New improved version with longer time settings, step direction control and active output selection.
This module has 8 relay outputs that operate sequentially with a choice of Manual or Automatic triggering modes. The next relay activates as the previous relay turns off and when the last one has activated, the process will start again from the first relay.
Onboard DIP switches are used to set the time scale, number of active channels (from all 8 to just 1) and step direction.
In Manual mode the step sequence is advanced by closing the INC INPUT (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 1 second and 100 minutes using a scale switch and two onboard trimmers (coarse and fine).
RESET INPUT (contact closure operation): turns the active relay off when closed and restarts the sequence from Relay 1 when running forward and Relay 7 when running backwards. In Manual Mode, all relays remain off until a new input is received. In Auto Mode it will automatically restart.
PAUSE INPUT (contact closure operation): holds current relay when closed and resumes operation when opened.
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 note that the video shows the older version of this product that worked slightly differently.Specifications
