AES Master-Slave Connection Kit for ELPRO S20/S40/S50 - 2783L

The AES Master-Slave Connection Kit allows dual ELPRO boards (S20/S40/S50) to communicate, synchronizing up to eight automatic or semi-automatic bollards across multi-entry systems. Only the Master unit is programmed; the Slave follows predefined timing logic, making setup and operation consistent across all posts. The kit enables shared accessories like LED lights, heaters, or photocells and avoids command overlap through priority logic. Preconfigured connectors and mounting hardware simplify installation, and the system supports pedestrian-only and group open/close commands via wired or wireless triggers.
