The CE-AD91 Data Logger extension enables the expansion different gateways like the Ultragate, Elara, Techbase, and Axiomtek.
With the CE-AD91 Data Logger connected to the gateway tray/metal box, a greater quantity of analog and digital sensors may be connected to the gatewayImage - TBA
SPD is a device designed to protect electrical systems and equipment from voltage surges caused by lightning strikes, power grid fluctuations, or switching operations. It works by diverting excess voltage away from sensitive components.
