## Description

GSM relay module for opening gates and remote control of equipment, activated by free call or SMS, works on the 4G network and is easily configured with SMS commands, allows authorization of up to 999 users for secure access, has relay with COM NC NO contacts, removable external antenna and DIN rail mounting.
Relay module with remote control via GSM that can be used to open gates, doors or to remotely control any kind of device or equipment.
The module is the 4G version , different from the standard version that only supports the 2G network.
The relay is activated by direct call to the card installed in the module or by SMS message. Call activation is convenient because the module will not answer the call but will reject it after the first "beep" thus avoiding call charging. After receiving the call, the module will send a text message to the caller informing him of the relay status.
All settings are made via SMS commands (you will receive a list of commands in the package) and security is provided by the possibility of registering up to 999 users in the module's memory. The module will only respond to commands received from registered numbers.
Also via SMS, settings can be made such as how long the relay will have to maintain the activated state. The factory-set time is 0.5 seconds but can be modified by SMS command (the time communicated via SMS represents a unit of 0.5s, so, to remain active for 10 seconds for example, you will have to send the command for double. If you want to permanently maintain the relay active until the next call, set the time equal to 0.
The module comes with a detachable external antenna and a Nano SIM card slot. The output relay has COM, NC and NO ports. A physical button can be attached to the same module to actuate the relay.
It can be mounted directly on the rail.
