VCL-2724, Parallel Redundancy Protocol (PRP) Switch

VCL Products > Industrial Grade Switch > VCL-2724, Parallel Redundancy Protocol (PRP) Switch

The unit is Failsafe and never itself becomes a point of failure in the electrical ethernet mode. The “protected interface” automatically reverts to and reconnects to the “primary interface” even in a power down condition.

Get Data Sheet

VCL-2724 PRP / HSR Switch is a simple, compact, easy-to-use solution designed to be used in critical Ethernet networks that cannot afford packet loss which may otherwise occur during ring-recovery, or switchover upon failure of either one of the Ethernet LANs. The VCL-2724 is designed to carry critical Ethernet data over two parallel LANs with zero packet loss.

The VCL-2724 PRP / HSR Switch may also be used to carry Ethernet data in over an HSR ring with absolutely no packet loss. VCL-2724 PRP / HSR Switch is the only presently available in the industry which ensures that the PRP / HSR Switch never itself becomes a point of failure, even in power down condition.

Features
Technical Specification

Features:

Ruggedized construction. IEC 61850-3 Compliant. Suitable for industrial applications.
Available in compact DIN Rail and 19-inch Rack Mount with 1+1 power supply options.
Total number of Ethernet Ports: 3

One Interlink Port: Input Ethernet Port (Optical / Electrical - User Selectable).

Network loop detection and removal.
Cut-through and store-and-forward operation.
Quality of Services (QoS) with priority tagging packet filtering and four priority queues per port.
Port-based VLAN, VLAN tagging - Max number VLANs is 4094.
Per port packet filtering.
Support for MAC address-based authentication methods.
Operating Modes: PRP, HSR and PRP+HSR.
Maintenance: The network is fully operational even during maintenance as any intermediate network device (such as an Ethernet Switch) can be disconnected and replaced without breaking the network connectivity.
Applications include critical network applications, smart-grid, electrical substation automation, industrial automation, critical automotive and military communication applications.

Failsafe* : In Electrical Ethernet Mode.

In-built Electrical and Optical Ethernet Interface Options. Provides both optical and electrical ethernet interface options on the “Protected side” as well as the “PRP sides”.

Ultra-Resilient and Failsafe* – Never itself becomes a point of failure in the electrical ethernet mode. The “protected interface” automatically reverts to and reconnects to the “primary PRP interface” even in a power down condition. It is the only such PRP solution available in the industry which ensures that the VCL-2724 PRP Switch, itself, never becomes a point of failure!!!
