WAGO DIN-Rail DC Current Sensors
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). This can be used to quickly identify defective or damaged PV modules, bolstering performance and reliability. 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. The 789 Series feedthrough configuration eliminates the need to terminate conductors, simplifying commissioning. Both models are addressable via on-unit DIP switch and feature an operational status LED. Engineered for harsh environments, the sensors operate in temperatures of -20°C to +70°C.
