Siemens DDC R540-110N Control
The Siemens DDC R540-110N is a high-performance Terminal Equipment Controller (TEC) engineered for precise Direct Digital Control of HVAC terminal units, including fan coil units, induction units, and pressure-dependent boxes. This refurbished controller is a field-proven solution for contractors maintaining Siemens APOGEE or TALON building automation systems. It features six digital outputs and operates on 24VAC 50/60Hz power, providing a robust hardware platform for heating, cooling, and fan speed modulation. The 540-110N utilizes advanced PID algorithms to ensure stable temperature regulation while minimizing valve and actuator wear. Since it stores setpoints in EEPROM, the unit requires no battery backup and resumes operation immediately after a power failure. This module supports RS-485 communication over a Floor Level Network (FLN) trunk, allowing for seamless integration into existing building management systems (BMS) for centralized monitoring and energy management.
Key Benefits:- Direct Digital Control (DDC) for precise temperature and fan speed management.
- Compatible with Siemens APOGEE and TALON systems via FLN communication.
- Integrated EEPROM ensures retention of control logic without 10-year battery maintenance.
- Optimized for fan coil units, unit ventilators, and heat pump applications.
- Plenum-rated construction for safe installation in ceiling spaces and mechanical enclosures.
Which HVAC applications is this controller pre-programmed for?
The R540-110N is typically loaded with applications for unit conditioners, such as 2-pipe or 4-pipe fan coils and induction units. Always verify the application number matches your field requirements.
What is the power consumption of this module?
The unit consumes approximately 3 VA at 24VAC, making it efficient for multi-controller system architectures.
Does this unit require an external room sensor?
Yes, it features a quick-connect RJ-11 jack for Siemens room temperature sensors, which provide the primary feedback for the control loops.
