Handling flammable and potentially explosive substances is part and parcel of everyday operations in manybranches of industry. However, it is not possible to do without the advantages of automation even in these sectors. Consequently, there must be a protection system to allow safe and, at the same time, efficient operation when using field devices such as sensors and actuators. Such a system can be achieved for instance by the use of type of protection intrinsic safety i۫.The modern ISpac isolator system from R.STAHL is the ideal safety lock۫ between the safe electronic signals and the Exi signals...

Contact 1 SignalSignal Contact 2 ISpac 9162 13 Characteristics Monitoring of measurable variables that are acquired by sensors in the field can be implemented easily andefficiently with the aid of limit value switches.The ISpac isolators with limit value evaluation allow the user to define his or her own individual limit values. If the individual limit value is overshot or undershot, this is signalled by a contact.Temperatures, rotational speeds or any other measured values can consequently be monitored flexibly and at distributed locations. R.STAHL offers limit value switches for temperature...

The process industry frequently requires systems for protecting life, limb and the environment.This relates to functional safety of installations and systems in accordance with IEC EN 61508/61511. SIL is considered the yardstick of safety-related performance of an electronic or electrical control system. Most of the components of R.STAHLs ISpac Exi isolator system can be used in applications necessitating SIL 2 or SIL 3. ISpac isolators can consequently be used easily with no price markup for transmission of safety-related and conventional signals or a mix of both. As a manufacturer of explosion...

15 Chemical and petrochemical installations are installed worldwide, prerequiring competent, internationalcooperation during the project planning, construction and operation phases.The required technology must be able to be used worldwide. R.STAHLs ISpac isolator system is approved in accordance with ATEX, FM, UL and GOST, besides many other international standards. Climatic conditions are also a crucial selection criterion. ISpac can be used over a broad ambient temperature range extending from --20ҰC bis +70C. In addition, R.STAHLВs own Competence Centres allow implementation of individual,...
