1. DI/DO/RS485 Integration for Industrial I/O and Serial Device Connectivity

Native DI/DO/RS485 interface via removable 8-pin terminal block, eliminating the need for an external serial gateway

1-channel digital input (12V–30V) and 1-channel digital output (normally open/closed/pulse, 2A@30VDC) enable direct alarm triggering, relay control, and event-driven automation

RS485 serial server supports Modbus RTU transparent transmission over TCP/IP, seamlessly connecting legacy PLCs, RTUs, meters, and field sensors to modern IP networks

Dedicated RS485 LED indicator provides real-time TX/RX status visibility for instant serial link diagnostics

2. Dual 1G/2.5G SFP Uplinks for Cost-Effective Fiber Aggregation

Two multi-rate SFP slots support 1GBase-X and 2.5GBase-X, providing flexible fiber uplink options for medium-distance or EMI-sensitive environments where copper is unsuitable

Dual-rate flexibility allows the same hardware to adapt to both existing 1G fiber infrastructure and emerging 2.5G backbone upgrades without device replacement

SFP DDM (Digital Diagnostic Monitoring) enables real-time optical transceiver health monitoring for proactive maintenance in unmanned field deployments

G.8032 ERPS ring protection across SFP uplinks delivers ≤20ms automatic failover, ensuring continuous operation in redundant fiber ring topologies

3. 8-Port PoE+ with Intelligent Power Management and Full L2+ Feature Set

All 8 RJ45 ports support IEEE 802.3af/at PoE+, delivering up to 30W per port with a 240W total power budget for cameras, APs, VoIP phones, and industrial sensors

Per-port PoE priority, power scheduling, PD watchdog, and alarm threshold configuration ensure reliable power delivery and remote PD fault recovery without on-site intervention

Comprehensive L2+ management: VLAN/QinQ, IGMP v1/v2/v3, ACL, 8-queue QoS (SP/WRR), 802.1X, DHCP server/relay, SNMP v2c/v3, MQTT, sFlow, plus IPv4/IPv6 static routing

Hardened industrial design with IP40 fanless housing, Din-rail mounting, -40°C to +75°C operating range, 6KV surge protection, and redundant 44–57VDC power input

Application:

IP surveillance networks, industrial automation edge nodes, smart transportation cabinets, oil & gas remote sites, utility substations, and any deployment requiring serial legacy device integration with fiber uplink redundancy in a compact DIN-rail form factor.
