SAN Telequip’s Smart Alert Gateways are cellular-based (2G/4G) embedded systems designed for remote monitoring and predictive maintenance, delivering real-time alerts via SMS, Email, and Voice messages upon sensing process condition changes. These rugged DIN-rail units feature a combination of Analog (4-20mA) and Digital Inputs, as well as Digital Outputs and an RS485 Modbus RTU Master port to extract alarm conditions from field devices. They operate over a wide temperature range of -35°C to 80°C, supporting up to 10 reporting numbers and featuring a built-in RTC for time-stamped alerts.
