TDG140 – 2G GSM remote control via SMS and DTMF, 2 relays and 2 inputs

TDG140 – GSM remote control with 2 relays and 2 inputs

The TDG140 allows you to remotely control two relay outputs and monitor the status of two opto-isolated alarm inputs. It is suitable for monitoring burglar alarm systems for buildings and vehicles and for controlling pumps, irrigation, heating, air conditioning, and industrial systems via compatible circuits.

Commands and notifications

• Control via SMS or DTMF: activate and deactivate relays, trigger timed pulses, and check the status of inputs and outputs. DTMF tones are sent during a voice call.
• SMS configuration: management of up to 8 numbers, alarm notifications per recipient via SMS or ring, setting of input conditions and intervention times and customization of alarm messages.
• Call access: filtering of stored numbers and configurable password requirements. The DTMF pulse duration can be set separately for each relay.
• Power Management: Configurable SMS start-up and reset of relay status after a power outage. SMS power failure and power restoration alerts require firmware 4.0 or later and the optional FT1320M UPS.

The module can also be configured locally from a PC using the TDG configurator and the optional FT782M USB interface. For command syntax and configuration instructions, see the TDG140 manual.
