Overview
The Beck DCM-3 22-5014-59 is a microprocessor-based interface PCB designed for Beck electric actuators and damper control systems. This third-generation Digital Control Module (DCM-3) delivers precision modulating control while maintaining full backward compatibility with original DCM and DCM-2 boards. The 22-5014-59 is standard equipment on all new Beck Group 11, 14, 29, 42, and 75 actuators built after July 2016, and serves as a direct replacement board for retrofit applications.
Key Features
- Direct replacement for original DCM and DCM-2 modules with identical mounting and connections
- Accepts both 4–20 mA and 1–5 V demand signal inputs
- Operates reliably across –40°F to +185°F temperature range
- Provides 0.1% span repeatability and precision position control
- Three configuration interfaces: pushbutton, HART communications, and DB9 Serial Port
- Fast setup and calibration without mechanical adjustments
Technical Specifications
- Input Signal: 4–20 mA or 1–5 V analog demand signal
- Operating Temperature: –40°F to +185°F (–40°C to +85°C)
- Position Control Repeatability: 0.1% of span
- Communication Interfaces: HART protocol (Rev. 5), DB9 Serial Port, Pushbutton interface

- Manufacturer: Harold Beck & Sons, Inc. (Beck)
Typical Applications
The Beck DCM-3 22-5014-59 is widely used in industrial process control for damper and valve position control, including HVAC systems, process cooling systems, and fluid coupling applications requiring up to 1,800 lb-ft torque. The board is also installed in Group 14 linear actuators for proportional flow control in industrial automation systems. HART communications capability enables integration with asset management and field device diagnostics platforms.
