The RTU5024 GSM gate opener allows users to remotely control gates, doors, and other equipment by making a free phone call from an authorized number. It uses the phone’s caller ID for identification, ignoring unknown callers, and can be managed by SMS text commands to add or remove users, with up to 200 authorized numbers possible. The device features a relay with a programmable on/off time and works with a standard 2G SIM card on a global GSM network.
