0-10V Fan Speed Controller

FSCD Series Digital Single-Phase Fan Speed Controllers | Flexible Integration, Powerful Performance

Looking for advanced fan speed control compatible with building automation systems? The FSCD Series Digital Single-Phase Fan Speed Controllers are engineered for precise proportional control of single-phase fan motors, delivering high performance and seamless integration into modern HVAC systems. With a maximum load capacity of 10 Amps, the FSCD series ensures reliable operation for large resistive and inductive loads.

Two Model Options for Automation Flexibility

The FSCD series includes two models tailored to different control infrastructures:

• FSCD.1PH.A.10A – Operates with a 0–10V analog control signal. It adjusts fan speed proportionally based on signals received from external controllers. Widely used in air handling units, cooling systems, and heat recovery ventilation (HRV) equipment.


• FSCD.1PH.M.10A – Communicates via RS485 Modbus RTU protocol, enabling direct integration with centralized automation systems. It supports advanced monitoring and control functions and is fully compatible with SCADA platforms.

Key Features & Benefits

• On-Device Trimpots – Allows easy field adjustment of minimum/maximum fan speeds and acceleration time, offering both remote and local configuration flexibility


• Microcontroller-Based Proportional Output – Delivers accurate and energy-efficient fan speed control


• Robust Design – Built for long-term reliability in industrial and commercial HVAC environments


• Automation-Ready – Perfect for modern building automation, compatible with both analog and digital infrastructures


• Flexible Installation – Suitable for wall or panel mounting in control systems

Whether you require analog control or full Modbus RTU communication, the FSCD series provides a scalable, high-performance solution for demanding ventilation and climate control applications.
