93770-4 低压直流电源输入模块

【产品详情】

GE / Bently Nevada 3500/15 系列电源是半高模块，必须安装在机架左侧专门设计的插槽中。3500 机架可以包含一个或两个电源（交流和/或直流的任意组合），任一电源都可以为整个机架供电。如果已安装，则第二个电源将充当主电源的备用电源。当一个机架中安装两个电源时，下部插槽中的电源充当主电源，上部插槽中的电源充当备用电源。只要安装了第二个电源，卸下或插入任一电源模块都不会中断机架的运行。

3500 电源接受各种输入电压，并将其转换为其他 3500 模块可接受的电压。3500 系列机械保护系统提供三种电源版本，如下所示：1. 交流电源，2. 高压直流电源 3.低压直流电源。

3500 Interface between the monitoring system and System 1 mechanical management software

Combine 3500/20 RIM functionality with a communications processor

Works with M-series displays

The GE/Bentley Nevada 3500/22M Series Transient Data Interface (TDI) is the mechanical management software for the interface between the 3500 monitoring system and the Bentley Nevada System 1. TDI combines the capabilities of 3500/20 rack interface modules with the data collection capabilities of communication processors such as TDXnet.

The TDI runs in a RIM slot in the 3500 rack with M-series monitors (3500/40m, 3500/42m, etc.) to continuously collect steady-state and transient waveform data and pass this data to the host software over an Ethernet link. Static data capture is standard with TDI, but using an optional channel-enabled disk also allows capturing dynamic or transient data. In addition to integrating communications processor capabilities in 3500 racks, the TDI improves on previous communications processors in several ways.

The TDI provides certain functions common to the entire rack. However, the TDI is not part of the critical monitoring path and has no impact on the normal operation of the entire monitoring system. Each rack requires one TDI or RIM. The TDI occupies only one slot in the rack and is always located in the Slo t 1 (next to the power supply).

For triple modular redundancy (TMR) applications, the 3500 system requires the TMR version of TDI. In addition to all standard TDI functions, TMR TDI also performs "monitor channel comparison." 3500 TMR configuration performs monitoring voting using the Settings specified in Monitoring options. In this way, TMR TDI continuously compares the output of three (3) redundant monitors. If TMR detects that the information in one of the monitors is no longer equivalent to the remaining two monitors (within the configured percentage), it flags the monitor as an error and puts the event in the system event list.
