Information About 540-103N
The 540-103N is part of the Siemens APOGEE FLN TEC controller family and is intended for constant-volume HVAC control. The controller operates from a 24 VAC supply and connects to a field panel through a Floor Level Network (FLN) trunk. It provides six digital outputs using optically isolated solid-state switches rated at up to 0.5 A, supporting damper actuators and other compatible HVAC equipment. Depending on the application, the controller can support cooling-only, electric-reheat, or hot-water-reheat configurations.
Key Features:
- Constant Volume Control: Provides direct digital control for pressure-independent constant-volume HVAC applications.
- FLN Communication: Connects to a Siemens field panel through a Floor Level Network trunk.
- Standalone Operation: Can operate independently as a local DDC room controller.
- Six Digital Outputs: Provides six 24 VAC optically isolated solid-state outputs.
- Damper Control: Supports connection to compatible damper actuators for airflow regulation.
- Reheat Applications: Supports compatible electric or hot-water reheat configurations.
- 24 VAC Operation: Uses a low-voltage 24 VAC power supply for controller operation.
- Flexible Applications: Supports Siemens applications 2030, 2032, and 2033.
The 540-103N delivers reliable digital HVAC control and FLN communication for constant-volume air-handling applications.
