The SCD Irrigation Controllers were designed for the landscape industry. These controllers were first installed on the freeways of California in 1981. The SM (Seconds/Minutes) option was added to the SCD controllers specifically for greenhouses.

SCD controllers up to 16 stations are constructed with one panel. SCD controllers from 24 to 32 stations are constructed with two control panels in one enclosure.

• SC8DSM.........8 outputs + Master Valve
• SC12DSM......12 outputs + Master Valve
• SC16DSM......16 outputs + Master Valve
• SC24DSM......24 outputs + Master Valve
• SC32DSM......32 outputs + Master Valve

• All programming visible on face of controller. No KEYPAD or HIDDEN MEMORY. See the photo of the controller. The SCD controllers are so easy to program that persons who do NOT speak English can still easily be trained to set the irrigation schedule.
• 2 programs so that one irrigation schedule may be set to run on different days than the other program. For example, one program may run Monday, Wednesday and Friday while the other program may be set to run every day of the week. Any of the outputs may be assigned to either program.
• Each program may be set to start every hour of the day....up to 24 start-times in each program.
• Each each program may be set to repeat cycle the outputs of the controller from 1 to 15 times with each of the 24 start-times.
• The Run-Time for each output may set in 1 minute increments from 1 to 63 minutes, or in 1 second increments from 1 to 63 seconds.
• Pump-Start/Master-Valve output will activate whenever any of the valve outputs are activated.
• SCD controllers will deliver 24VAC @ 40VA through 1 or several outputs.
