The Hirschmann RED25-04002T1TT-SDDY9HPE2S is a managed DIN rail industrial Fast Ethernet switch delivering four 10/100 Mbit/s copper RJ45 ports in a fanless 47 x 131 x 111 mm enclosure, designed for cost-effective entry into high-availability industrial network architectures requiring advanced redundancy protocols. Running HiOS Layer 2 firmware, the switch supports a comprehensive redundancy stack including Parallel Redundancy Protocol (PRP) per IEC 62439-3, High Availability Seamless Redundancy Protocol (HSR), Fast MRP and standard MRP per IEC 62439-2, Device Level Ring (DLR), RSTP per IEEE 802.1D-2004, and LACP link aggregation, providing seamless failover and zero-downtime networking suited to process automation and energy infrastructure. VLAN management including 802.1Q, IGMP snooping per VLAN, QoS port prioritisation per 802.1D/p, TOS/DSCP, and Voice VLAN ensure traffic engineering capability matching industrial networking requirements. Industrial protocol support covers PROFINET IO, EtherNet/IP, Modbus TCP, and IEC 61850 MMS server and switch model, making the switch directly interoperable with leading PLC, DCS, and substation automation platforms. Security features include 802.1X port-based access control, RADIUS authentication, MAC-based port security, denial-of-service prevention, HTTPS certificate management, and configurable password policies. Time synchronisation via PTPv2 transparent and boundary clock modes ensures precision timing for process-critical applications. Power input accepts 12-48 VDC or 24 VAC with redundant supply support, and the IP20 DIN rail housing withstands 35 V/m electromagnetic immunity and IEC 60068 shock and vibration. Certified to CE, FCC, EN61131, and UL 61010-2-210 with an MTBF of over 6.4 million hours. Available from Recab, your Nordic partner for Hirschmann industrial switch solutions.
