DX99 FlexPower nodes from Banner Engineering are intrinsically safe wireless communication nodes certified for worldwide use in explosive gas or dust atmospheres for use in Class I, Division 1, Groups A, B, C, D; Class II, Division 1, Groups E, F, G; Class III, Division 1; Category 1G, Group IIC, Zone 0; and Dust, Category 1D, Group II, Zone 20. These nodes interface with many sensors and other monitoring and control devices and are available with a wide range of I/O options. They collect data and transmit control commands between the sensors and a central Gateway. Up to 56 nodes can be connected to one Gateway. The Gateway maps inputs from the remote nodes and interfaces with a PLC or HMI via RS-485 modbus or Ethernet/IP.
