The DELTA TAU ACC-68E is a versatile digital I/O interface board designed for industrial automation and motion control applications, primarily within the Delta Tau UMAC (Universal Motion and Automation Controller) system. It provides 24 isolated sinking digital inputs and 24 sinking digital outputs, making it suitable for handling a wide array of sensor and actuator signals in automated production lines, numerical control machine tools, and power system monitoring. The isolated inputs and self-protection features ensure robustness against electrical interference and safeguard connected equipment, crucial in industrial environments where electromagnetic noise is prevalent. Typical operating conditions range from -20°C to 60°C with relative humidity tolerance from 10% to 90%, supporting stable performance in varied industrial settings.
As a multifunctional digital I/O card, the DELTA TAU ACC-68E plays a critical role in monitoring inputs—such as start/stop commands, proximity sensors, and limit switches—and controlling outputs that drive motors, relays, and alarms. It is an essential building block in control system architectures requiring high signal density, fast response times at the millisecond level, and reliable, isolated signal paths to minimize downtime and maintenance. The compact design supports installation in modular racks alongside other Delta Tau control components, facilitating system scalability and integration.
Key technical features include its 24 inputs and 24 outputs all operating at 12-24 V DC with sinking current types, self-protection against overcurrent conditions, and terminal block or D-Sub 15 pin connection options. This hardware is optimized for rapid digital signal processing, allowing seamless real-time control in highly dynamic industrial settings. The module’s isolation and protective mechanisms enhance noise immunity and extend operational lifetime, critical for applications demanding long-term reliability and minimal maintenance interruptions.
