NB3000 HMS Networks Industrial Automation Components

Ewon by HMS Networks NB3000 is a Remote Terminal Unit (RTU) designed for DC power monitoring and RTU functions. It features DIN rail mounting and operates within an ambient air temperature range of -30 to +65°C. As part of the Netbiter series, this unit has dimensions of H57mm x W35mm x D88mm and requires a supply voltage of 12Vdc-24Vdc (isolated). It comes with a 2m cable and supports communication via 802.11 (Wi-Fi) and Modbus RS-485. The NB3000 is equipped with two analog inputs: one for voltage measurement (2-wire +/- input) and one for current measurement (from Hall sensor). It offers voltage measurement accuracy of Class 1 (+/-1% of reading; 5 digits) for 1-10Vdc input and Class 1 (+/- 1% of reading; 3 digits) for 10-90Vdc input, with a resolution of 0.1V. Current measurement accuracy is Class 1.5 (+/-1.5% of reading; 5 digits) for -20...-5A, Class 1.5 (+/-1.5% of reading; 6 digits) for -5...+5A, and Class 1.5 (+/-1.5% of reading; 5 digits) for +20...+80A, with a resolution of 0.1A. Power measurement accuracy is Class 3 (+/-3% of reading; 5 digits) for 0...7200W, with a resolution of 1W. Temperature measurement accuracy is +/-0.5°C for -10...+85°C and +/-2°C for -55...+125°C, with a resolution of 0.1°C.
