Explosion Proof Signals: Hazardous Area EXD Push Buttons

PB150 & PB125 EXD Push Buttons carry ATEX: II 2G Exd IIC T4 T6 (Incorporating IIA & IIB) approval and the PB135 Push Buttons carry ATEX: II 2G Exd IIB +H2 T4 - T6 (Incorporating IIA) for use in potentially explosive atmospheres, hazardous areas and very harsh environmental conditions . Customers can choose between the two options available: GRP (Glass Reinforced Plastic) and Stainless Steel. Both push buttons are compatible for use with a PLC, DCS and ESD systems via 4-20mA output and ideally suited for use in fire alarm systems and an addressable option with diode fitted is available. The full range of EXD Push Buttons including product specifications can be viewed below.  

 

APPLICATION: The EXD Push Button range is suitable for applications in the following environments: Oil and Gas, On-shore and Offshore, Chemical, Petrochemical, Refineries & Marine locations.

The PB150 push button range has been approved for use in potentially explosive atmospheres and harsh environmental conditions.

Typical applications are Oil and Gas, On-shore and Offshore, Chemical, Petrochemical, Refineries & Marine locations etc.

It is compatible for use with a PLC, DCS and ESD systems via 4-20mA output. It is ideally suited for use in fire alarm systems and an addressable option with diode fitted is available.

The unit has the option for either a key reset or self reset. The range also offers an additional visual LED indication option; red, green (or both) can be fitted. When fault or alarm status arises the green LED will be overridden by the red LED. The design allows for termination inside the unit.
