The ADC series of 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.
“With finger-safe field wiring terminals clearly marked for field installation, quick DIN rail mounting and an ability to connect up to eight 4 to 20 mA analog sensors to produce a digital signal representing 0 to 100% of each sensor output, the ADC makes it easier than ever to convert analog signals to an industry-standard Modbus output,” says NK Technologies President Philip Gregory,.
The ADC series is well suited for photovoltaic power production because it can measure output current accurately using an appropriately sized sensor, and an ability to measure voltage output from any sensor with a 4 to 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 reporting and recording sensor data by network communication.
