Product details

Overview

The REL22502 is a Schneider MiCOM P225 motor protection relay rated for 250 V DC supply, carrying 11 inputs and 6 discrete plus 2 analog outputs, with Modbus RTU, IEC 60870-5-103, and DNP3 protocol support. Schneider discontinued this relay on 2023-12-31; remaining units are sourced through surplus and broker channels, not current distribution.

Comparison with REL22504

The REL22502 and REL22504 share identical I/O, protection functions, and physical dimensions, but differ in protocol order: REL22502 lists Modbus RTU IEC 60870-5-103 DNP3, while REL22504 lists IEC 60870-5-103 Modbus RTU DNP3. Choose REL22502 when the BOM specifies Modbus RTU as the primary protocol.
