LX731 - Analog/Digital I/O Interface

LX731 - Analog/Digital I/O Interface

The LX731 provides automation control interfaces for both analog and digital devices. A common requirement for many production QA/QC applications require both control and sensing of various remote device functions.

The analog interfaces and be configured as either one input and one output, or two inputs, or two outputs. Likewise the digital interfaces can be configured as either single input and single output, or two inputs, or two outputs. Each digital interface provides 24 bits of data, over 16 million codes.

The analog interfaces can be used to read sensors such as temperature, pressure, speed, voltage, current, etc. They can also be used to drive linear actuators, chart recorders, variable speed controls, and other linear devices.

The digital interfaces can be used to drive relays, stepper motors, positioning, LEDs, indicators, robotics, etc. They can also be used to read status conditions, test results, etc.

Automated Digital Calibration

The LX731 does not contain any analog trim pots. Instead all calibrations and trimming are performed by automated computer controlled routines in a GPIB test system, with adjustments provided by digital trim DACs or digital constants. All calibrations are stored within the non-volatile flash memory of each module, and peformed with traceable equipment and standards. Accuracy is measured to better than 0.01dB or 0.1%, as applicable to each parameter. A calibration chart is included with each module to document the actual performance, parameters, and calibration results.
