ABB 266 Modbus Multivariable

266 MODBUS Multivariable


The ABB 266 MODBUS multivariable provides precise and reliable measurement of differential pressure, static pressure, temperature and diagnostic information once per second, to flow computers and RTUs. Individual device MODBUS addresses can be easily configured using the optional display or using the XMV Interface application in ABB’s Totalflow flow computers or RTUs. This application creates a “plug and play” interface to the multivariable sensor and indicates any active alarms that may be present in easily understood text. The combination of ABB’s Totalflow flow computer or RTU and one or more ABB 266 MODBUS multivariables makes an ideal solution when multi-tube measurement is required and when the transmitters must be located in a Class I, Division I hazardous location.
