INS-8608A is a high-performance 8-port 10/100/1000 RJ45 downlink managed industrial switch designed for communication between controllers and devices in automation settings. It is used with multi-axis robots and their peripherals such as PLCs, HMIs, and legacy devices. It offers auto-negotiation on all its ports and Modbus TCP to aggregate devices easily in industrial Ethernet applications.

The RJ45 type console port allows outbound network troubleshooting when networks go wrong. The USB port supports firmware upgrade, keeps configuration settings safe, and downloads log files to manage network status offline. The switch optimizes traffic with Storm, and Flow Control, and QoS - it prioritizes industrial data packets, prevents the loss of data during communication, and offers a stable transmission. It has a topology map to visualize the network and complies with cybersecurity standards to safeguard the network from vulnerabilities.

This switch is built with industrial-grade components and enclosed in an IP30 aluminum case with high thermal conductivity, which protects the device from tools and hazards. Designed to withstand vibration, shock, free fall, interference, and temperatures ranging from -40℃~75℃ (-40°F~167°F), it suits extreme industrial applications. To ensure reliability the redundant power supply and alarm relay contact on the terminal block ensures non-stop operations and issues alerts if power fails.


Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.

Port-based and IEEE 802.1Q VLAN
GARP (Generic Attribute Registration Protocol) and GVRP (Generic VLAN Registration Protocol) for segmentation of large networks into smaller parts and separate broadcast domains.

Firmware Auto Backup
Auto backup of firmware to the secondary memory and activation of it from there in case of loss of the primary memory.

Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.

Efficient Network Monitoring and Management
SNMP (Simple Network Management Protocol) and RMON (Remote Monitoring) protocols for efficient traffic management and monitoring.

Efficient Traffic Prioritization
Effective QoS mechanisms for priority assignment, transmission of dedicated traffics to specific applications, and allocation of appropriate bandwidth to mission-critical communications.

Redundant Ring for Fast Recovery 
Xpress Ring for rapid detection and recovery of link failure in milliseconds and ERPS (Ethernet Ring protection Switching), Dual Homing, LACP (Link Aggregation Control Protocol), and RSTP (Rapid Spanning Tree Protocol) for continuous and consistent operation.
