Fidelity Signal Transmission

• Engineered to minimize attenuation and phase distortion for high-frequency signals, essential for Keyphasor or vibration-based diagnostics.

• Wide bandwidth supports both dynamic vibration and static displacement measurements.

Seamless System Integration

• Directly mounts into 1701 Terminal Base, simplifying wiring and reducing cabinet space.

• Efficient power usage from system backplane while providing field sensor excitation.

Technical Specifications

Applications

• Hazardous area vibration and displacement monitoring for rotating machinery.

• Protection of field-mounted Proximitor probes and accelerometers in Zone 0/1 or Class I Division 1 environments.

• Integration with 1701 FieldMonitor systems, including dual-channel monitors and isolator terminal bases.
