Barix R6 is a DIN-rail mountable relay module for commercial control, power switching and home automation applications.<br>Using the industry standard Modbus protocol over 2-wire RS-485 the device can be controlled from any Modbus capable master.<br>Each relay has three connections (common, normally closed and normally open) available at screw terminal blocks supporting wires from AWG 26/0.15mm² up to AWG 14/2.5mm².<br>To connect to other Barix devices the Barix R6 features two extension connectors on both sides of the device carrying power and RS-485 signals (one extension cable included). Barix R6 supports Modbus/RTU protocol at speeds of 9600 and 19200 Bauds, with and without parity. Special commands have been added to the Barionet R6 to support also non Modbus native control systems. Up to 31 Barix extension units 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.<br>Barix R6 is a low cost alternative to add high power switching capabilities to Modbus systems.
