Isolated Bus Transceiver Modules

Relec’s range of CAN/RS485/RS232 transceiver modules integrate a transceiver, isolation chip and high efficiency isolated dc dc converter in one single module. Their compact size, low power consumption and high reliability  make them suitable for use in harsh industrial environments.   We can supply modules in either CAN bus, RS232 or RS485 formats.  Our technical team are on hand to take you through the advantages of each format.

The Controller Area Network (CAN) bus, originally developed for data communication automobile networks, is a robust differential signalling, serial communications system. It has quickly gained acceptance into a variety of industries including automotive, aerospace, industrial machinery, medical systems, agricultural machinery, marine control, navigation and elevator control systems, amongst others.

Relec’s CAN transceivers solve specialised networking requirements for various applications and power supply systems, providing solutions for 5 Volt, 3 Volt operation as well as CAN FD (Flexible Data rates).

Traditional transceivers can only receive and send data, which requires an external isolation chip/opto-coupler and isolated dc dc converter to complete the solution.

The new integrated Isolated CAN transceiver modules highlighted below, provide a combination of transceiver IC, isolation chip, opto-coupler and isolated dc dc converter in a single package.
