120V Unloader Timer, 20m/15s
120V solid state timer used to control automatic drain systems, Upon initial power, current is made available to the solenoid valve on the drain system, for a period of 20 minutes (closed time). After this time the current is interrupted for 15 seconds (drain time). Repeats until power is cut-off at which time the drain opens again. This time period is suitable for Worthington, Ingersoll-Rand and many other american compressors that require a 15 second drain period. Power should be same as solenoid voltage.
