Function and Working Principle
The 900B08-0101 module functions as a final analog signal output interface between the control system and field devices.
It is responsible for:
- Receiving control signals from the HC900 controller
- Converting digital values into proportional analog current outputs
- Driving field actuators such as valves and dampers
- Maintaining stable real-time process control signals
- Providing safe fallback behavior in case of communication loss
Each channel corresponds to a dedicated process control loop output.
