DGSM-2A UNIVERSAL GSM MODULE
2 RELAY OUTPUTS + 2 CONFIGURABLE INPUTS
GUARANTEED COMPATIBILITY WITH THE FOLLOWING OPERATORS:
TIM – WIND – VODAFONE
Professional, universal GSM module designed for remote control of gates, garage doors, automation systems, alarm systems, boilers and many other applications.
Thanks to its 2 relay outputs with volt-free contacts and 2 configurable inputs, the module makes it easy and quick to set up control and signalling systems via the GSM network.
Configuration is easily carried out using simple SMS commands, with no need for dedicated software.
Mod. GSM-C
SKU: 1434/2
KEY FEATURES
Universal GSM module for automation systems, alarms and remote control.
Universal 12/24 V power supply, both AC and DC.
2 relay outputs with voltage-free contacts, independently configurable.
Relay outputs rated for a maximum of 30 Vdc / 0,5 A.
Outputs configurable in timed or bistable mode.
2 configurable alarm inputs for connection to voltage-free contacts.
Inputs configurable as NO (normally open) or NC (normally closed).
Gate opener function via phone call.
Alarm function with SMS notification and alert call.
Configure inputs, outputs, and authorized numbers via SMS.
Dedicated LEDs indicate the status of the inputs.
Red and green LEDs indicate the module's operating status.
Automatic periodic restart (keep-alive) function to prevent possible SIM card/module lockups.
GATE OPENER FUNCTION
The module can be used as a GSM gate opener.
When it receives a call/ring from a telephone number previously saved in the SIM card phonebook, the module activates output RL1.
The factory configuration is as follows:
RL1: pulse operation
Pulse duration: 3 seconds
The command can therefore be used to control, for example, automatic gates, garage doors, electric locks and other compatible automation systems.
ALARM FUNCTION
The two inputs can be connected to devices with a volt-free contact, such as:
sensors;
magnetic contacts;
pressure switches;
safety devices;
alarm systems;
contacts from automation systems;
other devices with a contact output.
When an input configured as an alarm is triggered, the module can:
send an alarm SMS to the enabled numbers;
make an immediate alert call.
Factory input configuration
IN1: normally open (NO)
IN2: normally closed (NC)
Input debounce: 1 second
The inputs can be configured using specific SMS commands.
CONFIGURABLE RELAY OUTPUTS
The module has 2 relay outputs, which can be used to control external devices via a volt-free contact.
The outputs can be configured according to the intended application, with the following operating modes:
impulsivo/temporizzato;
bistabile.
Factory settings
RL1: pulse, 3-second duration
RL2: bistable
Maximum relay contact rating: 30 Vdc / 0,5 A.
SMS CONFIGURATION
The module is easy to configure using SMS commands.
The following can be managed and configured:
authorized phone numbers;
IN1 and IN2 inputs;
input operating mode;
RL1 and RL2 outputs;
pulse or bistable mode;
output timing;
control and alarm functions.
This solution allows the module to be adapted to numerous requirements without using software or a dedicated programmer.
