How far away can I activate a DC solenoid

While closer is always better. The HRC-990 or CMS can generally be between 75 and 100 feet from DC latching solenoid. Wire condition, wire thickness, wire material, and electrical connections will all affect the maximum distance between the controller and the valve.

13V DC Power Drop / Max Cable Distance Chart #

The below DC voltage drop cable distance chart works as follows. The left column notes the amount of power that the device you are powering requires. The Hydro-Rain 13 VDC Latching Solenoid has an operating current of about 1 amp.

For example, say you want to mount the HRC-990 about 75-feet away from the solenoids. Using 18-gauge wire, you can run your wires about 86 feet.
