Overview

ANet-2E8S1 is a high-performance industrial communication gateway developed by Acrel. Based on an embedded Linux platform, it collects and consolidates data from power meters, protection devices and other field equipment through eight isolated RS485 channels, then forwards the data to local or remote management systems through two Ethernet ports. It supports protocol conversion, data forwarding, remote control and edge computing for power monitoring, energy management and substation automation applications.

· Wide-range AC/DC 85–265 V power input with reverse-connection protection.
· Two 10/100 Mbps adaptive Ethernet ports for uplink communication.
· Eight optically isolated RS485 channels for downstream device access.
· Up to 32 devices per RS485 channel and up to 256 field devices in total.
· Local and remote configuration, real-time monitoring and multi-data-center forwarding.
· Breakpoint resume, XML data transmission and AES data encryption.
· One RS232 management port, one USB 2.0 port and one standard SD card slot.
· Protocol conversion and edge-computing functions for heterogeneous field devices.

Characters

· Industrial ARM Cortex-A7 processor delivers reliable gateway performance.
· Key EMC immunity tests reach Level 4 requirements.
· Power and communication terminals pass a 2 kV withstand-voltage test.
· Reusable custom template libraries simplify repeated project configuration.
· One-click generation of meter information points improves commissioning efficiency.
· Selectable or complete single-device datasets support flexible data forwarding.
· Batch operations and step-filling tools accelerate large-scale device configuration.
· ANetOS protection and recovery functions improve long-term operating reliability.
