VMIC VMIVME-3122

Description

VMIC’s VMIVME-3122 is a high-performance 16-bit analog-to-digital converter board.Here is a detailed introduction to the product:

I.Product Overview

The VMIVME-3122 is a member of VMIC’s extensive VMEbus analog input/output product family.It features 16-bit digitizing resolution,program-controlled gain,selectable conversion rate,and automatic scanning of 64 differential or single-ended analog inputs.The board can be directly connected to VMIC’s signal conditioning board series to digitize the outputs of thermocouples,thermal resistors,and strain gauges.

II.Main Features

High Resolution:

The VMIVME-3122 has 16-bit digitizing resolution,providing excellent dynamic range and analog input channel density.

Multi-channel automatic scanning:

Supports automatic scanning of 64 differential or single-ended analog inputs,simplifying the data acquisition process.

Program-controlled gain:

The gain of each channel can be programmed individually or set to a fixed gain common to all channels through software.Channel gain can be selected as x1 or x10 through software.

Selectable conversion rate:

Provides a variety of scan rate options,including 381Hz to 100kHz(high performance option)and 381Hz to 50kHz(standard performance option)to meet different application requirements.

Multiple operation modes:

Supports multiple operation modes such as automatic scanning,data burst and external synchronization,which improves the flexibility and adaptability of the system.

Dual-port data memory:

Equipped with a 16 to 1024-word dual-port data buffer,the digital values​​are stored in the dual-port data buffer and can be accessed from the VME bus at any time,which improves data transmission efficiency.

Onboard timer:

The timed data pulse train is controlled by an interval timer,which can provide a repetitive or single pulse train interval of up to 687 seconds,facilitating the realization of timed data acquisition.

Programmable bus interrupter:

The bus interrupter for mid-scan or end-scan indication simplifies the monitoring of data in the dual-port data buffer.
