NK Technologies has introduced the ADC series of analog-to-digital signal converters. The ADC series readily accepts analog signals from up to eight-loop or separately powered current, voltage, temperature or any other parameter sensor and 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, the company notes, and sensor-loop power supplied by the converter can eliminate the need for a separate DC power supply. The ADC series can be factory-set for 120 V AC or 240 V AC power supplies.
According to the company, the ADC series is ideal for photovoltaic power production because of 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 mA to 20 mA output.
