WAGO I/O Devices Earn ATEX, IEC Ex Certifications
October 2011 – Nearly 30 couplers, controllers and I/O modules from WAGO Corporation’s WAGO-I/O-SYSTEM now carry ATEX and IEC Ex Certifications for operating in temperatures up to +60°C. This extends fieldbus-independent support of the WAGO-I/O-SYSTEM to a variety of hazardous apps in dust-laden process (corn/coal mills, cement and bio-gas plants) and energy management (gas/oil production) industries.
Although designed for Zone 2/22 and non-hazardous locations, the WAGO-I/O-SYSTEM safely integrates signals from sensors/actuators via Ex i segments. Components in Zones 0/22 and 1/21 that serve Ex i applications can be cost-effectively integrated into higher-level control systems without additional components, such as Intrinsically Safe barriers.
WAGO is the leader in spring pressure connection technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products: DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; the WAGO-I/O-SYSTEM and more.
