The Signal SD-LB Plug-In Controller Logic Boards are genuine replacement modules designed for Signal SDS Series Two-Wire Irrigation Controllers. Acting as the logic and communication core of the controller, these boards manage irrigation program execution, two-wire communications, SignalCloud™ connectivity, SDS-LINK app functions, and overall controller operation. The modular plug-in design allows faulty logic boards to be identified and replaced quickly in the field without returning the complete controller for servicing, helping reduce downtime and maintenance costs across commercial, landscape, and agricultural irrigation systems.
Suitable Applications
- Replacement of faulty or damaged SDS controller logic boards
- On-site repairs of Signal SDS Series irrigation controllers
- Commercial landscape irrigation systems
- Agricultural and farm irrigation systems
- Two-wire irrigation controller maintenance
- Preventative maintenance spare-part inventories
- Contractor and irrigation service vehicles
- Critical irrigation sites requiring rapid controller restoration
- SDS-50, SDS-75, and SDS-100 controller servicing

Benefits
- Reduced Controller Downtime: A faulty logic board can be replaced individually, allowing the irrigation controller to be returned to service without replacing or transporting the complete unit.
- Lower Repair Costs: Modular servicing allows the affected electronic component to be replaced rather than purchasing an entirely new controller.
- Fast Field Diagnosis: Integrated LED status indicators help technicians identify controller faults and determine which module requires attention.
- Simple On-Site Servicing: Plug-in board construction allows maintenance to be completed quickly using the controller’s existing modular architecture.
- Maintains System Functionality: Correct replacement boards restore the controller’s programming, two-wire communication, cloud connectivity, and mobile management capabilities.
- Ideal as a Critical Spare: Keeping the correct logic board on hand can significantly reduce downtime at commercial, agricultural, or other irrigation sites where continuous controller availability is important.
