GSM-R4-DIN

The GSM rele4– DIN is designed to be mounted on a DIN rail into a switchboard. GSM rele4 can control two independent electrical circuits in a building e.g. circuit of an accumulator stove and circuit for garage gate control. The control is made via SMS messages or by ringing. After installation into an electrical box insert a SIM card of any GSM operator and the device is ready to operate.

GSM rele4 has 2 galvanically isolated logical outputs with a semiconductor switch, which can control directly low power circuits up to 230 VAC/90 mA. It’s possible to directly control e.g. a thermoregulator circuit of a gas boiler or a coil of one phase contactor 230 VAC. The contact of this contactor can control either one phase high power appliance (e.g. electrical radiator) or a coil of three phase contactor of an accumulation stove.

GSM rele4 has also 2 analog inputs for temperature measuring and 2 logical inputs which can be activated by a contact from 4V power provided by GSM RELAY 3 or by an external voltage 3 to 30V DC. GSM rele4 has built in automatic regulator which uses analog inputs from temperature sensors to maintain preset temperature. The temperature on sensors can be readout via SMS. There is an internal built in Li-Ion accumulator which enables to send an SMS in case of a power failure and to restore the output status after a power failure. It’s also possible to monitor the status of inputs and temperatures via SMS during 230 V power failure.

Usage

• remote control of electrical appliances
• Event SMS – e.g. 230 VAC failure

Advantages

• simple installation
• easy to  use

Datalogger

The GSM rele4 has a new capability to log periodically temperature valus, changes/events on inputs and outputs, SMS commands, etc. onto MicroSD card. The logged data can be downloaded remotely via GPRS connection or localy by inserting the MicroSD card into the PC. The content of logged data depends on the the configuration setting of the GSM rele4.

Note: The data logger is not available on GSM-R4-DINB as a standard, but there is possibility to buy a license for data logging additionally.

Variants

*1) It’s possible to buy a license for MicroSD card and for data logging.
