Schneider Electric Easergy MiCOM P849 IEC 61850 Digital Input & Output Extension Device
Schneider Electric Easergy MiCOM P849 is an IEC 61850 Digital Input and Output Extension Device designed to expand the digital I/O capacity of existing Easergy MiCOM protection relays and substation automation systems. It provides a simple and reliable way to add additional digital inputs and outputs without replacing the existing protection equipment.
Built on the proven Easergy MiCOM Px40 hardware platform, the MiCOM P849 collects digital signals from protection relays and transmits circuit breaker open and close commands through secure IEC 61850 communication. Its flexible design allows it to function as an I/O extension unit or as a compact remote terminal unit (RTU) for a wide range of utility and industrial applications.
The MiCOM P849 supports modern digital substations with redundant Ethernet communication, advanced cybersecurity and seamless integration into SCADA systems. It offers a cost-effective solution for expanding automation capabilities while reducing engineering effort and maintenance costs.
