Schneider RXM4LB2BD Power Relay<\/h1>\n
<\/div>\n

1. Product Overview<\/h2>\n
<\/div>\n
The Schneider Electric RXM4LB2BD is a 14-pin miniature plug-in electromechanical power relay<\/strong> belonging to the Harmony Zelio Relay RXM series. Configured with 4 changeover contacts (4CO, 4NO + 4NC)<\/strong> and a 24 V DC coil<\/strong> with an integrated LED status indicator, it is engineered for low-to-medium power control applications requiring multiple circuit switching.<\/div>\n
<\/div>\n
Rated at 3 A per contact<\/strong> for resistive loads (AC-1\/DC-1) up to 250 V AC \/ 28 V DC, this relay serves as a critical interface between low-power control signals (e.g., from PLCs or sensors) and higher-power industrial loads. It features a compact, DIN-rail mountable design (via compatible sockets) and complies with IEC 61810-1, UL 508, and CSA C22.2 No. 14 standards, making it ideal for industrial automation panels, machinery control, signal distribution, and building management systems.<\/div>\n

Function<\/th>\nDetailed Description<\/th>\n<\/tr>\n<\/thead>\n
Multi-Circuit Switching<\/td>\n4 independent changeover contacts (4NO + 4NC) enable simultaneous control of up to 4 separate load circuits with a single control signal, maximizing I\/O efficiency.<\/td>\n<\/tr>\n
Signal Isolation & Amplification<\/td>\nProvides galvanic isolation between the 24 V DC control side and the load side, protecting sensitive controllers from voltage transients while amplifying signals to drive actuators.<\/td>\n<\/tr>\n
Visual Status Indication<\/td>\nA built-in LED illuminates when the coil is energized, offering instant visual confirmation of the relay\u2019s operating state for rapid troubleshooting.<\/td>\n<\/tr>\n
Plug-and-Play Maintenance<\/td>\nStandard 14-pin plug-in design allows tool-free replacement and hot-swapping on compatible sockets, minimizing equipment downtime during servicing.<\/td>\n<\/tr>\n
Wide Load Compatibility<\/td>\nCapable of switching resistive, inductive, and small capacitive loads up to 3 A, suitable for solenoids, small motors, lighting, and indicator circuits.<\/td>\n<\/tr>\n
Mechanical Test Capability<\/td>\nCompatible with sockets featuring a test button, enabling manual verification of contact operation without energizing the coil.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
