ADC Signal Converters convert sensor output to Modbus format.

Press Release Summary:

ADC Signal Converters convert sensor output to Modbus format.

Nov 15, 2012 - Accepting analog signals from up to 8 loop or separately powered sensors, ADC Series seamlessly converts signals to digital output that interfaces with Modbus RTU digital protocol using single network address. Sensor loop power supplied by converters can eliminate need for separate DC power supply. Featuring finger-safe field wiring terminals and DIN rail mounting, converters are suited for PV power production, machine control applications, and SCADA systems.

Quickly and Easily Convert Any Standard Sensor Output to Modbus Format with New ADC Signal Converters from NK Technologies

Press release date: Nov 14, 2012

SAN JOSE, CA – 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 240 VAC power supplies.

“With finger-safe field wiring terminals that are clearly marked for field installation, quick DIN rail mounting and the ability to connect up to eight 4-20 mA analog sensors to produce a digital signal representing 0-100% of each sensor output, the ADC makes it easier than ever to convert analog signals to an industry-standard Modbus output,” says Philip Gregory, President, NK Technologies.

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.
