    Product Description

    The PKIVA-NT series explosion-proof single-, double-, and triple-seat control and indication stations with Ex d protection ratings are made of stainless steel and are designed to control equipment and/or provide indication signals both locally and remotely in hazardous areas. Suitable for use in underground mines and workings.
    The PKIVA-NT control and indicating stations have received a SIL 2 functional safety certificate. This certification confirms that the equipment operates reliably during operation, ensures functional safety, and can be used in emergency shutdown systems (ESPS). When ordering the equipment, please specify the "/SIL2" option and indicate its intended purpose in the comments: emergency shutdown, emergency start, or a combination of both. Whether the "/SIL2" option can be used depends on the control station configuration.

    Advantages

    • Certified equipment ensuring safety and uninterrupted operation.
    • Stainless steel body ensures product durability.
    • Ergonomic design of control, indication, monitoring and signalling elements.
    • The large size of the controls allows you to work with gloves, which is important when working outdoors in low temperatures.
    • The indicating elements have a large diameter of 40 mm and are equipped with a reflector, which allows the signal to be clearly seen at a wide viewing angle and with varying surface contamination.
    • There is a wide selection of control, indication, monitoring and notification elements of standard design, as well as non-standard designs, manufactured according to customer requirements.
    • Protection against mechanical damage IK10 and a high degree of protection against moisture and dust IP66/IP67.
