CompactLogix Controller → 1769-OB32T Output Module → DC Output Signal → Field Devices
The main functions include:
- Receiving control commands from the processor
- Switching DC output channels
- Controlling external devices
- Providing electrical isolation between control logic and field equipment
- Monitoring output status
During operation:
- The controller processes machine logic
- Output commands are sent to the 1769-OB32T
- The module activates selected output points
- Connected devices receive electrical signals
- Industrial equipment performs the required operation
This process enables accurate and reliable machine control.
