Intrinsic safety
SI interfaces are installed between the process sensors and the main control system. The signals delivered by the SI interfaces are analog, logic or HART.
PR electronics' SI interfaces are distributed worldwide and meet the requirements of international process industry standards. Therefore, SI signal conditioners meet European and American standards.
The ATEX expresses the European directives relating to equipment mounted in explosive areas. The SI interfaces are adapted to these directives and comply with the rules of standard EN 50 014, EN 50 020 282-1-1. Thus, the SI interfaces are certified for operation associated with equipment for an explosive area. In accordance with the ATEX directive, the PR electronics SI interfaces can operate in potentially hazardous areas as follows:
Group 2 (surface industry)
In addition, several SI interfaces are certified according to the American standard UL 913.
These modules can work in areas such as:
The universal originality of the 5000 B series offers the customer many concrete advantages:
Assembly plant
The 7300 board is the ideal choice when there are 4 or more modules to integrate into a process. The 7300 plate stands out for its great flexibility:
Connections suitable for DCS systems
Standard or IS modulesThe standard connection allows integration with the vendors of the following systems:
The 7300 board also saves a lot of time on wiring. The cable between the control system and the modules is replaced by a multiple cable with for example a SUB D 25 connector.
