The modular FACP FlexES Control concept offers three pre-configured, factory-made bundles (FX2, FX10, FX18) for operating up to 2, 10 or 18 modules. The FlexES Control bundle can, however, also be adapted to individual requirements by using separately provided components. Depending on the system's design, it might be necessary to use an expansion housing unit for the batteries and an additional power supply unit. The FlexES system provides a Master & Slave Control Module (CPU), galvanically isolated loop modules and up to three cascadable and redundant Power Supply Units each with 150W (same or different main). As well it’s delivered with a dust filter, which is proven in use in typical applications with dust-laden environment and/or sanddust regions. System supports up to 254 digital loop addresses in total.
