Product Description:
The DMC-50720-EXT-24V is a motion-control module from Danaher that belongs to the DMC Motion Controllers series. It interfaces between higher-level PLCs and servo drives, issuing position and velocity commands while monitoring feedback for closed-loop automation tasks such as pick-and-place gantries or conveyor indexing. By integrating analog, digital, and power stages in one unit, the controller streamlines panel layouts and reduces wiring in multi-axis industrial systems.
The controller samples incoming position or process feedback with 14-bit analog input resolution and generates drive commands through a 12-bit analog output channel. The controller supplies servomotors with 7 A continuously and can reach 20 A during short acceleration bursts. Efficiency remains at 95% under rated load, helping limit heat within the enclosure. Six digital outputs are available, with each output sinking or sourcing up to 100 mA for relays or indicators. Velocity regulation benefits from an open-loop bandwidth of 2 kHz, allowing the controller to follow dynamic motion profiles. A switching frequency of 4 kHz modulates the power stage, and motors must have an inductance of at least 8 mH to keep current ripple within safe limits.
System protection is provided by an external 1.5 A time-delay fuse on the supply line. The control electronics operate from a 24 VDC logic rail that draws up to 0.7 A during peak activity. The module encloses its circuitry in an IP20 housing, so it must be mounted inside a cabinet with controlled airflow. Its RMS output is 4.5 A at 40 °C, which indicates the sustained current available at that operating temperature. A minimum speed ratio of 1:9000 supports fine motion scaling across a broad operating range. These operating values help determine the appropriate motor, power supply, cabinet ventilation, and protective components for the installation.
