Barix IO 12

The Barix Barionet IO12 is a DIN mountable, I/O units for commercial control, signaling, switching, sensing and counting applications.

Using the industry standard Modbus protocol over 2-wire RS-485 the device can be controlled from any Modbus capable master.

Twelve outputs allow the use of the Barionet IO12 in a wide range of switching and signalling applications such as switching DC power for controls, fans, motors and relays or activating bells, door strikes, lamps/indicators and alarms etc.

Twelve opto isolated electrostatic discharge protected inputs are powered in groups of 4 by 3 separate external power inputs. For counting applications each input signal is directly fed into a counting register (up to 100 pulses/second) At the same time each signal is filtered (debounced) and stored in a state register for dry contact and push button applications.

Separate removable screw terminal blocks supporting wires from AWG28 / 0.08MM² UP TO awg16 / 1.3mm² are provided for power input, RS-485, inputs and outputs. To connect to other Barionet devices the Barionet IO12 features 2 extension connectors on both sides of the device carrying power and RS-485 signals (one extension cable included). A mounting bracket is available as an accessory.

Barionet IO12 supports Modbus/RTU protocol at speeds of 9,600 and 19,200 Bauds, with and without parity and is a low cost alternative to add I/O capabilities to Modbus systems. Up to 31 Barionet extension units can be directly connected to a Modbus Master such as the Barionet and can be increased to up to 250 devices using standard RS-485 repeaters.

Using the Barionet, the Barionet IO12 can be controlled by a local Basic application (BCL)as well as remotely using TCP, UDP, Modbus/TCP and SNMP.
