DRM

DRM is a digital multi functional controller designed to control the speed of high speed, three-phase, asynchronous motors installed on axial, radial or centrifugal fans in HVAC/R and industrial applications. Control is based on phase-cut control balanced with the main supply, which enables accurate, dynamic control, optimizing energy efficiency and reducing electrical and mechanical wear and tear of the components.

Designed to function in slave mode, DRM has two analog inputs compatible with 4-20 mA and 0-10 Vdc signals, and one independent PWM input which means it can be easily integrated with digital control systems. This configuration makes the device suitable for remote commands in accordance with heat exchange requirements and it can be easily integrated into existing system modes.

The controller supports advanced functions like remote Start/Stop, reverse function and reading the TK overheat contact thereby helping to improve safety and operating reliability. The0-10 V output allows slave devices to be directly driven, facilitating the synchronized management of a number of elements in the HVAC system.

The DRM interface features a backlit LCD display with 2 lines and 16 characters, for a user-friendly interface for local programming of the device, and permits, if necessary, transformation of the system into master units.

Thanks to the protection against power surges, overloading or heat anomalies, DRM is suitable for installation in complex industrial environments. The IP20 version is available for assembly on electric panels and the IP55 version is available for applications in challenging environments.

DRM is a robust, versatile and complete solution to control ventilation in chillers, dry coolers and industrial HVAC systems, guaranteeing optimized performance and maximum operating efficiency.

• Analog inputs (slave): 2 inputs compatible with 0-10 Vdc and 4-20 mA
• signals PWM input: 1 independent input for digital command
• Auxiliary on-off contacts: Start/Stop functions, reversal of function, TK reading
• Auxiliary output: 0-10 V signal to drive slave devices
