The difference is the protocol priority in the firmware; both support the same three protocols, so they are functionally interchangeable for Modbus RTU and DNP3 networks. The REL22503 is discontinued. Sourcing is via surplus and broker channels; an RFQ confirms available quantity and lead time.","metaTitle":"Schneider REL22503 MiCOM P225 motor protection relay, discontinued","metaDescription":"Schneider REL22503 MiCOM P225 motor protection relay, 250 V DC, 11 digital inputs, 6 discrete + 2 analog outputs, Modbus RTU/IEC 60870-5-103/DNP3, discontinued.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["General Purpose Relays"],"specifications":{"Depth":"Total : 270 mm Embedded : 240 mm","Width":"103 mm","Height":"Total: 177 mm Embedded: 157.5 mm","Display type":"Backlit LCD: 2 lines of 16 characters","Device mounting":"Flush","Protection type":"ANSI 50G/51G : earth fault ANSI 37 : phase undercurrent ANSI 14 : underspeed (2 set points) ANSI 66 : starts per hour ANSI 49RMS : thermal overload protection ANSI 27 : undervoltage ANSI 59 : overvoltage Locked rotor ANSI 46 : negative sequence overcurrent ANSI 50/51 : overcurrent ANSI 50BF : breaker failure","lifecycle_stage":"current","Number of inputs":"11 0 4 1.3","Range of product":"MiCOM P225","Device short name":"P225","Number of outputs":"6 discrete 2 analog","Relay application":"Motor protection","Discrete input voltage":"24...250 V DC 19.2 V standard variant 48...250 V AC 19.2 V standard variant 48...250 V DC 105 V further option 48...250 V DC 77 V further option 48...250 V DC 154 V further option 48...240 V AC 105 V further option 48...240 V AC 77 V further option 48...240 V AC 154 V further option","Switchgear diagnosis type":"VT supervision ANSI code: VTS CT supervision ANSI code: CTS Trip circuit supervision ANSI code: TCS","[Us] rated supply voltage":"24...250 V DC 19.2...300 V 48...250 V DC 38.4...300 V 48...240 V AC 38.4...264 V","Communication port support":"RS485 RS232","Communication port protocol":"Modbus RTU IEC 60870-5-103 DNP3","Control and monitoring type":"Circuit breaker/contactor control","Network and machine diagnosis type":"Fault recording Event recording Disturbance recording15 s"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3,752.02","priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/902f954d8597e663a140b36c28c9a047.pdf","sourceUrl":"https://www.se.com/vn/en/product/REL22503/p225-over-under-voltage-modbus-+-6-rtds-monitoring/","alternativesUrl":"https://aoctrl.com/api/mcp/products/REL22503/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/schneider/REL22503","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/schneider/REL22503 when reusing this data.
