Description
The EHG9512 Series is a highly reliable Gigabit Managed Ethernet Switch. Its IEC61850-3 compliance allows it to be core part in the IEC 61850 network in power substations and control centers. The series is also certified by DNL.GL (former KEMA) to meet the IEC61850 applications and to support the transmission of GOOSE messages used for fast communication between IEDs.
The IEEE1588 Precision Time Protocol capabilities allow the deployment of EHG9512 Series in networks with stringent time Synchronization requirements. It can act as hw-assisted transparent clock providing nanosecond-accurate correction-field packet-update and as a sw-assisted boundary clock, achieving a µs-level accuracy.
The device equips 8 x 10/100/1000BASE-T(X) RJ-45 ports and 4 x 1000 BASE-X SFP ports. With its high performance, it provides network redundancy self-recovery mechanisms is less than 20ms on full load that enables the user to build a reliable network through a redundant ring topology. ERPS/STP/MSTP/RSTP/MRP (Client) and many other compatible rings are supported. With a Multifunctional web dashboard, its offers intelligent features such as Quality of service (QoS), Virtual LAN (VLAN), IGMP, IGMP Snooping, Port mirroring and security. To prevent network intrusions, it is necessary to have a good accessing control mechanism that can identify, authenticate and authorize users. EHG9512 support user account, password policy, and authentication interface managements functions that comply with IEC62443 standard.
The EHG9512 Series is designed to be used in core power utilities. It provides dual redundant power inputs with Reverse Polarity Protection and two sets of relay that allow the user build up a stand-alone fault alarm system. Its wide operating temperature of -40 to 85°C and DIN-Rail mounting capacities make it suitable to be used in remote substations where harsh environment and reliability is an issue.

Specifications taken from the manufacturer datasheet.
Which version do I need?
Three EHG9512 part numbers differ only by power input: EHG9512-4SFP (1P1EHG95120001G, DC), EHG9512-4SFP-AC (1P1EHG95120003G, 100-240 VAC) and EHG9512-4SFP-HV (1P1EHG95120002G, 110-370 VDC high voltage). All three carry 4 × 1000FX SFP and 8 × 1000TX RJ45. The datasheet notes that all series are UL 61010-2-201 certified except the HV series.
Typical applications for the EHG9512
- IEC 61850 substation automation networks
- Power utility control centres
- GOOSE messaging between IEDs
- Fibre-rich substation ring backbones (4 SFP uplinks)
- Remote unmanned substations in harsh environments

EHG9512 — frequently asked questions
What is the difference between the EHG9512 and the EHG9508?
Port count. The EHG9512-4SFP has 8 × 1000TX RJ45 copper ports and 4 × 1000FX SFP fibre slots (12 ports); the EHG9508-2SFP has 6 × 1000TX RJ45 and 2 × 1000FX SFP (8 ports). All other published specifications in the shared datasheet are the same.
Is the EHG9512 approved for power substation use?
Yes. It is IEC 61850-3 certified including the 6.10.3 seismic test and meets IEEE 1613. The datasheet states the series is certified by DNV.GL (former KEMA) to meet IEC 61850 applications and to support GOOSE messages used for fast communication between IEDs.
How fast does the ring recover after a link failure?
The datasheet specifies network redundancy self-recovery in less than 20 ms on full load, quoted as < 20 ms across 40 switches for ERPS and Compatible Ring. STP, RSTP, MSTP, MRP, Compatible Ring/Chain and U-Ring are also supported.
Which power input should I order?
There are three: DC (rated 24-57 VDC, input range 19.2-62.7 VDC), AC (100-240 VAC rated, 85-264 VAC input) and HV (110-370 VDC). Each is a separate part number. Only the HV version is excluded from the UL 61010-2-201 certification.
Does the EHG9512 do precision time protocol in hardware?
Partly. The datasheet states it acts as a hardware-assisted End-to-End transparent clock providing nanosecond-accurate correction-field packet update, and as a software-assisted boundary clock. IEEE 1588 PTP V1 and V2 are supported, alongside NTP Server/Client and SNTP.
