Function

64 differential or single-ended inputs

Starts in auto-scan mode – no software initialization required

Continuously digitizes input channels and stores results in dedicated channel dual-port registers (auto-scan mode)

Jumper-selectable scan from 2 to 64 channels

Supports real-time and off-line built-in testing

Five operating and test modes

-Auto Scan Mode (Gain = 1)

– Random polling mode

-Random interrupt mode

-Scan polling mode

-Scan interrupt mode

VME bus interrupts can be programmed to interrupt at the completion of a single A/D conversion or at the completion of a 2- to 64-channel sweep

User programmable interval timer supports periodic scanning of all channels

Jumper programmable gains of 1. 10. 100. 200. and 500

Selectable A/D ranges of 0 to +10V, +5V and +10V

Low and high inputs: +10my to +10V

Selectable low-pass filter (VMlVME-3113A for better high-frequency rejection)

Overvoltage protection input

5 x 1060 input impedance

33 kHz conversion rate

Selectable output codes: binary, offset binary, binary with sign extension

Applications

-Factory automation and instrumentation – Process control

-Laboratory instrumentation

-Machine monitoring

– Data acquisition
