### 4. Analog Input Logic Functions (IB/IC used as discrete triggers)
|
||
|
||
Seven comparison functions can be performed on the analog inputs IB and IC to generate discrete contact outputs A1:
|
||
- **Analog 1:** A1 closes when IB **≤ reference voltage**
|
||
- **Analog 2:** A1 closes when IB **≥ reference voltage**
|
||
- **Analog 3:** A1 closes when IC **≤ reference voltage**
|
||
- **Analog 4:** A1 closes when IC **≥ reference voltage**
|
||
- **Analog 5:** A1 closes when IB **≤ IC**
|
||
- **Analog 6:** A1 closes when IB **≥ IC**
|
||
- **Analog 7:** A1 closes when IB is **within the window IC−H to IC+H** (hysteresis band)
