Current Sensors Procurement Notes

Verify the specific ordering suffix to confirm the selected primary current range (10A, 20A, or 50A) matches the application requirements. Ensure the 24 Vdc supply voltage aligns with existing system infrastructure. Confirm that the 19mm bore diameter accommodates the target conductor size without interference. Check for any additional mounting hardware requirements specified in the official datasheet.

Current Sensors Selection Notes

Select this model when precise AC current monitoring is required in industrial environments. The selectable sensitivity allows flexibility for varying load conditions. The solid core construction simplifies installation compared to split-core alternatives. Consider the 4-20 mA output compatibility with existing PLC or data acquisition systems before finalizing the component choice.
