The **ABM2-R6RA2-M2** is a modular electronic component commonly used in industrial automation, specifically within the realm of fieldbus communication and decentralized I/O systems. It is most frequently associated with **Bihl+Wiedemann** AS-Interface (AS-i) modules. --- ### 1. General Specifications This part functions as an AS-i motor module designed to control motorized rollers (MDR) or similar actuators. | Feature | Description | | :--- | :--- | | **Interface** | AS-Interface (AS-i) 3.0 | | **Housing Type** | Sub-structure module / Circuit board module | | **Inputs** | Typically 2 Digital Inputs (for sensors/feedback) | | **Outputs** | Typically 2 Digital Outputs (for motor control) | | **Protection Rating** | IP20 (intended for installation in terminal boxes or cable ducts) | --- ### 2. Breakdown of the Part Number Components While manufacturers use specific internal codes, the nomenclature for this series generally follows this logic: * **ABM:** AS-i Board Module (OEM/Internal PCB style). * **2:** Often refers to the AS-i version or the number of connected motors. * **R6:** Reference to the specific power/current rating or connector type (M12 vs. Terminals). * **M2:** Indicates the capability to control **2 Motors** (e.g., Interroll or Itoh Denki rollers). --- ### 3. Key Electronic Functions #### A. Motor Control The module provides the logic and power switching to manage the start/stop, direction, and speed (via frequency or preset signals) of motorized rollers. It is optimized for "Plug-and-Play" integration with conveyor systems. #### B. AS-Interface Communication It acts as a "Slave" on the AS-i network. It receives commands from the AS-i Master and sends back the status of connected sensors (e.g., photoeyes detecting a package) and the health status of the motors. #### C. Power Management * **AS-i Power:** Used for communication and low-power logic. * **AUX Power (24V DC):** Usually required to provide the high current necessary for the motors. The module handles the isolation between these two power circuits. --- ### 4. Technical Summary | Parameter | Typical Value | | :--- | :--- | | Operating Voltage | 18V - 31.6V (AS-i) | | Auxiliary Voltage | 24V DC (±15%) | | Connection | Spring-type terminals or Pin headers | | Operating Temp | -25°C to +70°C | ---
