Product features
HUS-IDM-G24 Series — 24-Port Unmanaged Industrial Ethernet Switch
Optional IEEE 802.3 af/at/bt Power Over Ethernet support
Three models covering the full PoE spectrum: no PoE (G242S), PoE+ at 30W/port (G242P), and PoE++ at 90W/port (G242Pp9). PoE models power cameras, APs, and sensors over the same Ethernet cable.
Non-blocking store-and-forward at full wire-speed
52 Gbps switch fabric. Frames checked for errors before forwarding — corrupted frames dropped at the switch, not propagated to connected devices.
Auto-negotiation: 10/100/1000 Mbps on all RJ45 ports
All 24 copper ports auto-negotiate speed and duplex. Backward compatible with legacy 10Mbps and 100Mbps devices alongside Gigabit equipment.
Surge protection: ±6kV DC, ±4kV / ±6kV RJ45 (PoE models)
Power port surge protection to ±6kV. RJ45 surge protection to ±4kV on non-PoE model and ±6kV on PoE/PoE++ models. IEC 61000-4-5 compliant.
Dual redundant DC power with Fault Alarm relay
6-pin terminal block: Pin1/2 PWR1, Pin3/4 PWR2, Pin5/6 Fault Alarm output. Two independent power feeds with automatic failover. Fault Alarm relay connects to monitoring systems without requiring SNMP.
DIN-Rail and wall-mount installation
Standard 35mm DIN-rail or wall-mount. Fits directly inside industrial control cabinets and HEPDA IP66-rated enclosures without adapters.
-40°C to +75°C industrial operating temperature range
Full industrial hardened temperature range. Handles cold outdoor enclosures and elevated ambient temperatures inside sealed control cabinets in tropical climates.
IP40 aluminium enclosure, fanless passive cooling
No fans, no moving parts to fail. Passive cooling through the aluminium chassis.
IEEE 802.3x flow control (Full Duplex) & backpressure (Half Duplex)
Prevents frame loss under high-traffic load. Full Duplex and Half Duplex supported on all ports.
MAC address auto-learning and auto-aging
8K MAC address table with automatic learning and aging.
NDAA Compliant
Compliant with NDAA Section 889 — a procurement requirement for US government, defence-adjacent, and public infrastructure projects.
IEEE 802.1Q VLAN Transparency
Passes 802.1Q VLAN-tagged frames transparently without stripping tags — compatible with VLAN-aware managed switches upstream.

Applications
Where it is deployed
Outdoor CCTV Surveillance — Large Scale
The HUS-IDM-G24 Series was designed specifically for outdoor CCTV surveillance. 24 PoE+ or PoE++ ports connect cameras directly from a single switch — no separate power injectors, no additional power cabling runs. The 588W PoE budget covers 24 high-resolution cameras with heaters and IR illuminators simultaneously.
Factory Automation and Smart Manufacturing
24-port density provides enough connections for a large production-floor network node — PLCs, HMIs, vision systems, barcode readers, and SCADA outstations all on one switch. 52 Gbps non-blocking fabric ensures full Gigabit throughput across every port under simultaneous load.
Transportation and Smart City Infrastructure
MRT stations, bus interchanges, and road tunnel monitoring. 24 ports feed cameras, passenger information displays, access control readers, and environmental sensors — all PoE-powered from a single DIN-rail mounted switch. NDAA compliance meets government procurement requirements.
Outdoor Wi-Fi and Wireless Infrastructure Deployments
High-performance outdoor Wi-Fi 6 access points require more than 30W. The HUS-IDM-G242Pp9's PoE++ capability at 90W per port handles dual-radio APs, active antennas, and multi-radio mesh nodes — eliminating separate power infrastructure for each AP.
Oil, Gas, and Petrochemical Facilities
Redundant DC power with Fault Alarm relay output, ±6kV surge protection on both DC and RJ45 ports, and -40°C to +75°C operating range are the minimum specifications for field equipment in refineries, LNG terminals, and chemical processing facilities.
Building Management and Commercial Facilities
Large commercial buildings run IP cameras, access control, intercoms, BMS sensors, and digital signage — all PoE-powered on copper. A single 24-port PoE switch per floor covers all devices with SFP fibre uplinks to the building backbone.
