What Are Intrinsic Safety Barriers?
At PLC Chain, we work towards offering high-quality intrinsic safety barriers to protect people and equipment working in hazardous conditions. Such devices are implemented to regulate current, voltage, and overall energy in a manner that ensures electrical signals are safe to connect to instruments in areas where explosions might occur. Solutions such as the Pepperl Fuchs safety barrier can be used to ensure that safety is achieved at a very high level without compromising on reliability.
How Intrinsic Safety Barriers Prevent Explosions
The primary purpose of using an electrical isolation safety barrier is to contain potentially hazardous energy at a distance from risk zones. It is effective in that it restricts the quantity of electrical power that may pass into the instruments, like transmitters, sensors, and alarms. When there is excess energy, the obstruction redirects it. This prevents sparks/or overheating, and short circuiting that would cause an explosion.
Types of Intrinsic Safety Barriers
We offer different barrier designs to meet specific requirements, including:
● Zener barriers – simple, cost-effective, and reliable for basic applications.
● Galvanic isolators - isolator types provide the electrical isolation safety barrier without the requirement of grounding.
● Pepperl Fuchs safety barrier - a durable barricade that meets the stringent international standards.
Key Features to Consider When Selecting an Intrinsic Safety Barrier
Things to consider when choosing a safety barrier:
● Voltage and current ratings
● Number of channels needed
● Compatibility with devices such as transmitters, solenoids, and flow meters
● Certifications and approvals for your industry
● Extra features like LED indicators and replaceable fuses
Specifications and Standards for Safety Barriers
Every project requires compliance with strict industry approvals. Our intrinsic safety barriers can pass various leading certifications like ATEX, UL, CSA, and FM. We cooperate only with the most trusted manufacturers, such as Pepperl Fuchs, thereby guaranteeing that the products supplied to you meet the highest safety and reliability standards.
Comparison of Zener Barriers vs Galvanic Isolators
● Zener barriers are simple, affordable, and reliable, but require grounding and cause some voltage drop.
● Galvanic isolators provide full isolation between circuits, need no grounding, and are ideal for complex installations.
Both solutions are essential, and the right choice depends on system requirements.
