The Hirschmann MSP30-28-3A, configurator code MSP30-24040SCY9MRHHE3A, is a modular Gigabit Ethernet industrial DIN rail switch from the MSP30 family running HiOS Layer 3 Advanced software, designed for automation engineers and network planners who need dynamic Layer 3 routing integrated with industrial switching and redundancy in a compact fanless DIN rail device. Manufactured by Hirschmann, a Belden brand, the MSP30-28-3A provides 24 Fast Ethernet ports and four Gigabit Ethernet uplinks, operating between 0 °C and +60 °C at just 18 W from a 24 V DC supply. The Layer 3 routing engine supports OSPFv2, RIPv1/v2, ECMP, static unicast routing, wire-speed full routing across VLAN-based and port-based interfaces, Proxy ARP, and ICMP Router Discovery. VRRP with HiVRRP enhancements and tracking delivers gateway redundancy, while multicast routing covers DVMRP, PIM-DM, PIM-SM/SSM, and IGMP proxy across v1/v2/v3. Switching functionality includes IGMP Snooping and Querier per VLAN, DiffServ classification and policing, QoS to 802.1D/p, Jumbo Frames, Voice VLAN, and storm protection. Redundancy is provided by HIPER-Ring over link aggregation, MRP per IEC 62439-2 as client and manager, RSTP, MSTP, LACP, Sub Ring Manager, and redundant network coupling. Security features include 802.1X, RADIUS, TACACS+, DHCP Snooping, Dynamic ARP Inspection, IP Source Guard, and LDAP. Industrial profiles cover PROFINET, EtherNet/IP, Modbus TCP, and IEC 61850, and PTPv2 Boundary and Transparent Clocks support precise time synchronisation. Certified to CE, FCC, cUL508, and NEMA TS2, the MSP30-28-3A is well suited to process automation, power distribution, water treatment, and factory networks requiring integrated routing.
