Overview

The Woodward 9905-968 Analog Input Module is part of the LinkNet series, engineered for high-accuracy signal acquisition in harsh industrial settings. It features six isolated analog input channels, each capable of measuring 4–20 mA current signals, commonly used for sensors monitoring pressure, temperature, flow, and other process variables.

Moreover, the module supports LON (Local Operating Network) and Modbus RTU communication protocols, allowing seamless integration into distributed control systems and SCADA platforms. Its IP67-rated enclosure ensures protection against dust, moisture, and vibration, making it suitable for field-mounted applications. In addition to robust signal handling, the module operates reliably across a wide temperature range and is certified to CE and UL standards.

Therefore, the 9905-968 is widely used in power generation, oil & gas, water treatment, and manufacturing environments where precision, durability, and network compatibility are essential.

Technical Data

Typical Applications

• Power Generation: Acquires analog sensor data for turbine and generator control systems.

• Oil & Gas Automation: Monitors pressure and flow in pipeline and compressor stations.

• Water Treatment Plants: Interfaces with level, pH, and temperature sensors for process regulation.

• Manufacturing Systems: Supports analog monitoring in chemical, food, and material processing.

• SCADA Integration: Communicates with supervisory systems via Modbus RTU for real-time diagnostics.

For instance, in a water treatment facility, the 9905-968 can collect data from flow and pH sensors and transmit it to a central controller for automated dosing and filtration. In addition, its IP67 rating ensures reliable performance in wet and dusty environments.
