Analog to Digital Signal Converters

November 15, 2012

NK Technologies’ ADC Series Analog to Digital Signal Converters readily accepts analog signals from up to eight loop or separately powered current, voltage, temperature or any other parameter sensor, and seamlessly converts them to a digital signal output that interfaces with the industry standard Modbus RTU digital protocol using a single network address. NK Technologies’ ADC Series Analog to Digital Signal Converters readily accepts analog signals from up to eight loop or separately powered current, voltage, temperature or any other parameter sensor, and seamlessly converts them to a digital signal output that interfaces with the industry standard Modbus RTU digital protocol using a single network address. DIN rail mounting speeds installation. Sensor loop power supplied by the converter can eliminate the needs for a separate DC power supply. The ADC series can be factory-set for 120 or 240 VAC power supplies. The ADC series is ideal for photovoltaic power production due to its ability to measure output current accurately using an appropriately sized sensor, and its ability to measure voltage output from any sensor with a 4-20 mA output. In machine control applications the ADC series combines several analog signals into a single Modbus address, providing users with web-based access to data. The ADC series can also significantly enhance SCADA systems by enabling existing sensor data to be reported and recorded via network communication.
