Automation Intrinsically Safe Interfaces, Specially Tailored for Network–I/O Modules
Pepperl+Fuchs continues its long-standing partnership with Yokogawa: The automation specialists have developed a completely new integrated ISBP system with clear benefits in the field of I/O modules for intrinsically safe applications. Especially with Yokogawa I/O systems, the new unit provides unprecedented flexibility.
The result of this cooperation, Pepperl+Fuchs' Intrinsically Safe Base Plate( ISBP) is a customized Termination Board for Yokogawa’s new N-IO devices for Centum VP integrated production control system. H-System HiC isolated barrier modules,with only 12.5 mm width, can be mounted along with Centum VP N-IO modules on the ISBP. An integrated ID ensures automatic detection, the manufacturer states.
The terminals are attached directly to the ISBP board for permanent wiring on the field side, providing a clean installation as well as simplifying installation and maintenance work. Therefor, all the wiring can be completed without an intrinsically safe module being installed.
This is particularly beneficial, as the N-IO from Yokogawa supports a completely new engineering approach that enables wiring to be completed before the signal type for a specific channel has been established. In addition, the modules are “hot swappable” without making any changes to the wiring, for a complete integrated solution.
Longstanding Cooperation Bears Fruit with ISBP
Pepperl+Fuchs has designed the ISBP to the dimensions of the Yokogawa’s I/O module, using the market leading 12.5 mm wide modules. This setup ensures a perfect fit in the planning grid of the corresponding standard cabinets, making it possible to accommodate 96 channels per row on DIN-rails 1500 mm long – a significantly higher number than that offered by comparable solutions available on the market, the company claims.
"We decided to work with Pepperl+Fuchs—the market leader—due to its extremely high level of expertise and innovative capacity in the field of intrinsically safe interface systems," commented Nobuaki Konishi, Vice President of System Business Division, Yokogawa Industrial Automation Platform Business Headquarters. "Pepperl+Fuchs understand our requirements and those of our customers by making their backplane size the same height as Yokogawa standard N-IO backplane, to allow customers to maximize their cabinet space using Intrinsic Safety barriers.” ISBP can be ordered directly from Yokogawa, while all the intrinsically safe barrier modules are supplied by local Pepperl+Fuchsrepresentatives.
