☆型号：VMIVME-4199 16 通道模拟隔离放大器板 完全独立于 VME 控制总线
【产品详情】
特征：
（16） 隔离式模拟电压放大器通道
高隔离度，500 VDC
高势垒阻抗，1,000 MΩ
差分输入
高输出电流，20 mA
内部电源
GE Fanuc / VMIC VMIVME-4199 模拟隔离放大器板是一款 16 通道模拟隔离放大器板，专为 VMEbus 应用而设计。VMIVME-4199 在模拟输入和输出之间提供电流隔离。所有输入均为差分输入。除电源外，该板是独立的，并且完全独立于 VME 控制总线。
每个通道均可通过单个电阻器单独编程，以获得 x1 至 x100 的电压增益。未使用的输入和输出可以断开，以进一步优化整体隔离特性。输入可配置为反相或无相。
VMIVME-4199 板是必须消除接地环路或信号返回之间的电位差超出传统模拟板 20 至 30 V 隔离限值的系统的重要组成部分。

Internal power supply
The GE Fanuc/VMIC VMIVME-4199 Analog Isolation Amplifier board is a 16-channel analog isolation amplifier board designed specifically for VMEbus applications. The VMIVME-4199 provides current isolation between analog input and output. All inputs are differential inputs. Except for the power supply, the board is self-contained and completely independent of the VME control bus.
Each channel can be individually programmed with a single resistor to obtain voltage gains from x1 to x100. Unused inputs and outputs can be disconnected to further optimize the overall isolation characteristics. The input can be configured to invert or no phase.
The VMIVME-4199 board is an important part of systems where the potential difference between the ground loop or signal return must be eliminated beyond the 20 to 30 V isolation limit of conventional analog boards.
