Cebek R-13 module is a night to day and day to night dimmer. You can adjust the time of the effect between 1 second through to 2 hours by means of a PCB mounted potentiometer and DIL switches. It has a rest function and the effect is activated by a change over switch. When used in conjunction with I-11 or I-111, it allows an automatic switching between the day and the night, with quiescent adjustable times. This module will not control inductive loads.
