Intrinsically Safe Wireless Communication for EX Areas from Banner Engineering

Designed for worldwide applications where wiring is impractical or unaffordable, Banner Engineering’s (Belgium) DX99 nodes and the devices they monitor are battery powered, enabling easy and reliable signal transmission up to 3 km from explosive atmospheres.

Metal housing nodes are configured with internal battery, and can be connected to any kind of sensing device with digital or analogue output. DX99 Metal housings are ATEX and CSA certified for explosive dust and gas atmospheres, to be used 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. Nodes are IP67 rated and provide simple DIP switch configuration.

Transceivers provide bidirectional communication between the Gateway and Node, including fully acknowledged data transmission. Lost RF links are detected and relevant outputs set to user-defined conditions.

The DX99-D4 can operate in RS485 Modbus RTU Mode to connect any 3^rd party Modbus Slave sensor, and in Analogue Mode to connect 1-5VDC Pressure Transducers for very long battery life. The DX99-D5 is specifically designed to work with 4-20mA flow meters, pulsed or guided-wave Radar with up to 60 seconds warm-up time.

The DX99 FlexPower nodes expand the capability of Banner Engineering’s SureCross wireless solutions to hazardous applications in numerous industries including water treatment, waste management as well as coal, mining, oil & gas, grain handling, power generation, cement.
