SED-30 (4G)
4G I/O  SMS Controller

The SED-30 is a fully programmable 4G SMS I/O controller for remote monitoring and control of virtually any device over the mobile network. Originally developed to help farmers remotely control irrigation pumps and machinery, it has since grown into a world-class, flexible SMS input/output controller used across countless applications.

The SED-30 reports input triggers and switches its onboard outputs entirely via SMS — giving you reliable remote control and monitoring anywhere there's 4G coverage. Use it for pumps, gates, doors, machinery, lighting, alarms, remote equipment and more. Australian designed, developed and supported by Sec-Eng Systems.
