GE VMIVME-3122-210 16-bit Analog-to-Digital Converter Board

Product Overview

The VMIVME-3122-210 is a member of the VMIC (which may refer to a brand or division of GE) VMEbus analogue input/output product family. It is a high-resolution, 16-bit, 64-channel analogue scanning and digitising input board for VMEbus system applications.

Key Features

High resolution: with 16-bit digitisation resolution, it can accurately convert analogue signals to digital signals.

Multi-channel inputs: Provides 64 differential or single-ended analogue input channels with excellent dynamic range and analogue input channel density.

Programmable Gain: Supports programmable channel gain, channel gain can be selected as x1 or x10 through software, which improves measurement flexibility and accuracy.

Multiple Operation Modes: Supports multiple operation modes such as auto scan, data burst and external synchronisation to meet different application requirements.

High-speed conversion rate: Provides optional conversion rate up to 100kHz (high-performance option) to meet the needs of high-speed data acquisition.

Dual-port data memory: Equipped with dual-port data memory for convenient data storage and access.

On-board timer: with on-board timer for controlling timed data bursts, simplifying the process of data acquisition.

Programmable Bus Interrupter: Provides a programmable bus interrupter for mid-scan or end-scan indication, simplifying the monitoring of data in the dual-port data buffer.

Application Areas

System applications where the VMIVME-3122-210 can benefit from its features include factory automation, process control, data acquisition systems, training simulators, and laboratory instrumentation.

Technical Specifications 

A/D converter range: ±2.5V, ±5V, ±10V, 0 to +5V, 0 to +10V (selectable via jumpers).

Data buffer size: 16 to 1024 word dual-port data buffer.

Channel block size: Adjustable to 1, 8, 16, 32 or 64 channels.

Scan Rate: 381Hz to 100kHz (high performance option), 381Hz to 50kHz (standard performance option).

Other Features

Digitising the output of thermocouples, RTDs and strain gages can be done by connecting directly to VMIC's family of signal conditioning circuit boards.

Multiple boards can be synchronised together, enabling up to 16 boards to initiate each scan simultaneously.

Interval timers, bus interrupters, channel counters, and mid-scan/end-of-scan flags simplify monitoring of data in the dual-port data buffer.
