NK Technologies ADC Series Signal Converter connects up to eight 4-20 mA loop-powered analog sensors, or up to eight separately powered 4-20 mA output sensors, or up to four of each. This will produce a digital signal representing 0-100% of each sensor output. It is the perfect solution for photovoltaic power production system monitoring. The ADC converter allows for individually-ranged devices to interface with the industry-standard Modbus RTU serial protocol. The device can accept analog signals from current, voltage or temperature sensors, allowing the installer great versatility and higher accuracy. It was designed and built to meet NK Technologies’ trusted standards of reliability and ease of use.
