The Northern Design RTU is an extremely cost-effective solution to read meters using Modbus. A DIN-rail meter, three phase, CT connected. It includes 2 isolated pulse outputs, so these are a simple way to interface with other equipment. One can read a wide range of parameters via Modbus. Energy values are kWh, kvarh inductive, kvarh capacitive. Instant values, kW, kVA, kvarh, PF, Hz, Per phase V, A, kW, V per phase, Neutral current, THD for V & I per phase. The meter has a display to view and setup the Modbus address. Then other parameters are setup via Modbus address 1-199 baud 4800, 9600, 19200.
