The CATAN C1 EN controller is the central component of the Catan product family for building and room automation. The compact REG housing with an overall width of just 6 HP fits in all electrical distributors. The highly 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, 0 V ... 10 V interfaces, or as meters, among other things. Alternatively, outputs can be configured as digital inputs. The controller is equipped with a managed switch (3 x 1 Gbps). Emalytics and the Niagara Framework are a powerful tool available as the programming environment. This makes it possible to integrate protocols such as BACnet, KNX, Modbus, and much more, and provides functions from room automation to HVAC and visualization. Easy cloud integration is possible as a building IoT controller.
