This module has 8 relay outputs that operate sequentially with a choice of Manual or Automatic triggering modes. As the next relay activates, the previous relay will turn off and when the last one has activated, the process will start again from the first relay.

MANUAL Mode:
In Manual mode the relays are triggered by external impulses (a simple volt-free contact closure).The sequence advances by one step only regardless of the input duration. The module will advance to the next relay and turn off the previous relay each time a fresh trigger input is received.

AUTOMATIC Mode (demonstrated in video):
In Automatic mode the module automatically and continuously steps through the relays in sequence (1, 2, 3, 4, 5, 6, 7, 8, 1, 2, etc.) when power is applied. The "step" time period can be adjusted between about 0.3 and 10 seconds.

A Reset input (contact closure operation) returns the current sequence to the Relay 1 position. In Automatic Mode, it will be held at this position until the Reset input is released.

The module has no memory function and will always start from the Relay 1 position when powered-up or reset.

The board has protection against inverse polarity, indicator output LEDs for each relay and screw terminals for connections.

Please see Order Code CI005 for a 4 channel version of this product and CI057 for a more flexible and expandable version.
