Security Services & Risk Management
The fieldbus system, by the very nature of the environment in which it will be placed, is at risk from surges across the fieldbus system. Because the fieldbus system is controlling and handling the data transactions across a common trunk, the importance of safeguarding the integrity of the fieldbus system is paramount in order that the shutdown of the multiple processes does not occur. These fieldbus solutions can be applied without impacting the length of the fieldbus run or the number of devices.
MTL surge protection devices supply complete fieldbus protection, whether for AC power, transmitter or trunk protection - MTL Surge Technologies supplies that power protection. The FP32 devices provide surge protection along the trunk or spurs of fieldbus systems from damaging the associated electronics such as terminators, spur blocks and the bus control equipment. Fully automatic, the FP32 reacts immediately to ensure that the equipment is never exposed to damaging surges, by directing surges safely to earth, and then resets automatically. Its small footprint also allows the FP32 to be located near terminators and spur blocks.
* DIN rail mounting for easy installation.
* Meets the requirements of IEC61158 - 2:2000 for Foundation Fieldbus.
* Plug connectors for quick and easy connection or rewiring.
* 20 kA maximum surge current.
Technical application notes are available for free.
