GSM remote control relay | 7 channels | 230VAC/30VDC | 10A | NO + COM | SMS and call control

GSM remote control relay | 7 channels | 230 V AC / 10 A | SMS and call control | whitelist up to 200 numbers | GSM-RELAY

GSM-RELAY – an electronic 7-channel GSM remote control module with an integrated GSM modem, designed for remote switching of electrical equipment and control circuits using a mobile phone. Control is performed by phone call or SMS commands, allowing the device to be operated from any location where compatible GSM communication is available.

The controller has 7 separate relay outputs. The first relay channel can be controlled by a phone call, while all relay outputs can be controlled by SMS commands. When controlling the first relay by call, it is possible to select either a momentary pulse or toggle ON/OFF mode.

Each relay output has NO and COM contacts. The maximum contact load of one output is 230 V AC / 10 A or 30 V DC / 10 A. The load must be powered from a separate electrical circuit – GSM-RELAY acts only as its switching contact.

Control access is protected by a 6-digit password and an authorised phone number list. Up to 200 authorised numbers can be stored in memory. GSM signal quality and relay output status can also be checked, output operating time can be set, and it is possible to choose whether relay states should be reset or retained after a power failure.

GSM-RELAY is a 7-channel GSM remote control relay that allows seven separate circuits to be controlled by phone. The first relay can be activated by a call, while outputs 1–7 can be controlled by SMS commands. The device supports up to 200 authorised phone numbers, password protection, relay pulse and toggle modes, GSM signal checking and remote relay status control.

Remote control: one module allows control of up to 7 separate outputs, while the first channel can additionally be activated by a standard phone call.

Important: do not exceed the permitted 230 V AC / 10 A or 30 V DC / 10 A contact load per output. For larger loads, use a suitable external relay, contactor or another power switching device.

Relay states are represented as a sequence of 7 values: 1 means ON, 0 means OFF. This makes it possible to control several circuits or check all their states using a single SMS.

Caller ID + White List: caller number identification makes it possible to restrict access and grant control only to pre-registered phone numbers.

For security: after configuring the device for the first time, it is recommended to change the factory password to a personal one and store it securely.

Important: a SIM card with an active PIN request will prevent the controller from operating normally. Disable the PIN request before inserting the card into GSM-RELAY.

Do not confuse the two voltages: 9–12 V AC/DC or up to 24 V AC/DC is the power supply for GSM-RELAY itself, while 230 V AC / 10 A is the maximum load switched by the relay contacts.

• heating control circuits;
• air-conditioning and ventilation control;
• lighting control circuits;
• control of gates, doors or other pulse-controlled automation systems;
• control of pumps or other equipment via a suitable contactor or external relay;
• other domestic and automation control circuits.

1. Choose a location with sufficient GSM signal from the selected operator.
2. Disable the PIN code request on the SIM card.
3. Insert the SIM card in the correct orientation and lock the SIM holder.
4. Connect a 9–12 V AC/DC power supply; up to 24 V AC/DC may be used.
5. Connect the NO and COM contacts of the required relays to the controlled circuits.
6. Do not exceed 230 V AC / 10 A or 30 V DC / 10 A per contact.
7. Wait until the device registers on the GSM network.
8. Configure the password, authorised numbers and required relay modes.

• A suitable and active SIM card is required for control.
• The SIM card PIN request must be disabled.
• The installation location must have sufficient GSM signal from the selected operator.
• Check whether the GSM frequency range used is compatible with your mobile network.
• Controller power supply – 9–12 V AC/DC; up to 24 V AC/DC may be used.
• Each relay has NO + COM contacts.
• The contact load of one output must not exceed 230 V AC / 10 A or 30 V DC / 10 A.
• Use an external relay or contactor for higher-power loads.
• OUT1 can be controlled by call, while all 7 relays can be controlled by SMS commands.
• Commands must be entered in uppercase letters.
• Change the factory password before starting permanent use of the device.
