Each BEC-500 occupies 6 DIN rail modules (approx. 105mm width). Follow this sequence:

The BECSys5 architecture is modular, but the core server or industrial PC must meet these minimum specs:

| Terminal Block | Signal Type | Max Wire Gauge | Notes | |----------------|-------------|----------------|-------| | PWR | 24VAC/DC | 14 AWG | Use twisted pair, fuse at 3A | | GND | Earth | 14 AWG | Connect to panel ground bus | | AI1–AI8 | 0–10V, 4–20mA | 18 AWG | Shielded cable, ground shield at controller end | | DI1–DI12 | Dry contact | 18 AWG | Use 12V internal wetting (configurable) | | AO1–AO4 | 0–10V | 18 AWG | Max load 10mA per output | | DO1–DO8 | 24VAC/DC @ 2A | 16 AWG | Flyback diode required for inductive loads |

Ensure the water is balanced manually (using a DPD test kit) before syncing the controller’s digital reading with your manual test results. 4. Advanced Features & Communication
