NK Technologies introduces ADC Series 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 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 240VAC power supplies.

CTC Series Signal Converters allow you to use an existing standard 5A secondary or low-voltage ProteCT™ current transformer over a conductor to produce an industry standard 4-20mA two-wire, loop-powered signal. The signal is proportional to the current in the primary circuit. The CTC series snaps onto a standard DIN rail. The output is connected to the load and a 24 VDC source and the current transformer is connected.
