Schneider Electric RXM4LB2B7 Harmony RXM 3 A 4 C/O 24 V AC LED Miniature Plug-in Relay

The Schneider Electric RXM4LB2B7 is a Harmony RXM series miniature plug-in relay with 4 C/O contacts rated 3 A, controlled by a 24 V AC coil. It includes a status LED that lights when the relay is energized, switches up to 750 VA AC or 84 W DC per its maximum switching capacity, and uses flat faston-type pins for direct plug-in mounting on an RXZE socket.

Selection Notes

The status LED that RXM4LB1B7 lacks is standard here, giving a visual on/off indication for the relay coil without opening the panel or probing terminals - useful in cabinets where the plug-in relay bank is not otherwise instrumented. Four C/O contacts switch four independent circuits from one 24 V AC coil, one step up from the 2 C/O RXM2L relays in the same range. At 3 A per contact it is derated versus the 2 C/O family's 5 A rating, the trade-off for the extra contact block.

Applications

Used to fan out a single PLC or control signal to multiple independent field circuits with visual state confirmation at the relay - status relays, multi-zone interlocking, or distributing one command to several contactor coils - on an RXZE plug-in socket.
