Description

The ACC-24E2A is a versatile, multi-axis digital input/output (I/O) expansion board for Delta Tau’s PMAC (Programmable Multi-Axis Controller) family. This board provides a significant number of configurable digital input and output channels, enabling PMAC controllers to interface with a wide range of external sensors, actuators, and other digital devices in industrial automation systems.

Application Scenarios

Consider a complex automated packaging line with numerous sensors detecting product presence, limit switches indicating mechanical positions, and solenoid valves controlling pneumatic actuators. Connecting all these discrete signals directly to the PMAC CPU might exceed its built-in I/O capacity and complicate wiring. The ACC-24E2A serves as an efficient solution in such scenarios. By providing a substantial expansion of digital I/O points, the ACC-24E2A allows the PMAC controller to seamlessly monitor the status of various sensors, control the activation of actuators in a synchronized manner, and manage the overall sequencing of the packaging process. This centralized and expanded I/O capability simplifies system design, enhances control flexibility, and improves the reliability of the automated line.

Application Cases and Industry Value

In a modern automated warehouse, efficient material handling relies on the coordinated operation of numerous conveyors, diverters, and sorting mechanisms. These systems utilize a multitude of sensors (e.g., photoelectric sensors, proximity switches) to track the movement of goods and various actuators (e.g., pneumatic cylinders, motor starters) to control the flow. The Delta Tau ACC-24E2A serves as a crucial interface in such applications. By providing a large number of isolated digital I/O points, the ACC-24E2A enables the PMAC controller to monitor the real-time status of all the sensors and precisely control the activation of the actuators, ensuring the smooth and accurate movement of materials throughout the warehouse. This expanded and reliable I/O capability directly contributes to increased throughput, reduced errors, and optimized logistics within the automated warehouse environment.
