Time delay versions offer built-in control capability with settings for normal operation, on delay, off delay, on-off delay, or one-shot delay. The timing range can be adjusted from 0.6 to 16 seconds for each.

Each model incorporates a universal voltage design to allow use with 16 to 240V AC or DC power. Wiring, sensitivity adjustment, timing adjustment and light/dark selection are all easily accessed by removing a sealed cover. A unique guard shields the user from electrical connections when making these adjustments, and flips up to allow access to the terminal screws. The cover fastening screw is held captive to prevent loss.
