Schneider Electric MCSESR043F23F0 Modicon 4-Port Redundancy Switch DIN Rail Industrial Ethernet Switch

The Schneider Electric MCSESR043F23F0 is a Modicon Networking redundancy switch with 4 copper 10/100BASE-TX ports, built for RSTP, MRP and PRP redundant-network links. It runs Ethernet TCP/IP with SNMP, HTTPS and VLAN-based access control, accepts a 12...48 V DC or 24 V AC supply, and draws 7 W on a 35 mm DIN rail mount.

Applications

The MCSESR043F23F0's shielded RJ45 connectors suit medium-complexity, isolated network segments carrying medium traffic loads — a motor control center or process-area ring rather than a full plant backbone. PRP fits process-control or SCADA links where a failed path must hand over with no detectable interruption, a tighter guarantee than the ring-recovery time of RSTP or MRP on the standard Modicon Networking managed switches.

Selection Notes

The MCSESR043F23F0 is Modicon's dedicated Redundancy Switch, supporting PRP (Parallel Redundancy Protocol) alongside RSTP and MRP — pick it over a standard managed switch when the application needs PRP's zero-recovery-time dual-network redundancy rather than the ring-recovery time of RSTP or MRP. Its dual supply rating (12...48 V DC or 24 V AC) suits installations where the standard switches' 12...24 V DC-only input does not match the available control voltage.
