789-621 WAGO Terminal Blocks

Wago 789-621 is a DC digital current sensing transducer designed for a supply voltage range of 12-34Vdc and does not operate on AC supply voltage. It features 2 x RJ45 connectors for connectivity and is specified for an ambient air temperature for operation ranging from -20°C to +70°C, with a storage temperature tolerance from -40°C to +85°C. The transducer supports a communication protocol of Modbus RTU over RS-485, ensuring compatibility with various industrial networks. It is designed for mounting on a DIN-35 rail, with dimensions of H90mm x W35mm x D55mm. The part offers a single analog input (0-140A) with a maximum continuous operating voltage of 15-bits and a control circuit rated current accuracy within 0.5% transmission error. It operates efficiently with a supply current of 8mA at 24Vdc under nominal load conditions. The Wago 789-621 is built to withstand climatic conditions, featuring a mechanical resistance suitable for industrial environments and a response time tailored for rapid signal processing. Its compact size of 35mm in net width and a weight of 0.05kg make it an adaptable solution for various applications requiring precise DC current sensing.
