GSM control combines SMS text alarm messages with Caller-ID secure remotely controlled outputs in one low-cost package
The GSM Control Din rail device combines the ability to send up to four text messages from a remote machine or process using a simple volt-free input.
The device will also respond by switching either or both of the 6A relay outputs by just ringing the unit of sending a SMS text string.
The GSM Control prevents unauthorised usage by checking the callers ID in the internal phonebook.
The GSM Control also provides a free ringback to the user to acknowledge the action has been performed - ideal for remote sites.
Two versions are available: one with a built in antenna and one with external antenna.
All devices are dual band allowing low cost pay-as-you-go SIMs to be used from all the major networks in the UK and internationally.
Existing applications include remote pumping and irrigation sites, water treatment, process machines, coin-op vending machines, entry systems etc.
