Versatile Analog Processing with the DAU 108

This analog module provides eight universal channels for flexible signal acquisition and generation. The DAU 108 handles both input and output functions, adapting to various process requirements. Each channel independently configures for voltage or current signals. The module operates within the Compact 800 series architecture for distributed control systems. It also offers 12-bit resolution for accurate data conversion and control. The DAU 108 includes a status LED array for instant channel diagnostics and fault reporting.

Technical Specifications and Physical Dimensions

The DAU 108 accepts input ranges of 0–10 V and 0–20 mA for versatile sensor compatibility. For outputs, it generates 0–10 V signals, enabling effective actuator control. Each channel provides a maximum common-mode voltage of 30 V for robust protection. The module measures 44 mm in width, 127 mm in height, and 123 mm in depth. It weighs approximately 0.6 kg, suitable for installation in Compact 800 racks. Furthermore, the unit draws 140 mA from the +5 V bus and 30 mA from the +24 V supply. Its operating temperature spans 0 °C to 55 °C for consistent industrial performance.

Configuration and Application Guidance

This module serves dual roles in both monitoring and control applications. First, set the channel jumpers to match your selected input or output mode. Then, wire the field devices to the removable terminal blocks using twisted-pair cables. For current inputs, remember to install the provided 250 Ω resistors across the terminals. For output applications, the DAU 108 drives actuators through the 0–10 V signals. Additionally, perform a calibration routine using the configuration software for optimal accuracy. The DAU 108 complies with IEC 61131-2 standards for reliable operation in demanding environments.
