Cebek I-55 is a 8 output sequential controller. The 8 relays will be operated one at a time and in a set set sequence. They can be activated by an external contact or run from the internal clock. The on board clock can be adjusted by the PCB mounted preset potentiometer between 0.3 and 10 seconds. The I-55 module includes the connection for a reset switch, which will return the controller to the first relay. Each relay has an LED to indicate the condition of the output.
