Intrinsic safety, I.S., interfaces are implemented between the process sensors and the major control system. The transmitted signal from the I.S. interfaces can be analogue, digital or HART®.
PR electronics’ I.S. interfaces are marketed worldwide and designed to meet the terms of the strictest international standards from the processing industry. Thus, the modules for I.S. signal conditioning comply with both European and American standards.
ATEX is the name of a European directive concerning material for hazardous atmospheres. The I.S. interfaces are adapted to this directive and meet the demands of the EN 50014, EN 50020 and EN 50282-1-1. Thus, the I.S. interfaces are certified to function as associated equipment for potential hazardous atmospheres. According to the ATEX directive the I.S. interfaces from PR electronics can function in the following potential hazardous areas:
Furthermore, several of the I.S. interfaces are certified according to UL 913 - the American I.S. standard. These modules can be used in connection with the following areas:
The universal uniqueness of the 5000B-series offers the customer many concrete advantages:
|Emerson||Delta V / Delta V SIS|
|GE-Fanuc||90-30 / 90-70|
|Invensys||Triconex TMR PLC|
|Mitsubishi||Melsec Q series|
|Schneider Electric||Modicon Quantum / Modicon Premium|
|Siemens||S7 - 300|
|Yokogawa||Centum CS3000-R3 / Prosafe|
The reduction of manual wiring is another obvious advantage of the backplane. The wiring from the control system to the signal conditioning devices is replaced with a multi cable with e.g. a 25-pole SUB D connector. Totally, the backplane replaces up to 56 wires.
