4G LTE SMS Controller with Relay Outputs
The KTA-397 is a 4G LTE SMS controller designed for remote monitoring and control of industrial equipment - without needing an internet connection, app, or laptop. Simply send a text message from your mobile phone to switch relay outputs on or off, and receive automatic SMS alerts when inputs change state.
Built for Australian conditions, the KTA-397 connects to any 4G network via a standard Micro SIM. It comes with a magnetic base antenna and operates on a wide 9–36VDC supply, making it suitable for solar, battery, and mains-powered installations.
HOW IT WORKS
Configure up to 10 phone numbers to receive alerts. When a digital input changes state - such as a float switch triggering on a tank - the KTA-397 immediately sends an SMS to your nominated contacts. To control equipment, send a simple plain-text command like "Pump ON" or "Pump OFF".

• Remote pump control on farms, irrigation systems, and water tanks
