Our systems use the Profibus PA standard. Connections carried out in accordance with the IEC 1158-2 standard, which allows the use of the network in a hazardous environment (e.g. Explosive).
In traditional systems, all process and control signals are transmitted separately through a separation barrier to the controller. Such solution significantly increases the number of connections and cables used, and of course the cost associated with the necessity of using separation barriers.
Our company offers a new approach for controlling systems in hazardous areas, offering Excom network systems. It is a fully modular remote I/O with IP20 protection, for installation in zones 1 and 2 with the possibility of connecting the digital and analog signals from zone 0. Between the controller and the I/O modules it is required to use only the transmission cable and one module separation. This allows, especially in large applications, for a significant reduction in installation and wiring costs while increasing the reliability of the system.
