Wago's Feedthrough Current Sensors continuously measure DC currents

Wago’s Feedthrough Current Sensors are designed to continuously measure DC currents. Via serial connection, the 789-620 (0–80A DC) and 789-621 (0–140A DC) sensors transmit data with an accuracy of 0.5% (full scale value).

Equipped with dual RJ-45 interfaces, the sensors transmit data via RS-485 serial communication lines up to 4000 feet. Thirty-two current sensors can reside on one line for connection to the Wago-I/O-System or PC as a modbus slave. Both models are addressable via on-unit DIP switch and feature an operational status LED. The sensors operate in temperatures of -20° C to +70° C.
