This PoE+ switch features up to 8 PSE (Power Sourcing Equipment) ports with plug-and-play capability, providing power to all connected Powered Devices (PD) immediately upon connection. The fiber ports offer noise-free gigabit Ethernet transmission, enabling fast and reliable long-distance connections to other switches or control centers.The RJ45 console port allows outbound network troubleshooting in case of network issues. The USB port is used for saving configuration files, system log files, and firmware upgrades, reducing network downtime and operational costs. The switch provides various built-in traffic optimization and network performance features to prioritize industrial applications, prevent data loss during communication, and ensure stable transmission. It also includes a topology map compatible with third-party devices for network monitoring. The device complies with cybersecurity standards, protecting the network from vulnerabilities and safeguarding assets.Constructed with industrial-grade components and housed in a high thermal conductivity IP30 aluminum case, it protects the device from tools and hazards. The wide input voltage range (24V–57V) allows operation in many substation applications without additional power outlets. For reliability, redundant power and alarm relay contacts on the terminal block ensure continuous operation and alert in case of power failure. Designed to withstand vibration, shock, drop, and temperature range of -40°C to 75°C (-40°F to 167°F), it is suitable for harsh environments.FunctionsRedundant Power System: Supports simultaneous power supply from two different sources such as SDR-480P-48 power supply or IRA-120/IRA-160 DIN-rail AC-DC power adapters, with power failure alarm.Innovative Power Boost Technology: Uses DC-DC converter to boost DC power from 24V to 57V for high-output PoE/PoE+ devices.High Power Budget for PoE Devices: Supplies up to 30W (IEEE 802.3af/at) to PoE+ devices.SpecificationsStandards: IEEE 802.3 (10BASE-T), IEEE 802.3u (100BASE-TX), IEEE 802.3ab (1000BASE-T), IEEE 802.3z (1000BASE-SX/LX), IEEE 802.3 (Nway Auto-negotiation), IEEE 802.3x (Flow Control), IEEE 802.3ad (Link Aggregation), IEEE 802.3af (Power over Ethernet), IEEE 802.3at (Power over Ethernet Plus), IEEE 802.3az (Energy Efficient Ethernet), IEEE 802.1AB (LLDP), IEEE 802.1ad (QinQ), IEEE 802.1D (STP), IEEE 802.1w (RSTP), IEEE 802.1s (MSTP), IEEE 802.1p (Class of Service), IEEE 802.1Q (VLAN Tagging), IEEE 802.1X (Port Authentication), IEEE 1588v2 (PTP)Interface: 8 x 10/100/1000BASE-T (PoE RJ45), 4 x GbE SFP Slots, 1 x RJ45 Console Port, 1 x USB Port, DIP Switch (Primary/Redundant Power Voltage Drop Alarm setting), LED Panel (PWR, RPS, ALM, POST, SFP, PoE, 1000, LNK/ACT)Power: Input Voltage: Primary/Redundant inputs: 24~57V DC; Connection: Terminal Block; Power Consumption: System: 18W, PoE Power Budget: 240W @ 48V or 124W @ 24V; Alarm Relay: One relay output, 1A @ 24V DCMechanical and Environment: Housing: Aluminum (IP30 Protection); Mounting: DIN-Rail; Operating Temperature: -40°C~75°C (-40°F~167°F); Storage Temperature: -40°C~85°C (-40°F~185°F); Operating/Storage Humidity: 5 to 95% RH (non-condensing); Weight: 955 g (2.1 lb); Dimension (WxHxD): 50 x 161.5 x 119.9 mm (1.97 x 6.35 x 4.72 in)Order InformationModelDescriptionSEN-9648P-24V-SSManaged 8 x 10/100/1000 PoE+ & 4 x GbE SFP Switch, Substation ApprovalKey Features / Technical Specifications:8 x 10/100/1000 PoE+ ports (up to 30W per port)4 x GbE SFP uplink ports1 x RJ45 console port, 1 x USB portWide input voltage: 24V–57V DCPoE power budget: 240W @ 48V or 124W @ 24VOperating temperature: -40°C to 75°CIP30 aluminum housingDIN-rail mountingRedundant power system and alarm relayCompliant with IEEE 1613, IEC 61850-3
