STD32 – GSM Telemetry Device with SMS, E-mail & Remote Relay Control

The STD32 is a stand-alone telemetry device that provides alerts via SMS or e-mail and remote control of output relays via a call, text SMS or web interface.
It has two optocoupler inputs for monitoring states (alarm, fault, dry-contact, etc.). In the event of an alarm, the STD32 automatically sends an SMS or e-mail to up to 5 recipients.
The two relay outputs can be activated by:
- a free call (CLIP, with no call charge),
- sending an SMS with commands,
- or via web browser, when there is GPRS access.
Configuring the STD32 telemetry unit is extremely simple: the basic setup is done with a single phone call to the device. All the additional configuration can be done by:
- sending an SMS to the device, or
- via web-browser interface (when the SIM has data access).
Key Features
- Stand-alone stand-alone telemetry device.
- Quad-band GSM technology for worldwide compatibility.
- 2 relay outputs for load control (up to 6A / 230Vac each).
- 2 digital inputs with an alarm function (optocoupler inputs).
- Two-way communication for controlling outputs and reading status (via SMS or web browser).
- Alarm sending by SMS or e-mail to up to 5 programmed recipients.
- Indicator LEDs for the status of the inputs, outputs and the GSM network.
- Ready to use thanks to a standard configuration – a single call from a mobile is enough for the initial activation.
- Expert configuration for personalisation settings (via SMS or web browser).
