Astranet's new data acquisition PCB converts a Stellarnet spectrometer into a monitor for on-line and in-line process control, or allows it to perform as a stand-alone instrument without a PC.

Astranet's new data acquisition PCB converts a Stellarnet spectrometer into a reliable, low-cost monitor for on-line and in-line process control, or allows it to perform as a stand-alone instrument without a PC.

Providing a convenient interface between an on-line spectrometer and a programmable logic control (plc) system, the PCB includes an integrated 25MHz, 32-bit microprocessor, 14-bit programmable analogue-to-digital converter (ADC) and 4Mb flash memory.

Flexibility of operation with peripherals is ensured through the device's six digital outputs, six digital inputs, four-off 0-20mA analogue outputs and LCD display driver for stand-alone use.

A spectrometer is also enabled for use with a xenon flash lamp.

Stellarnet users will benefit from the high-speed USB 2.0 interface, RS-232 interface for firmware upgrade, and C++ and LabView APIs.

Astranet says that its data acquisition PCB can be configured to many different types of CCD and photo diode array sensors, allowing it to be used in a wide range of applications.
