Description


GSM Key is GSM relay management device that uses GSM network for managing one relay output with free call. Managing of relay output is allowed to numbers defined in list that can contain up to 200 GSM numbers. It is possible to adjust the device with  SMS, and to get report about digital input status. Standard RS232 connector is used for simple adjusting of parameters through PC terminal.  Antenna is connected on female  SMA 50Ω connector. State of the device is indicated with four LED diodes. Device is powered with 8V to 30V dc voltage and is suitable for DIN 35mm rail mounting.

 

 

Application

-      Managing (open/close) electrical gates and barrier gates with free call

-      Door opening and switching lights in objects with interphone systems with free call (buildings, companies ...).

-      Using cell phone as remote controller.

 

Function

GSM key enables remote management by one free call using one relay output. Device can be configured to send SMS about status changes on digital input. Input and output are galvanicaly isolated, thus enabling easy implementation into system. Relay output has high current capacity, so it can directly drive devices working on 220V.
