Barix Barionet IO12 is a DIN-rail mountable I/O unit 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 signaling applications:
Each output is capable of sourcing up to 1.5 Amps drawn from a DC power supply (5 to 30 Volts over separate supply terminals). For thermal reasons the total current should not exceed 6 Amps which leaves 0.5 Amps per output when using all outputs.
Twelve opto isolated electro static 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 two 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 Barix Barionet 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 Barionet IO12 can be controlled by a local Basic application (BCL) as well as remotely using TCP, UDP, Modbus/TCP and SNMP.
