The Catan C1 EN controller is designed for building and room automation. The compact REG housing has an overall width of 6 HP to fit in all electrical distributors. The flexible mix of inputs and outputs leads to further space and cost savings. Each channel can be configured individually: universal inputs are suitable for temperature sensors, 0V-10V interfaces, or as meters. Alternatively, outputs can be configured as digital inputs. The controller is equipped with a managed switch (3x1 Gbps). The controller’s programming environment features Emalytics and the Niagara Framework, enabling the integration of protocols such as BACnet, KNX and Modbus. The controller provides functions ranging from room automation to HVAC and visualization. Cloud integration is possible when using the Catan C1 EN as a building IoT controller.
