    Safely transmit power to switches and sensors in highly volatile areas. Commonly used in refineries, power plants, and wastewater-treatment facilities, these barriers use a NAMUR signal to reduce the current and voltage coming from your power supply—preventing sparks and ignition. While these barriers connect to switches in hazardous locations, they must be installed in a separate nonhazardous area, along with the power supply. As associated apparatuses for IECEx and ATEX internationally certified switches, they should be paired with items that have corresponding ratings. Mount to DIN rails inside control cabinets and electrical panels.
    Relay Signal Output—Barriers with a relay signal output are slower than those with a transistor output, but they can handle higher AC and DC loads. Because of their moving parts, they wear out quicker than transistors. Use them to turn devices on and off, such as light bulbs and small motors.
    Transistor Signal Output—Barriers with a transistor signal output are faster and last longer than those with a relay output. However, they can only be used to handle DC loads. Connect them to receiving devices, such as remote displays and programmable logic controllers (PLCs).

    Add these guards to hot sticks, also known as high-voltage switch operating sticks, to keep hands away from danger. Made of nonconductive plastic, they act as a barrier between your hands and high-voltage areas. They help you comply with safety regulations for operating hot sticks. Their red color stands out against the yellow of most hot sticks, and it won’t wear off over time. Slide these guards onto your hot stick and secure them with a screw on each side.
