8-Zone Automatic Sequencer for Pool Cleaning

Modular automatic sequencer for DIN rail mounting, designed to precisely manage the sequential activation and deactivation of eight outputs for Net'n'Clean-type pool floor cleaning systems. Its architecture, based on a master/slave system, allows the main module to receive the trigger signal and control the sequence rhythm. In extended configurations, the complementary module continues the activation after the master cycle, allowing sequences of up to 16 outputs (requires two devices). Operation is based on a programmable timer configured via DIP switches. A first group defines the device role (master or slave) for coordinated integration. A second group selects the activation interval for each output (1, 2, 5, or 10 minutes), adjusting the cycle as needed. Finally, a third set of switches uses three-bit binary coding to define the number of outputs, providing flexibility for specific application requirements.
