Signal SD-DC-3B 3-Way Latching DataCoil with S402 Base & LED Status Indicators

Upgrade any standard hydraulic valve into a smart, two-wire compatible field device with the Signal SD-DC-3B 3-Way Latching DataCoil™, designed for seamless integration with SDS Series Two-Wire Irrigation Controllers. Fitted with a rugged S402 base and dual LED indicators, this coil simplifies installation, improves visibility, and increases system reliability.

Using patented two-wire communication, the DataCoil™ reports its operational status back to the controller every 3 seconds — enabling real-time diagnostics of valve health, wiring integrity, and system performance. Its LED status lights are housed under a special diffuser lens, allowing clear visibility from a standing position.

Built to industry-standard dimensions and rated to 10 bar, the SD-DC-3B is suitable for a wide range of hydraulic valve types across both landscape and agricultural applications.
