Barix R6


Modbus remote I/O module with serial RS-485 Modbus/RTU interface, and 6 high current relays (230VAC,16A)



R6 is a DIN-rail mountable relay module for commercial control,power switching and home automation applications. Using the industry standard Modbus protocol over 2-wire RS-485 the device can be controlled from any Modbus capable master. Six independent relays allow the use of the Barix R6 in a wide range of switching applications:

Each relay has three connections (common,normally closed and normally open)available at screw blocks supporting wires from AWG26 /0.15mm 2 up to AWG14 /2.5mm 2 . To connect to other Barix Barionet devices the Barix R6 features two Barionet module connectors on both sides of the device carrying power and RS-485 signals (one bus cable included). Barix R6 supports Modbus/RTU protocol at speeds of 9 ’600 and 19 ’200 Bauds,with and without parity.

Up to 31 Barix extension modules can be directly connected to a Modbus Master such as the Barix Barionet and can be increased to up to 250 devices using standard RS-485 repeaters. Using the Barix Barionet, the Barix R6 can be controlled by a local Basic application (BCL) as well as remotely using TCP, UDP, Modbus/TCP and SNMP.

Barix R6 is an inexpensive solution to add high power switching capabilities to Modbus systems.

A mounting bracket is available as an accessory.
