ATEX valve islands for Zone 2-22
ASCO Numatics 501 series valve islands with the G3 and 580 electronics are certified to ATEX category 3 zone 2-22 for explosive atmospheres, enabling the benefits of the G3 electronics to be applied to a wider range of installations. When mounted in an IP65 or Ex e cabinet, the valves are certified II 3G Ex nA IIC T4 Gc X for gas and II 3D Ex t IIIC T85°C Dc IP65 X for dust.
The 501 series valve islands, with G3 or 580 electronics offer increased intelligence in the form of new diagnostic functions and a graphic display (in place of the usual LED indicators). The display supports plain-language messaging of diagnostic information at both the module and communication node level. The
G3 series product line is a completely modular system that uses an innovative clip design, allowing easy module removal/replacement without dismantling the whole manifold. The
580 series product line offers a compact, affordable fieldbus electronics platform and can be used when you don't need the advanced distribution features of the G3.
The ATEX certification covers 3/2-5/2-double 3/2 NC-NC – 5/3 valves over a temperature range of -10 to +50°C. The valves come up with a flow rate of 400 l/min ANR. Each manifold can have up to 32 coils maximum with up to 32 coils energised simultaneously when using in combination with the G3 electronics. Certification also covers ProfiNet Ethernet/IP™, Modbus/TCP, Devicenet and Profibus® protocols, round M23 and sub-D 37 multipin connector and 16 and 8 way digital and analogue input/output modules.
