该单元是通用电气发那科自动化VMIC系列数字转换器、输入输出单元和其他电路板的一部分。该单元特别被列为VMIVME-2170A，一种数字输出板型号。这块板装有一套光学耦合器。该模块框架中包括的许多特征是组件，例如32个光学隔离输出、2.5至300毫安的输出以及现场可配置的上拉电阻器。VMIVME-2170A模块需要可从外部施加的上拉电压。

VMIVME-2170A型号采用双Eurocard形状因子PC板，能够提供必要的地址解码和数据传输控制逻辑，能够接受8位和16位数据传输。光学耦合器能够将32个输出以及VMEbus模块彼此隔离。VMIVME-2170A能够支持两种类型的数据传输、监控数据和非特权数据。

VMIVME-2170A配备了几个功能特性。在板功能方面，它以32位处理能力运行，光学隔离，专门为VMEbus设计和优化。VMIVME-2170A具有如此高的隔离率，它还提供了一个灵活、经济高效的4字节数字输出端口，具有高抗噪性。

VMIVME-2170A型号已不再生产，无论是来自其原始开发商通用电气，还是来自其前生产商Abaco Systems。这些型号可从AX Control获得，经过使用，但经过完全翻新和优化，可在当今的工业标准范围内运行。

VMIVME-2170A

This unit is a part of the General Electric Fanuc Automation VMIC series of digital converters, input and output units, and other circuit boards.This unit in particular is listed as the VMIVME-2170A, a model of digital output board. This board is fitted with a set of optical couplings. The many features that are included in the frame of this module are components such as the 32 optically isolated outputs, the outputs that range from 2.5 to up to 300 milliamperes, and the field configurable, pull up resistors. The VMIVME-2170A module requires pull up voltage that can be applied externally.

The VMIVME-2170A model comes implemented with a double Eurocard form factor PC board, which is able to provide the necessary address decoding and data transfer control logic, able to accept both 8 bit and 16 bit data transfers. The optical couplings are able to isolate the 32 outputs from one another, as well as the VMEbus module. The VMIVME-2170A is able to support both types of data transfer, supervisory data and nonprivileged data.

The VMIVME-2170A is outfitted with several functional characteristics. In regards to board function, it operates at 32 bits processing capabilities, optically isolated, and specifically designed and optimized for the VMEbus. The VMIVME-2170A features such high rates of isolation, it also provides a flexible, cost effective, 4 byte digital output port with a high noise immunity.

The VMIVME-2170A model is no longer in production, either from its original developers, General Electric, and from its former producers, Abaco Systems. These models are available from AX Control, used, yet completely refurbished and optimized to run within the set of today’s industrial standards.
