1.Core Functions

The MOXA 8-port industrial switch connects multiple automation devices within the same local area network, forwards Ethernet data frames, and ensures stable real-time communication under industrial interference.www.plcva.com

1. Ethernet data packet forwarding (Store-and-Forward) Receive data frames from connected devices, learn MAC addresses, forward packets to target port, isolate unnecessary broadcast traffic. Support auto-negotiation, auto MDI/MDIX, full/half duplex adaptation.
2. Industrial protocol transparent transmission Support standard industrial Ethernet protocols: PROFINET, EtherNet/IP, Modbus TCP. It enables communication between PLC, HMI, servo controllers, sensors and I/O modules.
3. Anti-interference & network protection Built-in broadcast storm protection to avoid network collapse caused by broadcast flooding. QoS function prioritizes critical control data over non-urgent background data.
4. Redundant power input Most models adopt dual DC power supply (12/24/48 VDC). If one power source fails, the other takes over automatically to avoid network outage. Relay alarm output triggers signal for power loss or port disconnection.
5. Network redundancy (Managed models only) Support Turbo Ring, Turbo Chain, RSTP/STP/MRP. Network recovery time less than 20ms, ideal for high-reliability control systems.
6. Network management (Managed/Smart models only) Web GUI configuration, VLAN, port mirroring, SNMP, LLDP, IGMP Snooping, access control, event log and email alarm notification.
7. Wide-temperature & rugged hardware design Metal casing with IP30 / IP40 protection. Wide operating temperature range: standard -10~+60℃, wide-temperature (-T) version -40~+75℃, strong EMC anti-electromagnetic interference capability.
8. Installation & status indication DIN-rail mounting for control cabinet installation. LED indicators show power, link status, data activity and fault status.

2. Applications & Purpose

Core Purpose

It serves as the network hub for industrial automation systems. It establishes stable local Ethernet connections for field control equipment, transmits real-time control signals, process data and fault alarms, and guarantees reliable communication in harsh industrial environments with vibration, dust and electromagnetic noise.www.plcva.com

Typical Application Fields

• Factory automation: production lines, machine tools, packaging machinery, robotic systems
• Power industry: substation automation, generator auxiliary control
• Oil & gas, petrochemical: field remote I/O and monitoring network
• Intelligent transportation: tunnel, railway, highway monitoring system
• Water treatment & HVAC: pump and fan control network
• Marine, mining and other harsh-site monitoring systems

Working Flow

PLC / HMI / servo / sensor → Ethernet cable → MOXA 8-port switch → data frame forwarding → exchange real-time control and monitoring data between field devices; managed models support redundant ring network to prevent single-point network failure.plcva.com

3. Key Characteristics

• Port: 8 × RJ45 10/100Mbps or 10/100/1000Mbps Gigabit ports; partial models have optional fiber SFP slots for long-distance transmission
• Mounting: DIN rail, wall mounting optional
• Power: Dual redundant DC power input, reverse polarity protection
• Enclosure: Metal housing, IP30/IP40, dust-proof
• Certification: CE, FCC, UL, compatible with industrial automation standards

Important distinction: Unmanaged switch is plug-and-play for simple network expansion; managed switch supports ring redundancy, VLAN and network monitoring, used for critical control backbone network.
