INS-8648M is a high-performance 8-port 10/100/1000 RJ45 downlink and 4-port GbE SFP uplink managed industrial switch designed for communication between controllers and devices in automation settings. The SFP port offers long-distance, noise-free fiber transmissions that adapt to Fast and Gigabit Ethernet speeds. It is used with industrial devices 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, designed to save configuration files, save system log files, and upgrade firmware, reduces network downtime and operational costs. The switch offers various in-built traffic optimization and network performance features to prioritize important data packets, prevent the loss of data during communication, and stabilize transmission. It is compatible with third-party devices, which can be easily identified with the help of the Topology map. This device complies with cybersecurity standards to safeguard the network from vulnerabilities and protect your assets.

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. This device is Certified DNV GL approved for safe use in marine applications. 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. networks into smaller parts and separate broadcast domains.

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.

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

Redundant Ring for Fast Network Recovery
Xpress Ring for detection and recovery of link failure in milliseconds.
