Overview
GSM Relay Switch with External Antenna 4 Bands DC 9–24 V Black Silver Design for Remote Control of Gates

The GSM relay switch with external antenna is a device designed for the remote control of gates, doors or electrical systems using a mobile phone. Control is achieved by simply calling from an authorised phone number, without the need for a remote control or physical key.

The device operates in quad-band GSM mode (850/900/1800/1900 MHz), allowing its use in various mobile networks worldwide. This makes it suitable for installations in both residential and commercial properties where reliable remote switching is required.

Included is an external antenna with a 50Ω SMA connector, which ensures better signal reception and more stable communication. This is particularly advantageous in areas with weaker coverage. The GSM relay allows not only the switching on and off of devices but also access control, for example, to gates or parking systems.

Users can be managed via SMS commands, which allow for their addition or removal. Up to 200 authorised phone numbers can be stored in the system. Unknown numbers are automatically ignored, enhancing the security of the entire system. The relay activation time is programmable as needed.
