Overview
Honeywell Zone 1/21 IO is ATEX & IECEx certified, Intrinsically Safe designed a remote I/O system for direct installation in Zone 1/21 hazardous area. Communication over Profibus-DP, ProfiNet and EtherNet/IP helps for fast & seamless installation and integration at scale while keeping low efforts and cost. Honeywell Zone 1/21 IO system is available to sell only in India.
What Is It?
The Honeywell Zone 1/21 IO is a modular, intrinsically Safe designed remote IO system along with ATEX and IECEx certification, allows to install directly in Zone 1/21 and Zone 2/22 area. This provides redundant communication, redundant power supply, HART-capable galvanic isolated IO channels, RIUP enabled (Removal & Insertion Under Power) modules with extended operating temperature -20 °C to +75 °C.
How Does It Work?
Field instruments from Zone 0/20 directly connect to Honeywell Zone 1/21 IO System which further integrate with any control system over Profibus-DP, ProfiNet or EtherNet/IP protocols, allows fast & seamless installation and configuration. Honeywell Zone 1/21 IO system delivered as ready to install, complete integrated solution which includes SS304/SS316L enclosure, Power Supply Modules, Communication Gateway Modules, IO Modules, necessary accessories etc. Honeywell Zone 1/21 IO system is tightly integrated with Honeywell DCS and PLC system.
What Problem Do They Solve?
Honeywell Zone 1/21 IO unlock the possibilities for monitoring and control of IS / Non-IS field instruments of Zone /20 Hazardous area by having remote IO system near to field. Ready-to-install solution help for cost saving & less installation efforts, improve safety, and comply with environmental regulations:
