The Ex20 extension enables the expansion of Elara connectivity and can be connected to Techbase via Modbusdifferent gateways like the Elara, Techbase, and Axiomtek.
With the Ex20 connected to the Elara gateway tray/metal box, a greater quantity of analog and digital sensors may be connected to the Elaragateway.
