OverviewINS-8405EM is an unmanaged industrial Gigabit Ethernet switch with five auto-negotiation 10/100/1000 Mbps RJ45 downlink ports. It expands Ethernet networks and connects to diverse devices including managed switches and monitoring systems. The device integrates traffic optimization and network performance controls to prioritize critical industrial packets and maintain stable transmission under demanding conditions.
Product Highlights- 5 x 10/100/1000 RJ45 downlink ports supporting multiple Ethernet speeds
- Auto-negotiation and MDI/MDI-X for plug-and-play operation
- Flow Control and Storm Control to optimize network performance
- Industrial QoS for EtherNet/IP, PROFINET and GOOSE; per-port priority and 802.1p tagging
- Resistance to electromagnetic interference and industrial noise
- DNV Marine Approval for marine applications
- Operating temperature range -40°C to 75°C and IP40 aluminum housing
Features- Ruggedized industrial design — Industrial-grade components, effective thermal conduction and an IP40 aluminum enclosure. Protected against vibration, EMI, ESD, power surge, over-voltage, over-current and reverse polarity. Rated for operation from -40°C to 75°C. Complies with CE, FCC and RoHS standards.
- Quick installation with auto-negotiation — Ready to operate when connected. Single 12–48 VDC power input via 3-pin terminal block. 10/100/1000 Mbps ports support auto MDI/MDI-X. Slim form factor and standard TH35 DIN-rail mounting.
- Traffic control to preserve bandwidth — Flow Control and Storm Control prevent traffic overload, reduce packet loss and maintain device availability.
- VLAN passthrough for transparent forwarding — Forwards VLAN-tagged packets without modification, ensuring operational data integrity across devices.
- Priority for time-sensitive data — 802.1p tagging and per-port priority (port #1 priority) ensure delivery of high-priority industrial traffic during congested conditions.
- Industrial protocol prioritization — iQoS can prioritize EtherNet/IP, PROFINET and GOOSE traffic for deterministic delivery.
- Large network compatibility and monitoring support — LLDP filter reduces device flapping with managed switches, improving monitoring accuracy in expansive networks.
