Intrinsic safety using single-channel safety barriers
Using R. STAHL’s single-channel safety barriers, you can make HART transmitters, zero-potential contacts, temperature sensors, solenoid valves, indicators and much more intrinsically safe. They can be combined in many different ways, occupy a limited amount of space and require very little maintenance.
R. STAHL’s standard single-channel safety barriers feature linear current limiting. Variants with electronic current limiting are also available for intrinsically safe field devices with high energy requirements such as solenoid valves.
Their wonderfully simple design means that not only do they take up very little space, but you can also expect an impressively long service life. To install them, all you need to do is snap them onto the DIN rail. This action has the added advantage that it equalises the potential between the conductive parts, saving you both time and money. All variants use the same, interchangeable back-up fuse, which reduces the storage requirements for back-up fuses needed for maintenance.
R. STAHL’s experts are always on hand to help you choose the right single-channel safety barrier for your needs, decide whether equipment can be classified as simple equipment and acquire the intrinsic safety certification required by law.
