Dandong Huatong PDM-801A-DS-A-5A Single-Phase Ammeter

I. [Product Introduction]

● Integrates real-time display, comprehensive parameter setting, and network communication;
● Network communication function: Features an optically isolated RS-485 communication port, standard ModBus RTU communication protocol, with each RS-485 communication link capable of connecting up to 128 devices within 1.2 kilometers;
● Easy display operation: PDM-801A/F is equipped with an LCD digital display, allowing various instrument parameter settings via buttons. All settings are stored in the non-volatile memory inside the instrument, ensuring no loss during power failure. All settings are password-protected. Additionally, corresponding system parameter setting software can be used for parameter configuration via its RS-485 communication interface;
● Convenient and flexible installation: No need for power transducers; all modules can be installed locally in a decentralized manner or centrally grouped into panels;
● High reliability: PDM-801A/F adopts multiple hardware and software measures to resist high-frequency interference, ensuring reliable operation in strong magnetic field environments.
