The SDS-50 is a new generation of irrigation controller with the latest in electronic and communication technology.
As powerful as this compact controller is, it can be serviced on a DIY level due to the plug-in modules for both the microcontroller and output stages.
The controller consists of a motherboard, plug-in logic board, plug-in output module and plug-in keypad assembly. LEDs on each module indicate if faulty and in need of replacement.
All three boards are available seperately or together as a kit.
