• Input Voltage: 24VDC (stable power supply, supporting redundant power input for high reliability, rated power consumption ≤15W)

• Protection Functions: Overvoltage, overcurrent, overheating, short-circuit protection, and built-in fault self-diagnosis function; additional pump-specific protection including no flow/deadhead protection, loss of prime (LOP)/well dry run protection, broken pipe protection and impeller anti-jam protection[1]

• Mounting: 35mm DIN rail installation (complying with IEC 60715)

2. Brief Product Overview

• High Reliability: Adopts industrial-grade components and integrated design, supports redundant power input, with mature protection mechanisms and fault self-diagnosis function, ensuring stable operation in harsh industrial environments and strong resistance to overload and interference; passes EMC test to resist industrial electromagnetic interference, fully-closed module design enhances dust and moisture resistance[2].

• Comprehensive Protection & Self-diagnosis: Built-in overvoltage, overcurrent, overheating and short-circuit protection, and fault self-diagnosis function, which can quickly respond to abnormalities and avoid module and load damage; supports communication loss detection to ensure system stability, records fault codes for convenient troubleshooting, and integrates pump-specific protection functions including no flow/deadhead protection, loss of prime (LOP)/well dry run protection, broken pipe protection and impeller anti-jam protection[1].

4. Simplified Installation Instructions

118. Check wiring correctness and tightness, ensure no loose connections or short circuits; ensure the module is reliably grounded, with a grounding resistance ≤4Ω to prevent electric shock or electromagnetic interference.

4.3 Key Notes

• Ensure correct wiring polarity and communication line connection, reverse polarity or wrong communication wiring may damage the module or affect communication; the module must be reliably grounded, with a grounding resistance ≤4Ω to prevent electric shock or electromagnetic interference.

• The module adopts standardized and modular design, which is compatible with Yaskawa automation systems (especially NX100 series and Sigma series), and can be directly replaced and used on site; ensure the new module model is P0151JS and consistent with the original one during replacement.
