Designed for either liquid or granular single-product automatic control. Console has nonvolatile memory, printer output, and 2-way communication for uploading and downloading GPS information. One simple programming step allows you to choose between liquid or granular control features.

Liquid control features are similar to the SCS 440. Granular features include off rate, flow, left and right shaft, and bin level alarms, fan RPM, and spreader constant (density).

Notes: The 661 can control up to 10 booms. As the 660/661 does not have switches it requires an additional boom switch console. View "Related Parts and Products" for Raven flowmeters, valves and SCS 660 parts. Call for 661 cable part numbers.
