DavidDAViD provides 2 output relays X and Y (each allows up to 5A/250V) 4 input A to D for SMS reporting (the inputs react to a connection or disconnection to or from GND) David can be configured via SMS, USB or from Configuration web page David can be used as: A switch with SMS remote control. SMS texts for switching particular terminals on/off are configurable. A time-switch which can be activated remotely via a mobile phone (the switch-on period is configurable from 1 second to 10 hours). A relay with dialling-in remote control. Up to 50 tel. numbers can be authorized for each relay. Because calls are not answered dialling-in control within GSM is free of charge. (David only checks the caller’s number and - if the number is authorized - responds with relay activation.) This can be used for parking latch control etc. A relay with validity-limited dialling-in remote control. Each authorized number can have a limit to the number of calls. When the call count reaches the limit the tel. number is de-authorized. This can be useful for pre-paid services such as e.g. parking. Any tel. number can be re-authorized via SMS by the administrator. An SMS reporter. Input A to D activations or deactivations can be reported by SMS and optionally confirmed by phone calls. Each input can have its own message texts and up to 8 tel. numbers programmed.
