 | Feature List |
- 6 relays (250 VAC 16 Amps,NO &NC)
- RS-485 serial interface
- Protocol:Modbus/RTU
- Two Barionet module connectors for additional relay extensions, I/O devices, power modules, temperature sensors etc.
- DIN-rail mountable
 | Description |
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:
- Switching power (lights,blinds,heating,power relays,motors)
- Activate bells,door strikes,indicators and alarms
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.
