XVME-2121  数字输入模块 具有专业可编程扫描器电路

型号：XVME-2121

XVME-2121数字输入模块提供32数字输入通道。 该模块具有专业可编程扫描器电路，可以检测a在32个输入通道中的任何一个上改变状态。 的

XVME-2121消除了主机进程或不断轮询数字I/O以获取信号的需要转换数据。 在中断转换时，模块可以通过生成VMEbus中断。

这个模块非常适合与按钮或继电器触点。 它包含输入脱线电路与八个跳线可选剥离间隔，和隔离板上12v供应。 还提供了300 VDC的光学隔离和50 VDC反向偏压保护。 它将接受输入电压从10-50 VDC。 XVME-212/2消除了板载DC/DC转换器并提供ttl级输入信号。

Model: XVME-2121

XVME-2121 The XVME-2121 digital input module provides 32 digital input channels. The module has a professional  programmable scanner circuit that can detect A changing state on any of the 32 input channels. the

XVME-2121 eliminates the need for the host process  or to constantly poll digital I/O for signal conversion data. During interrupt transitions, modules can generate VMEbus interrupts.

This module is ideal for making contact with buttons or relays. It contains an input off-line circuit with eight jumper selectable stripping intervals, and a 12v supply on the isolation board. Optical isolation of 300 VDC and reverse bias protection of 50 VDC are also provided. It will accept input voltages from 10-50 VDC. The XVME-212/2 eliminates the onboard DC/DC converter and provides a TTL-level input signal.
