Arcus-EDS is a German manufacturer of KNX gateways and sensors. Its range on KNX MORE covers gateways that bring Modbus RTU, M-Bus meters, smart meter ports, DMX512 lighting and RS232/RS485 serial devices onto KNX, together with PT1000 temperature probes, humidity and weather sensors, and system devices such as KNX chokes and IP interfaces.
Compare interfaces, mounting (DIN rail, in-wall or surface IP54/65) and number of datapoints, then add the devices to the project planner.
Frequently asked questions
How do I connect Modbus or M-Bus equipment to KNX?
Use a KNX gateway for that protocol: a Modbus RTU gateway over RS485 or RS232, or an M-Bus gateway with the number of meters you need. The gateway maps the device's values to KNX group addresses that ETS and visualisations can use.
What is a PT1000 sensor?
A platinum temperature sensor whose resistance is 1000 ohm at 0 °C. PT1000 probes are used for pipes, tanks, outdoor and room temperature, and connect to a KNX input that supports PT1000.
Which mounting should I choose?
DIN rail versions go in the distribution board, in-wall versions behind a cover, and surface versions with IP54/65 suit plant rooms and outdoor or damp locations.
