The Hirschmann MSP30-20-3A, configurator code MSP30-16040SCY9MRHHE3A, is a modular Gigabit Ethernet industrial DIN rail switch from the MSP30 family running HiOS Layer 3 Advanced software, designed for industrial network architects and automation engineers who need integrated Layer 3 dynamic routing combined with strong switching and redundancy on a small-port-count DIN rail platform. Manufactured by Hirschmann, a Belden brand, the MSP30-20-3A provides 16 Fast Ethernet ports and four Gigabit Ethernet uplinks, operating from 0 °C to +60 °C at just 17 W from a 24 V DC supply in a compact 314 x 148 x 142 mm fanless chassis. The Layer 3 routing engine supports OSPFv2, RIPv1/v2, static unicast routing with ECMP, full wire-speed routing across VLAN-based and port-based router interfaces, Proxy ARP, ICMP Router Discovery, and IP/UDP Helper. VRRP with HiVRRP enhancements and tracking ensures gateway redundancy, while multicast routing covers DVMRP, PIM-DM, PIM-SM/SSM, and IGMP proxy. Switching capabilities include IGMP Snooping per VLAN v1/v2/v3, 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 support PROFINET, EtherNet/IP, Modbus TCP, and IEC 61850, and PTPv2 Boundary and Transparent Clocks are included. Certified CE, FCC, cUL508, and NEMA TS2, the MSP30-20-3A is well suited to process automation, power infrastructure, and transport networks requiring Layer 3 routing on a compact platform.
