Overview

Overview of CAN / CANOpen / DeviceNet Redundant Link Module

This product is a Fieldbus Link Redundant Module for CAN bus. It realizes the mutual conversion of single bus and double redundant bus. Field devices equipped with only a single CAN bus interface, can be integrated in the redundant CAN bus network by using the Redundancy Link Module. Acting like an active switch, it converts two redundant lines to one CAN line or vice versa.
The Link Redundant Module amplifies signal form and amplitude of the incoming data and monitors activities and error statuses of all three lines.
The series conforms to the fieldbus based on the CAN2.0A/B protocol, such as CAN, DeviceNet, CANOpen, SDS, NMEA2000, SAE J1939, SAE J2284, the rate is set by the DIP switches (recommended) or the selection rate adaptive setting.
The product is industrial grad designed, casing: IP40 protection, DIN rail mounting, DC (9~36V) power input, support ports error alarm output, dual redundant power input and isolation protection. -40~75°C Operating Temperature, can meet various Industrial situation.
