How to take advantage of the GSM 4G controller in your home or office

GSM 4G LTE Controller is a practical solution for remote control of various devices and systems. Its biggest advantage is simplicity - control is done through a simple phone call or SMS message, without the need for the Internet or complicated applications.

This kind of device allows you to turn on or off the gate, ramp, pump or lighting from anywhere, but also to receive a notification about the state of the inputs (eg when a sensor or switch is activated).

The main advantages of using a GSM 4G LTE controller

• Remote control of devices - opening the gate or turning on the pump with a single call or SMS.

• Reliable operation without internet - the device uses the GSM network, which means that it works even where there is no Wi-Fi signal.

• Notifications and alarm calls – when one of the inputs is activated (e.g. a sensor), the device sends an SMS message or calls a priority number.

• Multi-user support – up to 20 administrators and 200 users, which makes it suitable for both private and business applications.

• Output flexibility – 2 relay outputs with different operating modes (impulse, permanent, timed), which allows adaptation to needs.

Practical applications

1. Gates and ramps - opening via a call without call costs (the device rejects the call, and the relay is activated).

2. Pumps and motors - turning on/off water or heating pumps from any location.

3. Lighting and electrical appliances - turning on and off lights or other consumables according to a predefined mode.

4. Warning systems - detection of an alarm state through sensors connected to inputs and sending SMS notifications.

Technical characteristics (summarized)

• Operating voltage: 230V AC / 5W

• Outputs: 2 relay outputs (NO/NC)

• Inputs: 2 digital inputs (high/low activation)

• Relay: 250VAC / 30VDC – 5A

• Output management: SMS or call (output 1 – call and SMS, output 2 – SMS)

• Number of users: up to 200 + 20 administrators

• Dimensions: 100 × 100 × 40 mm

• Operating temperature: –25 °C to +60 °C

Conclusion

The GSM 4G LTE controller is the ideal solution for anyone who wants reliable and simple remote device control. Its application is wide - from households to industrial facilities - and thanks to its operation via the GSM network, it works always and everywhere there is a mobile signal.

If you are looking for a practical way to improve comfort, safety and efficiency in your space, GSM 4G LTE Controller is a solution that will provide you with secure control and complete flexibility.

Frequently Asked Questions (FAQ)

1. Does the GSM 4G LTE controller work without internet?
Yes. The device uses the GSM network and functions via SMS messages or calls, so it does not need the Internet or Wi-Fi.

2. How many users can use the device?
Supports up to 200 users and up 20 administrators, which makes it suitable for both private and business buildings.

3. Can I open the gate by calling only?
Yes. When you call the SIM card number in the controller, the device automatically rejects the call (at no cost) and activates a relay that opens the gate or ramp.

4. What devices can I connect to the controller?
You can connect gates, ramps, pumps, lighting and other electrical devices up to 250VAC / 30VDC - 5A per relay to the controller.

5. Can the device send a notification when the sensor is activated?
Yes. You can connect sensors (eg alarm, switch, detector) to two digital inputs, and the controller will send an SMS message or make a call to the defined number.
