As a member of the DHx21B series ("DH" stands for Distributed Hardware), the DHE21B supports distributed installation and can be deployed directly next to equipment rather than in a centralized control cabinet, reducing wiring costs and accommodating flexible production line layouts.

Integrating logic control, motion control, and communication functions, it meets basic automation needs without the need for additional expansion modules. Its compact size saves installation space, making it particularly suitable for space-constrained field environments.

Deeply compatible with compatible servo drives, inverters (such as the MDX series), and motors, it supports unified parameter configuration and diagnostic protocols, simplifying the commissioning and maintenance of the entire drive system.

Supports basic logic control (similar to PLC ladder diagram programming) and simple motion control functions, such as point control and speed synchronization control. It can drive 1-4 axis servo or variable frequency systems, making it suitable for small and medium-sized motion control scenarios (such as small conveyor lines and packaging machines).

Standardly supports mainstream industrial Ethernet protocols such as EtherNet/IP and Profinet, and also supports the specific MOVILINK® DDP protocol, enabling high-speed data exchange with the drive (up to 1ms cycle time), ensuring real-time control instructions.

Equipped with comprehensive fault diagnostics, it monitors the operating status of itself and connected drives (such as overcurrent and communication interruption) in real time, and indicates the fault type through indicators or a host computer. It also supports safety signal access, enabling linkage to implement basic safety logic such as emergency stop and safety door functions.

Equipped with 8-16 digital inputs (PNP/NPN switchable) and 4-8 digital outputs (transistor type), these devices can directly connect to peripheral devices such as sensors, buttons, and solenoid valves, meeting basic signal acquisition and control needs.

Some models include 1-2 analog inputs (0-10V/4-20mA) for receiving analog signals from potentiometers, pressure sensors, and other devices, suitable for scenarios requiring continuous adjustment (such as tension control).

Supports bus expansion with remote I/O modules or encoder signals (such as incremental encoders) for precise feedback and closed-loop control of motor position.

For example, packaging machine sealing and feed axis control, and workstation synchronization in small assembly lines.

For example, zoned conveyor control in logistics sorting lines and travel axis drives in warehouse AGVs. Compatible scenarios: For example, when combined with the MDX61B servo drive, a complete motion control solution for a single device can be achieved.
