129478-01 | BENTLY NEVADA High Voltage DC Input Module

Description

The 129478-01 is a BENTLY NEVADA High Voltage DC Input Module, a core component of the 3500 series machinery protection system. Designed for condition monitoring of rotating machinery and high-voltage equipment, it supports monitoring of parameters including vibration, displacement, and temperature in industrial settings. Its primary function is signal conversion, translating 0-1000V DC high-voltage signals into standard low-voltage output signals of 0-10V DC or 4-20mA, enabling seamless data collection and processing by downstream systems. The module features robust redundancy capabilities: it supports FCI redundant installation with automatic active-standby switching, and is compatible with triple module redundancy (TMR) architectures to ensure uninterrupted system operation. For connectivity, it integrates the EGD (Ethernet Global Data) protocol, is compatible with controllers like GE Mark VIe, and supports RS-232/RS-422 serial communication as well as industrial standard protocols including Modbus TCP/IP and Profibus. Built for harsh environments, it includes built-in overvoltage/overcurrent protection, electrical isolation of no less than 2500V DC, and an IP65 protection rating to withstand demanding industrial conditions. It also features a user-friendly design for easy installation and maintenance, aligning with the plug-and-play component design of the 3500 series.
