Barix 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.
Each output is capable of sourcing up to 1.5A drawn from a DC power supply (5 to 30V over separate supply terminals). For thermal reasons the total current should not exceed 6A which leaves 0.5A 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 per second). At the same time each signal is filtered (de-bounced) and stored in a state register for dry contact and push button applications.
Separate removable screw terminal blocks supporting wires from AWG 28/0.08 mm2 up to AWG 16/1.3 mm2 are provided for power input, RS-485, inputs and outputs. To connect to other Barionet devices the Barix IO12 features two extension connectors on both sides of the device carrying power and RS-485 signals (one extension cable included).
Barix IO12 supports Modbus/RTU protocol at speeds of 9600 and 19200 Bauds, with and without parity and is a low cost alternative to add I/O capabilities to Modbus 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 IO12 can be controlled by a local basic application (BCL) as well as remotely using TCP, UDP, Modbus/TCP and SNMP.
