    Product Description

    Four-, five-, six-, seven-seat explosion-proof control and indication posts of the PKIV series with Ex d protection type made of aluminum alloy with alloying modifiers are designed to control equipment and/or provide indication signals both on-site and remotely in a hazardous area.
    The PKIVA 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 (ESS). When ordering equipment, please specify the "/SIL2" option and indicate its intended purpose in the comments: emergency stop, emergency start, or a combination of both. Whether the "/SIL2" option is applicable depends on the control station configuration.

    Advantages

    • Certified equipment ensuring safety and uninterrupted operation.
    • The enclosure made of aluminum alloy with alloying modifiers combines exceptional mechanical strength and corrosion resistance.
    • 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/IP69.
